WEBVTT 00:00:00.000 --> 00:00:04.080 Across the years of me unboxing chairs, folks in the comments have said that 00:00:04.080 --> 00:00:08.280 my sitting posture is not so good. So today, we're gonna be bringing in a doctor 00:00:08.280 --> 00:00:12.480 to tell me how good my sitting posture really is. And the chair that we're gonna be doing that with 00:00:12.480 --> 00:00:16.160 is the Razer Isker V2, which I have here. 00:00:16.160 --> 00:00:19.780 We unboxed the first one on this channel a couple years ago, enjoyed it, let's take a look. 00:00:19.780 --> 00:00:24.360 I'm actually daily driving a Razer chair right now, the Fujin Pro that we unboxed the last video 00:00:24.360 --> 00:00:29.520 on this channel. But what's really cool about the Isker, and something I haven't really seen since I did that video, 00:00:29.520 --> 00:00:33.880 is their Lumbar Sport System, which they've improved for this model. So I'm really excited to see what they've got. 00:00:33.880 --> 00:00:39.920 Maybe I'll have to switch my chair out again, I don't know, we'll see. This is pretty standard compared to the Fujin Pro 00:00:39.920 --> 00:00:43.880 and the other Razer chairs that we've unboxed. What I enjoy is that they have the gauntlets. 00:00:43.880 --> 00:00:49.620 Don't shoot from your chair, no rockets. Don't surf it, don't sit on somebody sitting on the chair. 00:00:49.620 --> 00:00:53.680 It is time to take your throne. Put the sheet to see the assembly guide, 00:00:53.680 --> 00:00:58.840 or check out the video. Got what's inside, assembly looks good, looks clear. 00:00:58.840 --> 00:01:02.240 Let's see if I can do it, all right. Everybody's gotta stay organized. 00:01:02.240 --> 00:01:06.200 We got our instructions there. We're gonna part our pieces in nice little order. 00:01:06.200 --> 00:01:10.800 So we'll get confused and then build this thing. Backrest, head pillow. 00:01:10.800 --> 00:01:14.680 Hey, these are flat, that's different. I don't believe this was flat before on the old model. 00:01:14.680 --> 00:01:17.160 Accessories, oh my God, that's heavy. 00:01:18.120 --> 00:01:21.600 The instructions want you to play co-op, but I'm more of a single player gamer myself, 00:01:21.600 --> 00:01:28.620 so we're building this thing solo. Accessories, open here, there we go. 00:01:28.620 --> 00:01:33.500 One of the things that I've liked about building razor chairs recently is that some of the screws that you need are pre-installed, 00:01:33.500 --> 00:01:37.740 so there's just less that you have to deal with. Okay, instructions. 00:01:37.740 --> 00:01:42.380 Number one, put the casters on the base. 00:01:42.380 --> 00:01:46.860 Put this part, goes in there, okay. Number two, this, like this. 00:01:48.100 --> 00:01:52.740 Number three, this is what I mean about the screws being pre-installed, which is great. 00:01:52.740 --> 00:01:56.860 They're already right here for you, waiting. We need to loosen them. 00:01:56.860 --> 00:02:00.180 These gloves look cool, and I feel protected, but I don't have a lot of grip, 00:02:00.180 --> 00:02:03.180 so it's a little bit harder to unscrew these screws. 00:02:03.180 --> 00:02:08.460 So we're facing that way. Goes like this, screw everything back in. 00:02:08.460 --> 00:02:11.980 Step three, I loosen. Step four, I tighten. This is on. 00:02:11.980 --> 00:02:16.420 Step five is now to attach this to this. 00:02:16.420 --> 00:02:18.620 I don't play co-op. Ah! 00:02:20.180 --> 00:02:22.580 Woo! Is that actually on there? 00:02:25.140 --> 00:02:28.300 It's sturdy. And we loosen these. 00:02:28.300 --> 00:02:31.780 Same thing on the other side. Next step is putting the backrest 00:02:31.780 --> 00:02:34.980 onto the base of the chair. Let's do it. 00:02:36.100 --> 00:02:40.420 Line these guys up. Something that's kind of neat is they've actually got a guide on the one side. 00:02:40.420 --> 00:02:44.900 So not all chairs have this. Sometimes I struggle actually lining them up, but it just slots in on the other side, 00:02:44.900 --> 00:02:50.540 which lines up this side, makes it really easy to install. It's great that Razer includes a screwdriver, 00:02:50.540 --> 00:02:55.220 but I'm gonna use the lttstore.com screwdriver. Last thing we wanna do is just put on these covers 00:02:55.260 --> 00:02:59.620 to where we were just screwing in everything. They were basically done. 00:02:59.620 --> 00:03:03.180 Beautiful, nice and clean. So clean! And we're done. 00:03:03.180 --> 00:03:06.740 And I'm ready to talk to the doc right after I tell you about today's sponsor. 00:03:06.740 --> 00:03:10.980 Doctor, welcome. Thanks for having me. I'm Doctor Matthew Hu. 00:03:10.980 --> 00:03:14.700 I'm a physical therapist and I've also been in gaming for the past eight years. 00:03:14.700 --> 00:03:17.780 So part of what we do is make sure that the players 00:03:17.780 --> 00:03:22.740 and pros that we work with stay healthy and be at their best and looking at your posture 00:03:22.740 --> 00:03:26.220 and your ergonomics is a part of that. People in our comments say that my posture 00:03:26.220 --> 00:03:30.860 is not very good sometimes. So I really need your help. First, do you have any aches and pains? 00:03:30.860 --> 00:03:34.980 I do not have any aches and pains. So to the best of abilities set up 00:03:34.980 --> 00:03:38.900 at whichever posture you want me to assess, whether it be gaming or work. 00:03:38.900 --> 00:03:43.380 Let's start with controllers. I've got a controller in hand right now. Yeah, just assume that natural position. 00:03:43.380 --> 00:03:47.820 And what I like to look at to start is actually starting from the very bottom 00:03:47.820 --> 00:03:51.380 and are your feet supported? Boom, yes they are, very nice. 00:03:51.380 --> 00:03:56.180 And I wanna be able to determine the chair height. If I were there, I would actually kind of like look 00:03:56.180 --> 00:03:59.220 at your leg length because that can tell us 00:03:59.220 --> 00:04:03.340 sort of agnostic of whatever chair we're using, what the chair height should be at 00:04:03.340 --> 00:04:07.900 to make sure that our thighs are parallel with the ground. 00:04:07.900 --> 00:04:11.740 And so yours actually seems a bit higher. So lower it a little bit so that your thighs 00:04:11.740 --> 00:04:15.620 become parallel with the ground. And that's just to avoid too much pressure here 00:04:15.620 --> 00:04:20.060 at the end of your thigh, distal thigh, and then or too much pressure here at your butt, right? 00:04:20.060 --> 00:04:25.700 Like if it's too high, you'll put too much pressure there, which can limit blood going back up to your heart 00:04:25.700 --> 00:04:30.340 or to your brain or everywhere else. And that can make you tired. 00:04:30.340 --> 00:04:35.740 So good, so that looks good and you lean back. So this is definitely good to know. 00:04:35.740 --> 00:04:39.540 That's the next part I look at, which is the backrest and lumbar support. 00:04:39.540 --> 00:04:43.140 With you there, I see you're obviously a little bit rounded. 00:04:43.140 --> 00:04:48.820 A little bit rounded. A little bit rounded. And that's actually okay, right? 00:04:48.820 --> 00:04:52.700 It's okay for us to sometimes be in these postures. 00:04:52.700 --> 00:04:55.820 But if I wanted to really be nitpicky and say, 00:04:55.820 --> 00:04:59.300 hey, let's do optimal, let's get optimal biomechanics. 00:04:59.300 --> 00:05:04.340 In ideal world, you'd be sitting upright. So start by sitting as upright as possible. 00:05:04.340 --> 00:05:07.540 And then, let's say you weren't doing this console. 00:05:07.540 --> 00:05:12.020 Where would you set this lumbar support? What high would you set it at? 00:05:12.020 --> 00:05:16.980 It's a great question. I have to think about that. I think a lot of people are lost when they're like, 00:05:16.980 --> 00:05:20.220 oh, where should I even put it? Probably the most common is like, 00:05:20.420 --> 00:05:24.020 let me just kind of put it where the arch of my back is. 00:05:24.020 --> 00:05:28.180 That's not a bad start, but there's actually a place where you can put it 00:05:28.180 --> 00:05:35.340 that makes it feel easier to sit upright. Right below my lower, like the small of my back, 00:05:35.340 --> 00:05:38.580 think about like at the top of my pelvis. 00:05:38.580 --> 00:05:41.700 You want the lumbar support to be there 00:05:41.700 --> 00:05:45.060 because it's essentially keeping you upright 00:05:45.060 --> 00:05:49.260 by maintaining that pressure there. So because you actually like leaning back, 00:05:49.300 --> 00:05:55.060 what I like to do is make sure that the lumbar support is set inward, 00:05:55.060 --> 00:05:59.540 so that it doesn't put too much pressure on your lower back. Can you see how far it's coming out right now? 00:05:59.540 --> 00:06:02.900 I don't know if you can capture that, Andy, but it's out there. 00:06:02.900 --> 00:06:06.060 Yeah, and so what's cool about having that ability 00:06:06.060 --> 00:06:11.780 to protrude out is if you lean back into it, it's gonna feel a little bit uncomfortable over time, 00:06:11.780 --> 00:06:15.180 but it actually can serve as a reminder 00:06:15.180 --> 00:06:18.580 for you to move more. And they've actually shown in research 00:06:18.580 --> 00:06:22.740 that the people, maybe there's people in your office that kind of fidget a lot and move, 00:06:22.740 --> 00:06:27.980 those people tend to have lower risk of developing lower back issues 00:06:27.980 --> 00:06:31.340 because they're moving more. They have more frequent postural shifts. 00:06:31.340 --> 00:06:38.420 So you can actually use it as a tool to say, wow, I know I'm gonna game for the next two and a half hours. 00:06:38.420 --> 00:06:42.660 Let me set it out a bit more so that I can just move more, remind myself to move more. 00:06:42.660 --> 00:06:46.380 Interesting, so you're saying, even if I'm not gonna get out of my chair and move, 00:06:46.380 --> 00:06:49.660 moving within the chair in different postures is actually good for you? 00:06:49.660 --> 00:06:52.980 Yes, exactly. Now let's look at the ARM rest, right? 00:06:52.980 --> 00:06:56.620 And so this one, a lot of people always get really confused 00:06:56.620 --> 00:07:00.020 on where they should actually set it up. You actually have a pretty decent setup right now. 00:07:00.020 --> 00:07:03.380 So what I like to do is help you understand 00:07:03.380 --> 00:07:07.540 where your shoulders naturally rest. So sit all the way up like this, 00:07:07.540 --> 00:07:11.980 then you shrug your shoulders all the way up and then just let it naturally fall. 00:07:13.460 --> 00:07:16.940 And that's actually the resting position of where your shoulders are gonna be. 00:07:16.940 --> 00:07:20.420 However, because you lean back slightly, that also changes, right? 00:07:20.420 --> 00:07:23.780 So then you can kind of fall into that natural position 00:07:23.780 --> 00:07:28.740 where you kind of roll back and same thing, shrug and then let it fall. 00:07:28.740 --> 00:07:32.340 And if it's coming into contact a bit sooner, just lower it a little bit 00:07:32.340 --> 00:07:35.940 because you don't want your shoulders slightly elevated. Yeah, that makes sense. 00:07:35.940 --> 00:07:39.020 I'm kind of a gremlin gamer. I think I usually have my shoulders up. 00:07:39.020 --> 00:07:43.100 I'm like... It can lead to problems, but you don't even have pain, right? 00:07:43.100 --> 00:07:46.940 It doesn't mean that it's going to lead to a problem for everyone. 00:07:46.940 --> 00:07:50.340 If you want to use the next cervical support, you can, 00:07:50.340 --> 00:07:55.060 but it's not really that necessary for most, right? If you lean back like you do, 00:07:55.060 --> 00:07:58.700 it can be helpful for you because it's gonna naturally fill up that space 00:07:58.700 --> 00:08:03.700 that will be there. So that's gonna be a nice addition for most people that like leaning back. 00:08:03.700 --> 00:08:07.860 But hey, when you're at work, you're probably not even using it. You're probably like this, right? 00:08:07.860 --> 00:08:11.140 Do you want to check out your PC setup real quick? 00:08:11.140 --> 00:08:13.700 Do it real quick. All right. 00:08:15.100 --> 00:08:19.580 Does this desk adjust? Yeah, hold on. I'm a short boy. I got to lower the desk. 00:08:19.580 --> 00:08:23.620 I mean, it only goes up. I'm too short for this desk. Are you serious? 00:08:23.620 --> 00:08:27.300 Bro. This is actually a really super good example, right? 00:08:27.300 --> 00:08:31.820 Bring it up so the armrests are level, level with the desk. 00:08:31.820 --> 00:08:34.940 But then my feet aren't gonna touch the ground. Exactly, exactly. 00:08:34.940 --> 00:08:39.540 Dude, I'm short too. I have a footrest. The main and big picture thing here is 00:08:39.540 --> 00:08:43.540 if you're moving a lot and you're getting up and taking breaks every hour, 00:08:43.540 --> 00:08:46.820 you don't have to change postures and positions. 00:08:46.820 --> 00:08:52.820 I guess if there's one thing to remember, we always just say your best posture is your next posture. 00:08:52.820 --> 00:08:56.020 So just keep moving. Well, thank you very much for your time, doctor. 00:08:56.020 --> 00:09:00.740 We'll chat soon. Before we bring a few more people on, let's just talk about some of the adjustability features 00:09:00.740 --> 00:09:04.820 that this chair has before we get to that. The first thing would be the 4D adjustable armrests. 00:09:04.820 --> 00:09:10.980 We go up and down. We go forward, backward. We can swivel and we can go side to side 00:09:10.980 --> 00:09:16.140 for four dimensions. We've got 152 degrees of, whoa, leaning back. 00:09:16.140 --> 00:09:21.060 And we've got a memory foam pillow, which I don't mind. 00:09:21.060 --> 00:09:24.580 It's fine. I'm not a big head pillow guy. Chair's rated for up to 300 pounds 00:09:24.580 --> 00:09:27.860 and up to 200 centimeters tall, which I am not. 00:09:27.860 --> 00:09:31.700 I am short. They have a leather and a fabric variant of the chair. We're sitting in the leather chair, 00:09:31.700 --> 00:09:36.820 which has a different type of leather on this one compared to the V1 and it's rated to be softer. 00:09:36.820 --> 00:09:40.140 And then the last and most important thing of this chair and the thing that I like the most 00:09:40.140 --> 00:09:44.100 about the Isker V1 that has been approved is the lumbar support system. 00:09:44.100 --> 00:09:47.340 So both of these knobs will control the support system. 00:09:47.340 --> 00:09:52.460 And what's really cool is it goes in and out. It goes up and down and it goes side to side, 00:09:52.460 --> 00:09:57.540 which is really cool. So like as I'm moving, it is still against my back 00:09:57.540 --> 00:10:02.740 and it feels firm and it feels good. So if I'm sitting across leg, I'm leaning like this. 00:10:02.740 --> 00:10:07.420 I've got back support. If I'm going like this and I'm talking to the couch, 00:10:07.420 --> 00:10:11.460 which I like to talk to couches, I guess. I don't know, still supported. 00:10:11.460 --> 00:10:16.180 This chair, whether you get the synthetic leather variant or you get the fabric variant, $649. 00:10:16.180 --> 00:10:19.460 And it comes with a three year warranty or a five year warranty if you sign on 00:10:19.460 --> 00:10:22.820 for their extended warranty program. Now that I'm the doctor, 00:10:22.820 --> 00:10:27.820 we're going to bring a few people on. I'm going to roast their postures. Most doctors have four to eight years of training. 00:10:27.820 --> 00:10:33.020 I've had about four to eight minutes. So this is ought to be good. Sven is our first victim or patient. 00:10:33.020 --> 00:10:36.980 I mean, I heard that you were chosen because you have the worst posture and Belle told you to come down here. 00:10:36.980 --> 00:10:40.380 Yeah, it's exactly true. Why? Why? Why do you have bad posture? What's wrong? 00:10:40.380 --> 00:10:44.180 I don't know. It's probably hunched over like this is how I usually sit. 00:10:44.180 --> 00:10:47.420 Neck far forward, you know. Just show me how you play Counter Strike. 00:10:47.420 --> 00:10:51.340 How do you sit when you play Counter Strike? You're tall. You probably don't need the Apple box, right? 00:10:51.340 --> 00:10:55.100 No. All right. All right, let's take this Apple box out of here. 00:10:55.100 --> 00:10:58.220 This is for short people like me. 00:10:58.220 --> 00:11:02.420 All right. How are we sitting here? You need some, you typically sit back. 00:11:02.420 --> 00:11:06.900 Do you sit in the chair when you game? I try more to, but as soon as I start gaming, 00:11:06.980 --> 00:11:11.700 I start slowly leaning forward. Slowly leaning forward. So I've been told that you don't, you don't need this. 00:11:11.700 --> 00:11:16.660 You don't, you don't need this pillow. It's gone. Well, then you don't have to sit like that. 00:11:16.660 --> 00:11:20.380 You don't have to sit like that. That feels terrible. I mean, basically, if you're sitting forward, 00:11:20.380 --> 00:11:24.900 you don't need the neck pillow. That makes complete sense. So, okay, we start with the feet. 00:11:24.900 --> 00:11:30.820 Feet around the ground. He's tall. He's, his legs are pretty close to perpendicular. 00:11:30.820 --> 00:11:34.540 I mean, should we, should we lower that chair a little bit? 00:11:34.540 --> 00:11:37.540 I don't know. Probably, we could probably lower the chair a little bit. 00:11:37.540 --> 00:11:42.180 Let's lower this a little bit. Oh my God. Next up is the lumbar support system. 00:11:42.180 --> 00:11:45.620 So right now, how does it feel on your back? Feels very nice. 00:11:45.620 --> 00:11:49.140 Very supportive. Very supportive. Is this better or worse? Terrible. 00:11:50.500 --> 00:11:55.340 I like a lot of lumbar support. Okay. So basically, if you're leaning forward a lot, 00:11:55.340 --> 00:11:58.820 you should have it further out so that it kind of corrects your back posture 00:11:58.820 --> 00:12:02.940 as you're leaning forward. It makes it harder for you to sit terribly. 00:12:02.940 --> 00:12:06.900 Okay. The other thing I got told, and actually before I tell you, 00:12:06.900 --> 00:12:10.100 I need to ask you, how much do you move in the chair when you're sitting in a game? 00:12:10.100 --> 00:12:15.340 Are you pretty, do you just lock and load and just go or are you like different postures? 00:12:15.340 --> 00:12:21.100 I'd say I move around. I really like the one foot over or I'll do the cross legged to, 00:12:21.100 --> 00:12:24.380 you know? I got told that moving's good. Really? 00:12:24.380 --> 00:12:28.340 I know, I'm surprised. Moving's healthy. Really? Cause when I sit like this for a prolonged period of time, 00:12:28.340 --> 00:12:31.460 it hurts. Wait, hold on. 00:12:31.460 --> 00:12:34.620 You're sitting like that for how long? Two, three hours. 00:12:34.620 --> 00:12:37.700 Oh, that's bad. No, you're supposed to move like every hour. That's better than do that. 00:12:37.700 --> 00:12:42.660 Okay, well, you'll be okay. You're young. Do you have any back problems? 00:12:42.660 --> 00:12:45.600 Slightly. Oh, we didn't cover that in training. 00:12:47.100 --> 00:12:50.180 Last thing, Sven, is raise your shoulders up, 00:12:50.180 --> 00:12:55.020 drop your shoulders and where your elbows land is where your ARM rest should be. 00:12:55.020 --> 00:13:00.140 Oh. Right? So your ARM rest should be higher. So like, does that feel good or bad? 00:13:00.140 --> 00:13:03.820 I don't like ARM rest. Well, at the chair I have at my house, 00:13:03.820 --> 00:13:06.980 it took the ARM rest off. We didn't cover that in training. 00:13:06.980 --> 00:13:11.180 Anyways, do you like the chair? It's better than most gaming chairs I've sat in, like, 00:13:11.180 --> 00:13:14.780 yeah, it's okay. Next, our next victim. 00:13:14.780 --> 00:13:18.700 I mean, patient is Hoffman. Hoffman, take a seat, dude. 00:13:18.700 --> 00:13:22.580 Take a seat. How's your posture? Amazing. Do you have any back pain? 00:13:22.580 --> 00:13:25.940 Sometimes, yeah. Okay, okay. We'll try to fix that. 00:13:25.940 --> 00:13:29.460 Oh, does it cure my back pain? The chair? Yeah. 00:13:29.460 --> 00:13:33.340 It could if you sit right. I said how you would when you're editing. 00:13:35.740 --> 00:13:39.420 Stop. I think Belle found me like this. Stop. Is that how you... 00:13:39.420 --> 00:13:42.820 Ha ha ha. Wow. This is, I don't know a lot, 00:13:42.820 --> 00:13:46.140 but I don't know if this is great. Okay. Wow. 00:13:46.140 --> 00:13:49.660 Okay, first off. Yeah. Your feet and your legs. 00:13:50.980 --> 00:13:54.260 I mean, maybe that's fine. It's almost perpendicular. It is fine. 00:13:54.260 --> 00:13:58.060 Like, look, my hand is straight. It is fine. He's telling me how to do my job. All right, that's fine. 00:13:58.060 --> 00:14:02.220 Okay. Lumbar. Lumbar. So you're leaning back. 00:14:02.220 --> 00:14:05.300 So it should be in a little bit more. Does that feel good or bad? 00:14:05.300 --> 00:14:09.020 Worse. Worse? The other way, I had more support, I think. 00:14:09.020 --> 00:14:13.380 More support? Okay. You like that? Does it go all the way up? Bro, I don't even know what to do. 00:14:13.380 --> 00:14:17.180 You're so sludge, bro. I don't even know. I don't even know. 00:14:19.180 --> 00:14:22.520 So my... Oh, you need a head pillow. Hold on. It can cure my posture. 00:14:22.520 --> 00:14:25.880 Hold on. All right. How's that feel? How's the head pillow? 00:14:25.880 --> 00:14:29.240 It's all right. It's not bad. Okay. Next thing, if that's how you sit. 00:14:29.240 --> 00:14:33.000 It's kind of a sleep on it. Your shoulders. 00:14:33.000 --> 00:14:36.720 Okay, hop in. Can you raise your shoulders up like this 00:14:36.720 --> 00:14:40.480 and then drop them? And then where do your elbows hit? That's where your ARM rest should be. 00:14:40.480 --> 00:14:44.320 Oh, wow. You're like a magician. It's got to be lower. 00:14:44.320 --> 00:14:47.920 Okay, well, let's lower them, dude. A little bit higher. 00:14:47.920 --> 00:14:51.720 Do you use the ARM rest? Can you adjust it? I can adjust it for you if you want, but... 00:14:55.160 --> 00:14:58.440 It's not bad. I don't even know what to do. Do you like the chair? 00:14:58.440 --> 00:15:01.520 Oh, gaining chairs are kind of the same. That's fine. That's okay. 00:15:01.520 --> 00:15:04.840 That's okay. The hump feels very strong. Likes the hump. 00:15:04.840 --> 00:15:08.000 Okay? Yeah, yeah, yeah. So the technical chair. 00:15:08.000 --> 00:15:13.440 You know, I kind of need a new chair. It's actually not bad. It's strong. It's like pushing me, but it's cushioned. 00:15:13.440 --> 00:15:19.040 So that's it for me, posture potter. I like the chair. The lumbar support system is honestly my favorite 00:15:19.040 --> 00:15:22.360 out of any chair I've sat on. Even a lot of the Ergo chairs I've sat on. 00:15:22.360 --> 00:15:26.720 This is more supportive, but chairs are subjective. So I hope you learned a thing or two 00:15:26.720 --> 00:15:29.720 and make sure to like the video if you liked it. Check out some of our other videos 00:15:29.720 --> 00:15:33.360 and we'll see you on the next one. Bye.
