Greetings on this cold cold day you see I got the house code on Today, I am going to be putting together a new office chair. My son has been trying to come into your mind wanting to spin around and always sit down when I'm trying to do some work on the computer. So now we have two office chairs. We're going to go ahead and put this together do a quick review. Thanks for watching. All right, brand rose Morris. It's an ergonomic chair. comes in at 40 pounds inside the box. One thing I think is really funny. Their slogan is long time sit no tired. It's made in China.

One of the hardest parts about quitting Anything together is unboxing it because that's going to take the most time you want to make sure that you don't damage anything was pulling it out, you want to check for damage, make sure that you have all the pieces you need before you put it together so that if it's damaged, you can easily send it back. Let's pull everything out and I'll show you what we
got. All right, we got the user manual here. Once again, long time sit, no tired. ergonomic chair. It's got the instructions here. So this is a basic chair assembly and shows you how to put it together we're going to do step by step. These are the parts that it comes with. So we got the base, we got the wheels, we got the arms, the back as well as the seat and the mechanism that makes it work. It does come with an Allen wrench, but if you do that it's going to take you twice to three times the amount of time to put it together. We use an impact and the size for the one that you're going to need is three sixteenths allen wrench.

The box itself was a little banged up.  Looks like this one came a little bit discombobulated, it also comes out with an Allen wrench, we're going to see if we can reconnect it without having to turn it back in. But basically, what you have here is a each one of these sides fits into a hole, the spring goes on this back edge here. So let's see if we can pop that together so it'll be easy install and don't get scared. If you're looking for all the bolts they are all pre installed on the base cushion. So basically you just take them out, put on the pieces where they go, put them right back in, right so we found the best way to do this is pull off the top spring. There is a nut on the back, undo the nuts so this will come off and then we can easily attach it where it goes.  

Alright, we got it back up and ready to go. Now we can go ahead and re attach it to the back
All right, ready go fully functional pressure push him into he told.  Flip it over,
stick it inside this guy here. When this extends this whole thing comes up with all right first we want to attach the main mechanism. Like I said you pull out pull out the bolts. And this is going to be the front, you're going to have your adjuster wheel towards the front. Line up your holes.
What you want to do is you want to pre thread them about three to four threads down to make sure that they're going in there straight so you don't strip them when using your impact. So we're going to install our homes now.

Once again, you want to pre thread screws a couple to make sure that you don't strip the threads. If you strip the threads, you're going to be really unhappy. We're going to do this for both going to pre threat them a couple threads to make sure that we don't struggle So now we're going to go ahead and put this on the base and then we're going to attach the headrest. All right, you see inside there, there's where we're going to attach the headrest. So we just slide the headrest in, put it where we want it
and we're going to attach this through the other side and tighten it till we like it. Last but not least, you can put on the designer music caps. So, pop it in and it's ready to go.  

All right, this is the completed project came together pretty nicely takes about five to 10 minutes to put it together takes longer to unbox it.  Alrighty, live nice and smooth. Almost makes you feel like you're a kid again. What do we think is it nice thumbs up or thumbs down. All right on the left hand side, it's got the lever. You pull it up and the back will go forward and You have the button here where you can go up or down and remember the mechanism I told you about will make it go up or make it go down by using this lever here as well.
