I have really nice hardwood floors at home, so I bought Lifelong's Replacement Office Chair Wheels Rubber Chair casters to use on this chair and they fit and work perfect. I needed a tall chair that worked with my Fully Standing Desk and this chair is tall enough. It was very easy to assemble, looks sharp, and is pretty comfortable. My only two improvements would be a deeper seat because I'm 5'10, and the back support is SO BEEFY that it feels a little like I have to lean back to have my shoulders reach the back of the chair. Not sure if this will be great or not ergonomically but I didn't want to spend more than $300. I don't know what the large, center knob on the bottom of the chair does either, and it's not labeled and the instructions don't specify. I'd recommend the chair though so far!This chair is beautiful. Cannot yet speak to how well its going to hold up, but it is solid and beautiful. One thing to note - the seat is quite shallow from front to back. Unless you are very short, just your butt will be on the seat and there isn't really any support for your upper legs. I (5'5") thought my size 16 derriere might be causing me to feel I was going to slide out of it but my hubby sits in it about the same. He is 6' tall, slender, no butt. He says it's fine for sitting at the desk. We will keep it, but if I had it to do over again, that seat depth measurement would be something I would be more aware of.My first impression was whoa, this is a heavy duty chair, which... isn't a bad thing. The base is definitely not cheap plastic, it means business. It was pretty easy to assemble. Looks great and on day 2 of sitting in it, I'm v impressed. I'm of the small female variety -- 5'4" and 110. I like to sit cross legged, fold up and do weird stuff that's probably not good for my back and hips while sitting in a chair for extended periods. This chair's lumbar and neck support hits JUST right though. This may possibly be my first amazon review ever and it's all because this chair spoons me just right.The wheels roll nicely, even on carpet.I have a mild concern that the leather won't hold up long-term -- I feel like it might get loose away from the padding or that it could get stained/rub off but right now in it's fresh new-new state, it's a beaut! I'll try to remember to check back in 6 months for an update.But so far 5/5! Highly recommend.I spent a lot of time trying to find the perfect office chair for my home office. I did also buy roller blade wheels for this which makes it even more enjoyable but the support and comfort of this chair is great! It also looks beautiful and doesn’t make my office space look ugly with a big bulky chair.Where has this chair been in my life? It's been missing. That's where. I have been hunting for YEARS to find an office chair that has a back that tilts back AWAY from the seat bottom. Usually when office chairs claim that they tilt, this means the whole seat tilts back, meaning there is no movement in the individual's hinge at the hip joints. When you sit for HOURS and HOURS like I do, this is not a relief. But THIS chair back tilts back away from the seat bottom, so you actually RECLINE back. Also, the lumbar support is amazing, like super great! (Goodbye extra lumbar support pillow.) Also, the seat bottom is not too deep, meaning the backs of my knees do not rub on the seat edge. Check the measurements listed in the description because they are very helpful. My prior chair seat bottom was too deep, obviously made for someone at least 6 foot tall. I am just under 5 foot 7 inches, and this chair fits me perfectly. I can even rest my head on the headrest. It's life-changing!My only critique is that the overall height adjustment could go a little lower. I have it resting at the lowest setting and my feet do touch the ground, but sometimes I like to move my feet forward more, and the height of the chair won't really allow that. HOWEVER, I already have a footstool under my desk, so I can still move my feet forward more despite the height of this chair.The arms of the chair are lower than the usual office chair. But for me, this is great, because I type A LOT, and these chair arms stay out of my way. Then when I do want to rest my arms on them, it keeps me from shrugging my shoulders up. My lower forearms/wrists/hands touch the chair arms, not my elbows, which again is better for me, because the leather on my prior chair irritated my elbows as they rested on them.ON TOP OF ALL OF THIS, this chair is stunningly beautiful. The cream is a gorgeous, perfect cream, not yellowish and not too white, but it truly brightens up my home office which is also in my master bedroom suite. The bonded leather feels smooth and supple, and I feel like the chair looks way more expensive than it was. My husband even agrees that it looks amazing and is quite supportive. The mid-century simplistic style of the chair really pairs well with many styles. My bedroom suite is traditional/French country style, and my office furniture is more industrial/modern with wood, metal, and glass, and this chair ties in nicely with all of that.The only difficulty had during assembly was getting the rollers into the metal base. My husband had to help with this because I just couldn't get them to pop in. Other than that, the rest of the chair was very easy to assemble.The brown pseudo leather is soft and has a good feel to it. The seat cushion is firm but not uncomfortable, the back is also firm with just a little lumbar support and the angle is adjustable. I am 5'11" and have no problem with it, but I don't sit in it for more than an hour at a time in my home office. It is definitely not as supportive and comfortable as my previous executive chair. What I love about this chair is its low arm rests which allow me to sit very comfortably while using my pull out keyboard.I was looking first for comfort and for style/ beauty. This one didn’t disappoint. Assembly was easy. The only concern I had was one plastic piece on the base looks flimsy… but it’s not for function- so I’m expecting it to be ok.If comfort and this style are priority for you—- along with a good price- I recommend this chair.
