Wow! I can only sit in my older (yet still in really good shape) about 5 minutes before sciatica sets in. I've been battling this for the last year and a half, so I finally took the plunge and started looking for a replacement chair. I'm a sewist/crafter so this pain was keeping from doing what I love or paying the price.To my great delight, this chair has great seat bottom support and doesn't apply pressure on my hip bones which results in pressure on the nerves coming from my back. I must add that I've been through physical therapy and am still doing homework, but I was regressing every time I worked on projects.Ok, back to the chair. Easy & fast to assemble.It's made largely from plastic molds, but I'm hoping for it to last a long time as nothing seems fragile.The padded seat is covered with decent fabric that feels good. There is no padding on the armrests, but I rarely use those and they are comfortable to rest my arms on. They swing up and out of the way very nicely, too.It's easy to unlock it for rocking, but I probably won't end up using this feature and I don't like chairbacks to recline without putting up my feet.I like the 360 degree swivel and will use the heck out of this as I use a few stations to create projects.It rolls great on my faux wood ceramic tiles (even better than my old chair)!Last but not least, my main workstation is low for this 5'2" maker, and it fits with plenty of leg room under my customized table.All in all, if this chair continues to be a relief from sciatica, it's a true bargain for the cost. Hopefully it lasts a good long time. I highly recommend this as a comfortable task chair, that looks great and offers quite a few color options.
