Better than expected
Color: Black, Size: 1 Pack
I recently bought this chair and have been thoroughly impressed with its overall performance. From the moment it arrived, the quality was clear. The construction feels sturdy, and the materials used suggest durability that inspires confidence for long-term use.
The chairs fit perfectly into my space, offering both comfort and a sleek, professional look. Their weight strikes the right balance: light enough to move easily but heavy enough to feel stable and secure. Additionally, their durability has surpassed expectations, showing no signs of wear even with regular use.
From a value perspective, these chairs are a great investment. They offer the high-end feel and reliability of more expensive options without the high price tag. Overall, I highly recommend these chairs to anyone looking for a professional, durable, and budget-friendly seating option.

Wheels role, comfortable, easy to assemble and s
Color: Black, Size: 1 Pack
This has rolling wheels and if I could put it together Anyone can. It fits me fine (250 pounds) the seat is comfortable. They gave me all of the tools (1 tool) needed. Directions were pictures and words that are large enough for me to read. I liked the lower cost and the shipping packaging was great. I’m too big to even try the recliner. I’m sure it would do it but I have had some bad experiences in the past. Don’t be fooled by reviews that state the wheels don’t move. They do. I would buy this chair again

Office Chair
Color: Grey, Size: 1
This chair is the perfect size for a small space however it was a nightmare to assemble.! The screws did not align well and some of them I couldn't tighten at all. Overall I am very pleased with the purchase it's very comfortable and sturdy for the price. I just wish the arms were a little bit higher though...

total complete junk.
Color: Black, Size: 1 Pack
STOP!!! Do NOT click on Buy. This is simply the biggest piece of **** you've ever seen. Impossible to put together because all the threaded inserts are misaligned. PLUS, it came busted. One of the arm rests was cracked all the way through. And a piss poor design, too. The back attaches to the armrests which in turn connect to the base. Without three or four people, it's simply not possible to put this worthless excuse for a chair together. And don't even THINK about using it WITH the back but WITHOUT the armrests!! Can't do it. Not possible. Terrible design. Seriously, this is right at the top of the list of useless junk I've gotten from Amazon. Not Amazon's fault exactly, they just sell the crap and at least they make it super easy to return this idiotic junk. OK, maybe it IS their fault. Shipped and sold by Amazon so there's that.... Oh, it took over a week to get here, too so there's THAT as well.
Yup, looks like a great deal at first. But....after spending half your life trying to assemble it.... Nope. Not worth one damn cent. Utter absolute junk. Last warning: DO NOT BUY THIS RUBBISH!!! Don't you do it!! Clearly I loved this purchase.
