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...
