Fantastic Chair for the Price - Could charge double what they do.
Color: Black
Size: 17''D
This chair is amazing for the price. We looked at dozens of chairs and finally settled on this one. Packed professionally easy to put together includes tool and extra bolts. This is an impressive engineered design that seems very high quality ESPECIALLY for the price. The only criticism there might be is the the seta a tad frim, but after a few days of use, my wife says it's very satisfactory. Can't say enough good things about it, Sturdy, but not real heavy, and perfect for home or office.

Perfect Chair.
Color: Black
Size: 17''D
This Chair is exactly what I was looking for. Rocking motion, adjustable for height length, arms that move upward or downward, nice cushion seat, and fits neatly under my small desk. I'm so happy with this purchase.

Easy to assemble, very adjustable, sturdy, well-crafted
Easy to assemble, with nicely appointed, well-crafted pieces. Solid and seemingly durable. The chair has a profoundly adjustable height—it’s a draft chair—and has a nicely stretched mesh back that provides some decent support. The frame where the arms attach to the seat is placed far enough back to not cage the thighs, and the arms are unobtrusive in either the folded or descended position. Overall, this is a very nice chair, well-made and easy to assemble at a good price for the quality and I highly recommend it.

LOVE THIS CHAIR!!!
Color: Grey
Size: 17''D
This chair checked all of the boxes for me. It’s very comfortable, easy to put together and the price was amazing compared to many that I looked at. The light gray compliments everything in my office and the raised arms allow the chair to go under my desk for more room to walk around. I have watched TV on my computer because it’s that comfy. Definitely check this office chair out.
