Once you get the wheels on assembly is easy. You think you have them all on lift a bit to get the last one on and another falls off. My basement floor is uneven so until I firmly tapped them in one fell of. Put a board over the leg brace above the wheel and whack it with a hammer. Chair is very comfortable and easily adjustable
I bought a warranty for this chair and returned it for a full refund within two weeks. The seat was held together by staples and the seat started falling apart.
Its actually a very nice chair the mesh style makes it very soft and flexible only downside i would say is it doesnt lean back. But it spins very smoothly can be pretty high off the ground to super low to the ground perfect for what i needed. If ur lookin for a sturdy easy to put together comfortable tall/short and not super massive chair youve found the right chair here. Also very good price for what u get!
