My first disappointment was that the seat height is at least an inch and a half lower than described in the specs, which (due to a disability) was the reason I ordered it.  I also discovered that the hardware for one of the wings is misaligned, so it won't slide on; it's possible that I could force it, but I can see that if I did so, it would be visibly crooked (and might cause further damage to the chair, which is pretty flimsy). Planning to return this item.
