The chair was used for about 2 weeks and the arm rest bent with little to no pressure.  The part of the chair that raises it and lowers it with the lever stopped working today as well.  My son is 160lbs and now it just drops into a lowered position when sitting.  Sad about this as it was a Christmas gift and it was a main gift  as well.  That said Wayfair was excellent with the refund process a full refund and no return we just have to donate or dispose of the product.  That alone will keep me returning to wayfair for household items
