Product was visibly misaligned. The base where the backrest was fit onto was not of uniform height causing the backrest to stick out at different heights on either side. I have requested a return. Will update the review based on how that goes.
Update 1: Wayfair refused a return and refund. They instead ordered a replacement for the problematic part.
Update 2: The part Wayfair sent was incorrect. I reached out again, and now they are resending the correct part.
Update 3: After more than a week of waiting, the 2nd replacement has not yer arrived. The first incorrect replacement is uselessly sitting in my home; I have to find a way to trash it, as it is too large to go into regular trash.
