I gave the seat 4 stars because it came very quickly but realized something was wrong upon installing. One side would not tighten no matter what I did. I called CS while sitting on my bathroom floor and was told that they would ship me out the replacement piece that I thought I needed. Well, after going to local store and replacing it myself that same day I figured out that it was actually the toilet seat quick release tab that was the problem and not the nut. I called CS again to inform them of my findings and was informed that the original CSR already sent me a whole new seat after my first call. Even after my issue with having to change back my old seat while waiting for replacement I’m still giving 5 stars for the excellent customer service that I received. In today’s world, customer service like this is hard to come by. I’ll definitely be looking to purchase more from Wayfair again and again and again!
