The mattress itself is good and easily inflates once out of the box. Delivery was fast too, but that's all the positive things I can say about the mattress. The length and width are off. I bought the king size and it's definitely not 76" x 80". I complained to Wayfair and the very nice agent was able to send me a replacement with 40% refund of my initial payment. However the length and width of the replacement weren't any different from the first, which is very disappointing. The mattress left about 5" gap between it and my King  platform bed. I had to fill the gaps with boxes and cover it up with my comforter. It's not a lasting solution but I can't afford buying another mattress right now. I should have bought it in a local store. That said, Wayfair has a very good customer service team and the resolution they offered me was fair. I have bought a number of things from them and didn't have any bad experience with those other items.
