I cannot fault this mattress. It is so comfortable and I'm glad I bought it even without trying it out first. However the service from wayfair was apaulling so I would never buy from them again. There is very poor/no communications between customer and delivery company. Wayfair don't seem to have a clue what's going on either. When the mattress did arrive (I was never contacted with a time as stated) the packaging was filthy, the delivery men were filthy. I was left with black marks up my walls and mud on my carpet which I've had to clean a d repaint. My wall paper was also ripped! I emailed photos to wayfair but got no response. As I said great mattress but get it from a more caring, organised company.
