The mattress is fine! A bit on the soft side rather than firm! And the reason for a negative feedback is that this is my first time using wayfair and the first mattress came and it was the wrong size, I then had to take another day off work for the next delivery, and I'm left with a mattress I didn't want and at 4ft in width it's too big for a single bed and too small for a double?? Plus it will cost me to dispose of! Great job wayfair
