The serta perfect sleeper nurture mattress is very comfortable. I really like it A lot. It is not too hard or too soft. It has some bounce to it. I like the comfort of the cushion and it is nice being a side sleeper and even for back sleepers. I don't have to struggle to get comfortable.  The queen mattress is true to size and is well made. It should last for years. Sheets fit it perfectly.  This is a quality mattress that I am able to get plenty of rest on.
