I was very surprised how thick this mattress is. My comfort level is most valuable at night. The serta mattress perfect sleeper does just that. The quality of it it’s super thick. It is more on the thicker side for some preference but for my husband and me we enjoy the thicker option. When the other is sleeping and gets up you can’t even feel that the other person has gotten up, compared to other mattresses. It is a great gift for a new homeowner or even for those who just want a new bed. I would recommend to friends and people who work nights. Because this helps you get comfortable as soon as you start laying down, you find the comfort right away.
