Rated 5 out of 5 by from 💯 love it [This review was collected as part of a promotion.] That mattress from Serta is the best choice for someone has a backache. It’s so comfor, soft, off-gassing. I would say I like the design and recommend to everyone I know.

Rated 5 out of 5 by from So comfortable and soft! [This review was collected as part of a promotion.] Honestly this mattress is such a huge upgrade from our previous one and honestly I have been sleeping much more comfortably since we switched over. Previously we had a coil mattress with a pillow top which nice don't get me wrong but the added layer of memory foam seems to make a huge difference for me. At first my husband was unsure as he has never had a memory foam mattress before so he was worried it was going to be too firm but over time realized that the foam adapts to your form and basically "hugs" you. I definitely feel the price point on the mattress is more than fair for the quality and great sleep that come with it. I was worried as some other reviews states you can feel more movement from your partners in this kind of mattress, but I have not noticed that and honestly I actually feel like I notice less movement from my husband and I have also noticed that my husband has been snoring less from sleeping on this mattress. When we first received it I looked over the mattress and was very impressed with the stitching and the layers to the mattress and you could tell immediately that it was good quality. Another thing I really enjoy about this mattress is it seems to circulate temperature better and doesn't retain body head and make you all sweaty and uncomfortable. This is my first time having a Serta mattress and I am overall super impressed and think I am sold on them as a brand. I would definitely recommend, and also want to add that I am a person who deals with fibromyalgia as well as multiple Sclerosis so comfort is super important to me and I feel like this mattress has provided me better sleep and comfort overall. So if you are like me and you need to keep comfort in mind this is definitely a win.
