Comfortable!

This mattress is very comfortable. We have a different Serta (Lambdon) in our room that is still comfortable after 9 years. This blue lagoon is in our guest room so it should last a very long time.

Serta so good

Literally got this mattress because the one I had was out of stock and thank goodness!! So nice and soft and firm at the same time first time my bed hasn't hurt since replacing it with the old mattress

Super comfy mattress

My niece & her husband had one in their spare room and we liked it so much we bought one for our room. We simply couldn't be happier with the mattress. Mind you we've only had it for a month total. Soft, but not squishy if that makes sense…as it's still very supportive.

Blue Lagoon- nights

So far so good. Comfortable, yet supportive. I like that it has motion deterrent. I've always gone with Serta mattresses, quality for a great price.

Too firm

Most expensive mattress we've bought I did tons of research before buying and this one had great reviews. Tried it for several mos and can't get used to it. Just bought a different one we like much better so put this one in our spare bedroom

Looked comfy

When i tried it at store it felt good!! Now I'm feeling dips in the mattress and just bought it around 12/03/2025! So only 5 months old and that's not good
