SertaClassic Alden 11.5" Medium Mattress - Full

Terrible mattress

I brought my mattress in February 2025. My mattress had sunken. I fall in the middle and have to sleep on the end. This is very disappointing. I assumed I purchased quality.

Big Mistake Buy

I purchased this mattress and within 2 weeks it is sagging where I lay? I know over time that will happen but not withing 2 weeks of buying it. I made a mistake with this purchase.

Good for Heavier Sleepers

Minimum motion transfer

Supportive and comfortable with it 😊

Just what I needed for a goodnight sleep.

I bought a new mattress because my old one was was 30 years old (!) and I was waking up with lower back pain. I do have a herniated disk, and I thought maybe a new mattress would help. The new mattress isn't any better in alleviating my lower back pain. I don't know whether to return it or not because I don't know whether any other mattress would be better. Otherwise, the mattress is comfortable enough, although it is 2 inches higher than my old one and makes it a little harder to get out of bed. I am 87 years old.

Well done 👏

Seems like the perfect mattress for what I needed!

Firm like its said but seems shorter and narrower

Mattress seems to be quite a bit shorter & narrower (~1") than usual for a King and I am comparing with my old Serta King size. Hopefully it will stretch out a bit after being laid flat. Btw, it is NOT a mattress in a box type.

My bed is just for me.

I purchased this Mattress because my other it wasn’t that old the other one was a pillow top and it was to hard for me to get in the bed with 2 very bad knees and it’s not too soft , it’s firm just the way I like it now I can get in and out of my bed by myself. I love it.
