Serta 12.5" Queen Mattress, Firm.

I have the mattress for about a week, more time to tell for certain but so far so good. The mattress is firm to my liking; it supports my back way better than the medium firm mattress I used to have; for reference, I am a back sleeper. It is a hybrid mattress so there was no need to unroll, the delivery was prompt on time, and the team carried it upstairs to the bedroom, it was all good.

Mattress

States that it is medium- firm , but is more firm and no medium. Bought for guest bedroom and slept on it for 6 months while awaiting my furniture for my master bedroom in my new home. Have t0 say it really helped my back (. Permanently fractured from a fall in a barn loft). Even after receiving my master bedroom furniture with expensive mattress I still find myself taking naps on it. Great purchase for the price point!👍 PS: the bedspread %26 sheets are Mainstays and would recommend as well

This mattress is amazing. I bought when it was on sale so it is a very good deal. I got way more than I paid for. We've had it for almost 2 months, and it not showing any signs of wear. I like a firmer mattress and my husband likes a softer one. This mattress meets both of our needs.
