Back Saver

I own an Essentials Spring Euro Top 12 Medium. My model wasn't listed. I love this bed. It is not made for the adjustable bed frame. For some reason the mattresses for those frames kill my back. I had to really hunt to find this mattress. I wasn't sure if it would work to relieve my back pain. But it took two days, and the pain was gone. The bed is soft enough to be comfortable but not so soft that you can't climb out of it.

Perfect for day beds

[This review was collected as part of a promotion.] We put or Sealy Essentials Spring Tight Top Firm mattress in our daughters new room. It fit perfectly on her day bed and she loves it. I really like the way this mattress feels. It is the perfect amount of firmness and comfort.

Super Comfy!

[This review was collected as part of a promotion.] My wife and I both disagree on the firmness of a mattress. She likes to cook herself in a super soft, sinking mattress. I can't handle it. I need super firm so I don't sweat all night. This mattress is firm enough for me and soft enough for her at the same time. Not going to lie, but I still sigh in comfortable relief every night I lay down. That is until my kids kick me to the couch.

Perfect for my back

I have had this mattress for two and a half years and it is still like new. The firmness has not let up and it is perfect for my back.
