This is an excellent mattress

Ultra firm mattresses are not for everyone. You have to understand that this mattress is nothing like any of prior mattresses you have used. It will shock you the first time you lay down on it, But ! Once you use this Ultra firm mattress for a few weeks and break it in , you will no longer be able to sleep on regular mattresses like firm, medium or soft. Everyone says that their mattress is the best mattress ever but it's relative. This is an excellent mattress that has excellent support and I believe that is much healthier for your back and body

Fantastic

[This review was collected as part of a promotion.] This is my first time using the Sealy mattress and I'm super excited and impressed. The mattress is very comfortable and built with quality. The mattress is very firm and can withstand a great amount of weight to it. It does not get hot and stays cool throughout the night. It was very easy to install. Much more comfortable than other mattresses and I highly recommend it .

Omg this bed is so comfy.

[This review was collected as part of a promotion.] Oh my gosh. This bed is beyond comfortable. I have a lot of pain from playing sports and I have slept so good lately because of this bed. You can stand on it and it doesn’t sink that bad or move the other person. It is supportive in all the right places. I love this bed so much.
