Product Overview

Bring the relaxing vacation feel into your home thanks to this Beautyrest Hotel Diamond 4.0 hi-loft pillow-top king mattress from Simmons. Built with two layers of pocket coils, this bed supports every body part for the best sleep you could want. An ergo comfort layer features both latex and viscose to cradle you as you rest. Meanwhile, four inches of gel-infused AirCool® foam provides a relaxing space. With AirCool BeautyEdge® foam encasement surrounding the coils, feel free to stretch out every which way.

This sleep set includes one mattress and a split boxspring. Made from two smaller boxsprings, a split boxspring provides the same support as a single boxspring when used together yet is much easier to manoeuvre through tight spaces.

Comments about Beautyrest Hotel Diamond Simmons Beautyrest® Hotel Diamond 4.0 Hi-Loft Pillow-Top King Mattress Set:

We have been sleeping on this bed for almost a week, and I can say that each night my comfort level seems to increase.

After returning a super plush mattress which caused back pain, the support in this one was a welcome relief. Initially, it feels quite firm. There is not a lot of give when you lay on it. After a few days though, the pillow top foam seems to soften a little bit. We are noticing a *slight* body indentation on my husband's side (he is 190lbs, I am 105) BUT extensive googling tells us that this is quite normal in most foam mattresses; foam compresses, which is a trait that also allows it to provide comfort.

My favourite things about this mattress are the motion isolation and how cool it stays during the night. With 2 adults and a dog sharing the bed, little to no movement is felt when someone is moving around or getting up, and the consistent temperature is sooo lovely. Both of these features definitely contribute to a more restful sleep.
