What's Compatible?
Cocoon™ by Sealy mattresses need a solid, elevated surface to deliver comfort you can count on.
Pair your mattress with a power base for a personalized sleep experience. Plus, nearly unlimited head and foot positions to customize your relaxation routine.
Designed to remain solid and supportive, our foundations are made from high-grade wood, with a supportive structure constructed from high-gauge steel wire to give your mattress the flat, sturdy base it needs. Learn More.
Slatted foundations and platform beds can support a Cocoon™ by Sealy mattress. We require that the slats be at least 3" wide and no more than 4" apart.
Box springs are not compatible with Cocoon™ by Sealy mattresses as they need a solid base. Box springs are designed to "give" so a traditional mattress can support your weight. Learn More.
We do not suggest placing your mattress on the floor. Doing so may trap moisture underneath the mattress, damage, or invalidate your warranty.

It's like sleeping on a Hotel Bed
Jun 11, 2025
I purchased the Sealy Posturepedic Elite Hybrid High Point II Medium and I couldn't be happier. This mattress gives me that Hotel Bed feel. I loved the cooling top that this mattress comes with and, for me, it's the perfect balance between softness and support. I would recommend stopping by a store and checking out the different support levels. Also, don't skimp on sheets and pillows. I upgraded my pillows to high end down and also bought new Egyptian cotton sheets. This is the ultimate sleeping experience.
Love it!
Jun 11, 2025
I like a soft mattress but my husband likes a firm mattress. This one is the best of both worlds, somehow firm yet so comfy. My husband who has back problems and chronic all over body pain sleeps well on it. We have tried so many mattresses and this is the only one we both like. This is actually the second one like it we have bought. We had the last one for 10 years. The only problem with this mattress is that I am never comfortable on any other mattress if you can call that a problem. I can't stand to spend the night anywhere else, I just want to get back to my own bed!
Only one night on the new mattress....

What a difference!
Good Mattress So Far
Jun 9, 2025
At my age I deserve an amazing nights sleep, so I went shopping. I'm sure this mattress will be the treat I deserve. Trying the mattress out in the store is a lot softer than the one you get delivered. It's already been broken in, so giving mine time to conform to my body. In the showroom it was heaven, then the salesman pushed buttons on the adjustable frame and who knew it could get even more comfortable. So I recommend the High Point II soft Hybrid and suggest the adjustable frame to go with it. The warranties seem decent too but when they deliver it you need to take pictures of the Law tag (do not remove) before you position the bed or get the protector and sheets on. You're going to need them for registering warranty. I have only had the bed for less than a month but its worth it and so am I.
GREAT SLEEP!
Jun 7, 2025
I’ve been wanting a new mattress for a long time so I waited on a good sale and I got it!!
I downsized from KING to QUEEN and that was an adjustment! It’s been 2 weeks now and I LOVE IT!! I’m sleeping so much better!
I purchased with financing and it is worth it!
If you’re on the fence about this mattress don’t be, JUST DO IT! My first HYBRID and I LOVE IT.
I love it
