Oprah has had both the Cocoon brand by Sealy as well as the Hypnos mattress. And get this: Hypnos is allegedly the same mattress that the Queen of England has. In her nearly 70 years of matriarchy, one can only imagine how many mattresses she has had over the decades. God save the Queen!

The CoCoon Foundation is your entrepreneurship and innovation education platform to discover and practice entrepreneurship as a lifeskill.

The Cocoon is an all-foam mattress, built with a memory foam comfort layer, followed by a high density base layer of poly foam. The Sealy Cocoon comes in three models, but today we're testing the 10-inch Classic option.

It can take up to 48 hours to fully expand, but you are welcome to sleep on your new Cocoon immediately!

Sealy® is ranked America's #1 Mattress Brand.* Even after 140 years, we still check our work – testing above and beyond industry standards to give you the quality you need for the sleep you deserve.

Its vegan option, which replaces wool with cotton, is PETA-approved. Gwyneth Paltrow partnered with Avocado on the Goop x Avocado mattress - no, let's call it a sleep system - which starts at $24,000 and is available on demand. I chose my model during a visit to Avocado's Experience Center, at 135 Fifth Avenue.

A cocoon is a covering or case made by some animals to protect themselves or their young as they develop into adults. Moths, some butterflies, earthworms, and leeches make cocoons. (Most butterflies form a chrysalis, not a cocoon.) Moth and butterfly cocoons are made by young called larvae, or caterpillars.

Cocoon is defined as the protective covering that is made from silky threads that cover the larvae of moths and other insects such as butterflies.

Because of its medium firm feel, the Cocoon Chill may be best suited for side sleepers who weigh over 130 pounds. Side sleepers who weigh under 130 pounds may notice more pressure accumulation around their hips and shoulders since they won't sink in as deeply.

No, you cannot flip a Cocoon Chill Hybrid mattress. Doing so would result in sleeping on the firmer support layer of coils instead of the softer comfort layers on top.

With a highly adaptive comfort scale rating of 5, top-of-the-line comfort materials, and a responsive coil support system, the Sealy Posturepedic Santa Paula Medium Pillow Top is one of the best Sealy mattresses available today. Pressure relief, support, cooling, durability, this mattress has it all.

The Chill Hybrid should be pretty comfortable for most side sleepers. After the initial firm feel, the memory foam should allow them to sink into the mattress for moderate pressure relief at the shoulders and hips.
