As mentioned earlier, the Cocoon by Sealy range of cooling mattresses (opens in new tab) is attracting plenty of awards, including praise for how well it supports back and side sleepers needing extra firmness. The Chill beds have over 7,500 user reviews (opens in new tab) on the Cocoon site alone, averaging 4.7 out of 5 stars rating between them.  So why do people love these mattresses so much? Cooler sleep is undoubtedly a big draw, but here you also get the weightless feeling that comes from high quality memory foam mattresses. The Chill Hybrid is the more luxurious of the too, offering enhanced back and neck support, plus reduced motion transfer. The latter is important if you share your bed with a wriggler, as reduced motion transfer means you shouldn’t feel them moving around so much. Active Support Technology aims to support your body in a variety of sleep positions.  The Cocoon by Sealy Chill Memory Foam is the cheaper of the two. It also packs in plenty of comforting and supportive foam, and is swaddled in a soft-touch stretch knit cover designed to be breathable and cool to the touch. This could be a game-changer in summer. Both Chill models are available in sizes Twin through to Cal King, and are available on a 100-night trial, with free shipping in the States.  As for those free gifts, when you buy either Chill mattress as part of the Cocoon by Sealy Presidents’ day sale, you’ll get free DreamFit Pillows (worth up to $80) and DreamFit sheets (worth up to $119) to dress your new bed with. And if you aren’t happy with your new mattress, Cocoon has a well-defined returns, refunds and exchanges policy (opens in new tab), with most refunds processed within two business days.  Unsure whether the Sealy by Cocoon Chill range is right for you?
