Make sure there is zero plagiarism.: Cocoon Chill mattress: Two-minute reviewThe Cocoon by Sealy Chill mattress sits on the lower end of the mid-range bracket, consistently priced at $799 for a queen during regular sales with free bedding and sheets included. It graces our best mattress guide as a suitable option for hot sleepers who don’t want to spend a lot for a specialty cooling mattress, but how does it fare in other areas, like pressure relief and edge support? I slept on a twin Cocoon Chill mattress for three weeks and asked five additional participants to share their experiences, as well. With a top knit cover made from phase-change materials, I was anticipating a cooling sensation as soon as I sat on the mattress, but to my dismay it wasn’t noticeable at all. Despite this, the Cocoon Chill effectively kept me comfortable and dry during both a sudden spring heatwave and a nighttime fever. (Image credit: Future / Alison Barretta)That’s all the more significant because all-foam mattresses have a tendency to cling on to body heat – as a rule, even the best memory foam mattresses will sleep slightly warmer than anything with springs. While really hot sleepers should still consider investing in one of the best cooling mattresses, those tend to be significantly more expensive. If it’s budget-friendly cooling you’re after, the Chill really delivers. My fellow testers and I unanimously agree that the Cocoon by Sealy Chill is a firm mattress, collectively rating it an 8 out of 10 on the firmness scale. We found it most comfortable for back sleeping, as we felt well-aligned and supported in that position; it’s definitely one of the best mattresses for back pain. (As the only stomach sleeper of the bunch, I didn’t feel my hips sink, either.) The side sleepers of the group appreciated the Chill’s responsive top foam layer that gently contoured our joints; however, it’ll turn off those who like a softer, more cushioned feel.As expected, the Chill mattress does a very good job of absorbing motion, which is a plus for couples. Edge support is surprisingly robust for a foam-only bed (though as a firm mattress, I suppose it makes sense.) My biggest quibble is with the setup process, particularly all of the plastic I had to wade through after unpacking it. The Chill mattress was also quite heavy to set up solo, and there was a lingering off-gassing odor that eventually faded upon cracking a window.Head below for more details on how the Cocoon by Sealy Chill performed in key areas according to TechRadar’s mattress testing methodology – along with general considerations regarding cost and value, ease of setup, and top competitors.Swipe to scroll horizontallySectionNotesScoreComfortFirm feel, best for back sleeping, responsive feel.N/AValueLower mid-range, far cheaper than specialist cooling beds, always 35% off.4.5/5DesignSimple but effective. 10-inch tall, 3 layers of foam, phase-change cover.4/5TemperatureImpressive for the price – cooling cover works effectively.4.5/5Motion isolation Absorbs movements well, suitable for couples.4/5Edge supportEdges are plenty sturdy enough for most people and uses.4/5Customer serviceFree delivery, 100-night trial, 10-year warranty.

Better yet, we regularly see Cocoon by Sealy promo codes that knock an extra $25 off, dropping the sale price of a queen Chill mattress to $774. Since the Chill is exclusively sold at Sealy, there’s no need to browse third-party mattress sales for lower prices elsewhere.Nectar is the closest competitor when it comes to value. A queen Nectar Mattress is typically on sale for under $700 during Nectar mattress sales, with free bedding and pillows occasionally bundled in. Nectar also offers a 365-night trial and lifetime warranty, which beat Sealy’s 100-night trial and 10-year warranty. But, as our Nectar Mattress review says, it’s not a dedicated cooling model so it may sleep too warm for some. See exactly how the two compare in our Nectar vs Cocoon Chill mattress face-off.Value for money score: 4.5 our of 5Cocoon by Sealy Chill mattress review: Materials & designA 10-inch foam mattress with four layersHybrid and Extra-Chill Foam upgrades availablePhase-changing cooling cover is spot-clean onlyThe 10-inch Cocoon Chill is a 4-layer mattress with a six-inch polyfoam support base, motion-absorbing comfort foam, contouring memory foam, and a stretch-knit cover woven with Phase Change Materials (PCM) to draw away body heat. The cover is advertised as ‘cool-to-touch’ but that wasn’t my experience, as I’ll elaborate on later.(Image credit: Cocoon by Sealy)For an extra $199, you can upgrade to the Extra-Chill Foam model, which infuses phase-changing materials into the comfort foam and adds an enhanced cooling cover. Meanwhile, if you’d prefer a bouncier and slightly cooler bed, the Cocoon by Sealy Chill Hybrid mattress adds a layer of coils and starts at $739 for a twin. The cooling cover is not removable for washing, but you can spot-clean stains. That’s all the more reason to invest in one of the best mattress protectors to safeguard it from spills, bed bugs, and allergens.Cocoon Chill mattress review: Comfort & supportRated firm – 8 out of 10 on the firmness scaleMost comfortable for back sleepingNot for those who like a plusher mattressI slept on a twin Cocoon by Sealy Chill mattress for three weeks. Since comfort is subjective – and I can only speak for myself as a 5-foot-4, 145lb side/stomach sleeper – I asked five people to nap on it for at least 15 minutes, after which they’d share their impressions. My group included men and women of varying ages, builds, and sleep needs.(Image credit: Future / Alison Barretta)We found the Chill mattress slightly firmer than Sealy’s self-assessment of medium-firm, giving it a collective score of 8 out of 10 on the firmness scale. This consensus was consistent among our testers, with the lowest individual firmness rating (7.5) coming from the largest participant, a 6-foot-3, 250lb side/back sleeper.For most of our back sleepers, the Cocoon Chill provided plenty of lumbar support and even weight distribution. The side sleepers among us liked the Chill’s subtle contouring and pressure point relief along the shoulders, hips, and knees. As the occasional stomach sleeper of the group, I liked that my hips didn’t sink below the rest of my body.Petite to average-sized sleepers found the Chill mattress comfortable, despite its firmness. However, one tester (6ft, 190 lbs) felt it might not provide enough support for larger individuals, although our heaviest participant was satisfied with it. Those who prefer a softer mattress may find the Chill too firm. A heavier back sleeper in the group who’s accustomed to a soft foam mattress at home says he aggravated his lower back injury after trying the Chill mattress.(Image credit: Future / Alison Barretta)To further test the Cocoon Chill’s pressure relief, I placed a 50lb kettlebell in the center of the mattress. It compressed about 1.5 inches, then quickly snapped back into place upon removing the weight. That’s not a deep drop, but it did translate to the ideal amount of pressure relief for my fellow testers with joint and back pain.Sleepers who want to sink into their mattress should take a look at our Saatva Loom & Leaf mattress review instead – or if you’re exclusively a side sleeper, the Helix Midnight mattress is made especially for you. While the larger sleepers of the testing panel felt supported by the Chill overall, a hybrid…
