4Sleep manufactures its mattresses with the environment in mind, taking care to use only renewable materials and water-based adhesives. The mattress’ components are CertiPUR-US certified, so you can be sure that you won’t be sleeping in a bed of heavy metals, formaldehyde, PBDE flame retardants or ozone depleters. As for fabrics, all 4Sleep mattresses are naturally hypoallergenic and resistant to dust mites, mold, and even clinging odors. In short, this is one of the safest and most environmentally friendly mattresses you could possibly sleep on.
4Sleep resembles a lot of the start-up mattress companies taking over the Internet these days, but its unique mattress construction sets this company apart. Coming in at 11 inches thick, the 4Sleep mattress comprises four layers of high-quality memory foam.
For starters, you’ll get a top layer that uses memory foam infused with cutting-edge Thermaphase responsive gel. This means you’ll get a responsive foam layer that adapts to the shape and weight of your body, allowing for better pressure dispersion. The gel, meanwhile, detects temperatures across the mattress’ surface and redistributes warmth to keep you within the ideal sleeping temperature range.
Underneath this layer, you’ll get an inch-thick absorbent foam layer that can dissipate motion, letting you sleep undisturbed. This layer comes with quite a bit of bounce, so you know you’ll have no problems with mobility despite the hug of the mattress’ memory foam top.
The third layer, meanwhile, bolsters the mattress’ overall integrity and provides additional support for your spine and general body alignment. Thanks to this supportive layer, you can say goodbye to the cratering that you often see from other memory foam mattresses.
Finally, a 7-inch base layer provides a sturdy foundation for your mattress — and, by extension, for your body. This durable base imbues the 4Sleep mattress with a firmness that helps with weight distribution and assists your body in staying comfortably aligned.
4Sleep also works in some resilient edge supports that will keep your mattress from sagging. Since these help maintain the integrity of your mattress’ shape, you’ll also be safe from sliding or rolling off the bed in case you’re a restless sleeper.
What’s more, your mattress comes bundled in a thermoregulating cover. Built from polyester, viscose, and Lycra, this cover is luxuriously soft even while competing with most performance sportswear in the moisture-wicking and heat-regulating department. In addition to its efficient temperature regulation, this cover is easily removable, so you can keep your mattress clean without much hassle.
Since our initial review, 4Sleep has added mattress sizes, bringing its selection up to the standard six choices. The company still only sells one type of mattress, but at least you’ll have the full range of sizes to choose from. Here are their corresponding prices:
While the prices aren’t dirt cheap, 4Sleep still comes out as much more affordable compared to mattresses of comparable quality found in most retail showrooms. After all, why spend at least $2,000-$3,000 when you can get a 4Sleep premium mattress for under $1,000?
All purchases also come with a 100-night home trial that gives you enough time to decide whether you want to keep or return your mattress. If you decide to return it within the trial period, the company will gladly refund all of your money, no questions asked. Additionally, every mattress comes with a lengthy 10-year warranty. Shipping, meanwhile, is free to anywhere in the continental U.S. and Canada. Residents of the latter, however, will need to pay a $75 handling fee to account for customs duties, as well as a $200 fee with any product returns.
If you have any concerns or questions regarding 4Sleep’s services or product, you can reach their customer support via phone or direct email. 4Sleep also has a very informative FAQ section that serves as a good first stop for any issues.
