Sleep & Beyond ticks all the boxes with its full mattress encasement. This zippered beauty is genuinely waterproof and also protects your mattress from bed bugs, while being organic, non-toxic, and sustainably made and packaged. It even comes with a 10-year warranty, which is unheard of for mattress protectors!
What we like about the Sleep & Beyond Mattress Encasement
Sleep & Beyond makes its Organic Cotton Zippered Waterproof Mattress Encasement with GOTS certified organic cotton and an inner layer of TPU that is non-GMO, bio-based, and derived from corn starch. The TPU is also Oeko-Tex certified, approved by GOTS, and meets the Greenguard Gold Standard.
I especially like that the organic cotton is certified by Oregon Tilth, given the problems with reliable GOTS certification for cotton grown in India and certified by other entities.
Sleep & Beyond makes this mattress encasement to provide full 360-degree protection. The entire cover comprises TPU membrane between layers of organic cotton stretch jersey fabric. And because it has a zipper that runs the length of each side in the middle, this cover is fully reversible and super easy to get on and off.
This encasement has a clever design that makes it:
- Fully waterproof
- Great for blocking off-gassing
- Impermeable to dust mites and bed bugs
- Resistant to dander and other allergens.
The TPU has a pore size of just 3 microns, which means only water vapor gets through. The TPU is just 20 microns thick, though, so it is lightweight and not stiff or noisy.
How it performs
Unlike the PVC and vinyl waterproofing of old, this encasement is silent. No matter how much you shuffle about in bed, you won’t hear crinkling or crackling from this protector. Instead, you probably won’t even remember the protector is there… until you spill something and thank goodness that it is.
The TPU membrane is also flexible and breathable, allowing water vapor through but not liquids. That means your mattress is protected but the cover won’t make you sweaty or hot.
This encasement has a YKK zipper (made with recycled, non-toxic metal) with an organic cotton cord pull. That means it’s easy to locate and use the zipper when necessary. The invisible zipper teeth keep things smooth, though, so the encasement doesn’t affect your bedroom aesthetic.
Downsides to the Sleep & Beyond Mattress Encasement
The only mark against the Sleep & Beyond mattress encasement is that it’s only available in sizes to fit up to a 14-inch deep mattress. That means many folks won’t be able to use it, which is a real shame.
If you have a mattress that’s 14-inches deep but you also have a topper, I’d still consider purchasing this fantastic encasement to protect the mattress. That way, you can add a separate mattress topper protector or a fitted sheet-style mattress protector over the top of the whole set-up.
Sustainability at Sleep & Beyond
Sleep & Beyond goes above and beyond in its sustainability efforts. Not only does it ship this encasement in a reusable organic cotton bag without any single-use plastics, it also operates out of fully GOTS certified facilities and uses only non-toxic, organic and natural materials.
Impressively, this waterproof mattress encasement uses corn starch derived TPU, rather than synthetic materials. And the TPU is fully endorsed by GOTS, making this a GOTS organic certified mattress protector, rather than a cover where only the cotton is certified.
I love that Sleep & Beyond has a raft of social sustainability certifications too, including Fair Trade status, BSCI, and Sedex. The latter involves a comprehensive audit that encompasses:
- Labor Standards
- Health & Safety
- Environment
- Business Ethics.
Sleep & Beyond has a thorough zero-waste policy, which includes reusing fabric offcuts to test new product ideas or make accessories or packaging. It also has several GOTS factories worldwide that are vertically integrated for full control over the supply chain. Some of the factories are fully powered by solar or other renewables.
Its newest factory is in Pakistan, where it makes these mattress protectors and other products. This factory is both GOTS and Fair Trade certified.
Sizing and fit
Sleep & Beyond offers this mattress encasement in a wide range of sizes to fit mattresses from crib to Cali King. The crib size can fit up to a 6-inch deep mattress while adult sizes can fit up to a 14-inch mattress.
That said, Sleep & Beyond notes that because the fabric is a stretch jersey knit, the 10-inch option can actually fit mattresses measuring 8-12-inches deep, while the 14-inch option could stretch to accommodate mattresses 12-16-inches deep.
Care and maintenance
As with any mattress protector, spot-cleaning is best wherever minor spills occur.
The nice thing about this mattress encasement, though, is that it is machine washable, should bigger incidents happen.
As this is a full mattress encasement, it’s a bit more effort to remove than a fitted style or flat mattress protector. I like that Sleep & Beyond positions the easy access zipper at the sides, though. This makes it much easier to slip off without having to flip up the entire mattress. Just be careful to lift the mattress and ease off the cover, so it doesn’t snag on the bed frame and tear or wear.
Sleep & Beyond recommends you wash this encasement before first use, using warm water and mild detergent. Avoid chlorine bleach and tumble dry on low or line dry. Don’t iron this encasement!
Warranty and returns
Incredibly, Sleep & Beyond offers a 10-year warranty against manufacturing defects on mattress protectors and mattress encasements. It even extends this warranty to cover the surface of a new Sleep & Beyond mattress against stains should you purchase this at the same time as the protective cover (and use the protective cover properly).
Note that the company’s return policy offers a 30-day window to return your encasement for a refund, providing you haven’t opened or used the cover. If the encasement has been washed or used, Sleep & Beyond can’t resell it and won’t refund it (unless there’s a clear manufacturing defect).
Some companies, such as Avocado, offer a more generous, longer return window and refund policy. However, Sleep & Beyond’s warranty period is ten times as long as those of its competitors.
Final thoughts on the Sleep & Beyond Organic Cotton Zippered Waterproof Mattress Encasement
The Sleep & Beyond Organic Cotton Zippered Waterproof Mattress Encasement is my top choice for a full mattress encasement. This organic, natural product will safeguard your mattress against bed bugs, dust mites, allergens, spills, leaks, and stains.
The encasement is very well designed, affordable, has a long warranty, and is basically undetectable once it’s in place. That means you can rest easy, knowing your mattress is fully protected on all sides.
