  • LUXURIOUSLY SOFT: Its pleasingly dense, luscious fabric adds an extra layer of comfort to your latex, memory foam, or any foam;
  • FITS LIKE A GLOVE! Completely encase your bare foams and enhance your comfort layer. Unquilted, this form-fitting cover keeps you as close as possible to your memory foam or latex layers and at the same extent provides a substantial barrier to help you sleep cooler and protect your foam from many of the harmful elements like dust, sweat, and sunlight;
  • STRONG AND DURABLE, you can expect this cover to last for many years;
  • EXTREMELY BREATHABLE AND ABSORBENT for added comfort. The thick fabric offers a great layer of insulation and a cool sleeping surface in hot  temperatures;
  • FLIPPABLE, two-sided: The same 100%-certified-organic-knit cotton-fibers fabric is sewn to build the entire cover, allowing it to offer the same comfortable sleeping surface if flipped over. We do not use a cheap FR treated non-skid material for the bottom to cut costs;
  • EASY 360 DEGREE ZIPPER ACCESS. Full opening allows you to remove the top cover to access your foam layers easily or if you need to spot clean or air it out;
  • SAFE: Not treated with any harmful chemicals. Not flame retardant. Our fabric is OEKO-TEX Standard 100 certified, and 100% of its strands are GTOS-certified organic cotton;
  • NOT WASHABLE. NOT WATERPROOF-we recommend to use fitted-style waterproof protector if needed;
  • MADE IN THE USA of fine quality materials and workmanship: Our fabric is milled in the USA, and the cover is sewn locally in the USA
  • (Note: On rare occasions the fabric appearance/design may vary slightly. However, we ensure and guarantee that the rest of the specifications will be the same.)

Encase your latex or memory foam without significantly reducing and changing its softness and feel. Latex and memory foam are exceptionally smooth and luxurious, and for most of us who have experienced them, they are the ultimate comfort layers. Therefore, choosing the right material to cover them is very important as it can make or break the final comfort level for the sleeper.

Our unlined and unquilted soft and breathable knit cotton fabric mattress and topper cover (or encasement) fits like a glove and enhances the feel of any foam layers that it covers. The natural all-cotton fabric is highly absorbent and creates a luxuriously cooler sleeping surface.  To the more environmentally conscious people like us, the fabric is completely biodegradable.

Our zipper cover offers a 360-degree protection from the elements like dust, moisture, and sunlight as it effectively keeps your foam layer (or layers) together. A proper full encasement not only improves comfort for you, but it also reduces, if not eliminates, the chance of mishandling and accidentally tearing the foam layers at times that you may need to pull your mattress straight or move the mattress topper around.

Our SleepLikeABear Organic zipper covers are locally sewn in the USA using fabrics that are milled also in the USA. The fabric consists of only certified organic cotton fibers and no other fibers. Certified organic fabrics are certified to be purely natural-that means no harsh chemicals were used from the planting and harvesting and to the production of the fibers that can be milled into fabrics. Unlike many other so-called "certified organic" covers, every cotton fiber strand of our fabric is GOTS certified organic, which makes our fabric truly a 100%-certified-organic-cotton-fibers fabric.

As a vital feature, heavy-duty, rust-proof separating zippers are used and stitched with extremely durable and heat resistant Kevlar thread. The zipper is easy to zip and unzip, and is guaranteed not to easily fall apart. It completely opens on all sides so that the top panel of the mattress cover can be removed.

We have sold thousands of zipper covers over the years- our customers have experienced that our zipper covers surpass many other inexpensive advertised covers!

High Quality, High Comfort

Pairs well with soft latex without protector. 9" cover fit 10" layers (9.5" once stacked) without overly stretching or becoming taught.

Exactly As Described

I assembled a DIY mattress of four layers (three 2" latex, one 3" foam) about 9-10" tall. I chose the 9" mattress cover, and it was a tight fit. Good thing the material is stretchy! The cover firmed up my mattress a little bit, but not as much as a quilted cover would have. Overall, I'm quite pleased with the cover. It holds my layers together well, which will allow me to actually rotate my mattress. Unfortunately, since the cover is soft and stretchy, and my mattress is floppy, it's still very difficult to rotate -- but at least it's possible now! I definitely recommend this cover for squishy DIY mattresses.

Good quality cover

We bought this cover for our self-made mattress. It is of great quality. We are very satisfied with it.

Great Cover! Very Stretchy!

I got this cover for my 11" DIY mattress and it is absolutely perfect. My mattress has a pocket coil base with two latex layers, and I wanted to preserve the feel of latex as much as possible. This mattress cover absolutely does that, while at the same time reducing some of the classic latex bounciness and masking the feeling of the holes in the latex.

I do have to say the cover is very stretchy! There is no need to order up - I wish there had been an 11" size, but unfortunately I was sure the 9" would be too small so I went with the 12". When I took it out of the box and started laying it out on the mattress, I wasn't sure that I would be able to zip it up!! But, then I started zipping and ended up having a decent amount of fabric left. Honestly, I think if they had a 10" it probably could have squeezed onto the 11" mattress - if you have a shorter mattress I would recommend ordering at exactly the right size or maybe even an inch down.

Organic Cotton 360 zipper mattress cover

Love it - Exactly what I expected. I bought the organic cotton 360 zipper cover for 12" mattress knowing (ok, hoping) it would stretch perfectly to accommodate a 13.4 to 14" thickness because I wanted a snug fit for the multi layer open cell foam mattress I created. (6" foam base layer 100 ILD, 3" foam layer 70 ILD, 3" foam layer 50 ILD and 2" dunlop latex topper 44 ILD) all stacked like a deck of cards and the mattress cover works great without stressing the zipper, providing a snug fit. It was quite pricey, but very happy with my purchase. I'ts soft and comfortable, and the zipper is good quality and open/closes very smoothly.
