Care
Topper cover care instructions
Tip: make sure the cover is completely dry before you zip it back onto your topper.
Machine wash gently
Unzip the cover and take it off the topper. Wash it on a gentle or delicate cycle with mild detergent, following the care label.
Air dry, no high heat
Air dry the cover. Tumble drying or high heat can shrink it and change the fit.
No bleach
Skip bleach and harsh cleaners. They weaken the fibers and can change the fabric's color.
Spot-clean small spills
Dab small stains with water and mild detergent. Store a spare cover in a cool, dry place out of direct sunlight.
Mattress Topper Cover FAQS:
Will this cover fit my topper?
Yes, if your topper is 2 or 3 inches thick in a standard US size, Twin to California King. It fits Turmerry toppers and standard toppers from other brands.
Do I need a cover for my mattress topper?
You don't have to have one, but it helps. A cover keeps the topper clean, so you only wash the cover, and it makes latex easier to handle when you change sheets. It also stops a latex topper from sliding around.
Which depth should I choose, 2 inch or 3 inch?
Choose the cover that matches your topper's thickness. If the 2-inch cover is out of stock, the 3-inch cover also fits a 2-inch topper.
What is the cover made of?
GOTS certified 150 GSM organic cotton. It's soft, breathable and quiet, with no crinkling sound.
Where is the zipper?
The zipper runs along one short side and extends 6 inches down each long side, which makes it easier to slip your topper in and out. It isn't a full wrap-around zipper.
Can I machine wash the cover?
Yes. Wash it on a gentle or delicate cycle with mild detergent and follow the care label. Air dry it, because tumble drying or high heat can shrink it and change the fit. Don't use bleach.
Is the topper included?
No, the topper is sold separately. You can find our mattress toppers here.
Will you put the cover on my topper?
Yes. When you buy our latex mattress topper and this cover together, we'll install the cover for you, free.
