Protection Without the Crinkle.
Nylon Knit Top
A 300 GSM knit of 50% nylon and 50% polyester lies smooth over your mattress.
Quiet and Water-Resistant
The water-resistant top helps keep spills and sweat out of your mattress, with no crinkle when you move.
Deep, Secure Fit
An 18-inch skirt with a non-slip grip edge covers every FORM mattress, from 10 to 15 inches, with room to spare.
Protection That Works With Your Mattress

Protect the Comfort You Paid For
Spills, sweat and everyday oils work their way into foam over time. A washable protector keeps them on a layer you can clean. The FORM Lifetime Warranty excludes stains, so a protector is the simplest way to keep your mattress in claim-ready condition.

A Knit Surface, Not a Plastic Sheet
The FORM Mattress Protector uses a soft circular knit on top, so it stays quiet when you move and is designed to keep the feel of your GelGrid™ mattress close to how it felt out of the box.

Easy to Wash, Easy to Swap
Pull it off with your sheets, machine wash it cold on a gentle cycle, and tumble dry with no heat, because high heat can damage the water-resistant layer. No bleach. It goes back on in a minute.

Mattress Protector FAQs
It can, when the protector feels like a sealed plastic layer. The FORM Mattress Protector pairs a nylon knit top with a quiet, water-resistant surface, so it adds protection without a sticky, sealed-in feel.
Water-resistant. The top surface helps keep spills and sweat from soaking into your mattress. It isn’t a fully waterproof encasement, so blot large spills right away and wash the protector soon after.
No. The knit top stays quiet when you move, with no crinkle.
Yes. The 18-inch skirt fits every FORM mattress: FORM Core (10 inches), FORM Core Hybrid (12), FORM Prime (14) and FORM Prime X (15).
Order two Twin XL protectors, one for each mattress. Each side of a split king adjustable base can then move on its own.
Every one to two months, and right after any spill. Machine wash cold on a gentle cycle, skip bleach, and tumble dry with no heat. High heat can damage the water-resistant layer.
Only slightly. The Mattress Protector is a single knit layer designed to keep the feel of your mattress intact. You’ll notice a smooth knit surface rather than a change in support.
A protector isn’t required, but the FORM Lifetime Warranty doesn’t cover stains. A protector keeps stains off the mattress, which keeps a future warranty inspection simple.
The Mattress Protector carries a 5-year limited warranty against manufacturing defects. Normal wear, fading, pilling and shrinkage aren’t defects. The FORM Mattress Protector is final sale once delivered, like all FORM bedding. If it arrives damaged or defective, contact us and we’ll make it right under that warranty.
