Before you buy the RestTwill Waterproof Mattress Protector King: quick tips
- Measure your mattress depth, including any topper, before ordering, and compare it with the 6 to 21 inch range.
- Confirm that you need King rather than California King, because the two sizes are not interchangeable.
- Follow the care steps on the listing, since high heat or bleach can damage a waterproof backing.

RestTwill Waterproof Mattress Protector King coupon & promo code FAQ
What is the RestTwill mattress protector promo code?
The deal page lists code 4NQAQD8Z for 75% off. Enter it at checkout on Amazon and look at the order summary to confirm the reduction has been applied before you place the order.
Is it noisy?
The seller says the flexible TPU backing is noiseless, so you should not hear crinkly plastic noises when you turn over. That is one of the main points on the listing.
How deep a mattress does it fit?
The listing says the wrap-around skirt fits mattresses from 6 to 21 inches deep. Measure your mattress with any topper on it before ordering to be sure it will fit.
Can I wash it?
Yes. The seller says it is machine washable and dryer friendly: wash in cold or warm water, tumble dry low, and avoid bleach and ironing so the waterproof layer lasts.
Is 4NQAQD8Z still working?
It was active when we last checked on Oct 23, 2026. Seller codes usually run 24–72 hours or until a set number of uses is gone, so apply it soon. Our team marks a code as ended as soon as members report it.
Is there a RestTwill Waterproof Mattress Protector King coupon or discount code?
Yes – 4NQAQD8Z is the current Amazon promo code (75% off). Amazon calls it a promotion code; it works the same way as a coupon or discount code at checkout.
Do I need Amazon Prime to use it?
No. Promo codes work for any Amazon account unless the promotion box on the product page says Prime-only.
Why didn't the code apply?
Usually a different size or color than the one the code covers, a one-per-account limit, or the code sold out. See all the fixes.
