I purchased this a few months ago but find it a bit too soft for my needs. Throughout its use, it was in the protective cover and sat under my mattress protector. I live in a pet-free non-smoking household. This mattress topper retails for $359 on the Tempur-pedic website and on Amazon. here is the description provided:
3" MEMORY FOAM MATRESS TOPPER: Instantly improves the comfort of any mattress, evenly absorbing the force of your body and its pressure points to reduce tossing and turning so you can wake up feeling refreshed.
PRESSURE-RELIEVING MEMORY FOAM: Signature TEMPUR material adapts to your unique shape, weight, and temperature to offer the same pressure-relieving comfort and support found in our tempur-pedic mattresses.
REDUCED MOTION TRANSFER: Designed to reduce motion transfer so you can rest undisturbed even when you're sleeping beside your partner, kids, or pets, helping everyone get a blissful night of sleep.
MACHINE-WASHABLE COVER: Protected by an ultra-soft, hypoallergenic cover featuring Safe-Guard Technology, and the cover can be removed and machine washed as needed for easy cleaning.
QUEEN SIZE TOPPER: Fits neatly over queen size beds, and the Staytight corner straps keep your topper securely in place by creating a nonslip connection to your mattress.
