High quality Protector !!

CustomerFebruary 23, 2026✓ Verified purchase

This is a very nice mattress protector. It is soft and there is no "plastic" noise. Quality material. It fits perfectly on our deep mattress that also has a pillow top so it's extra thick. A cut on my arm from a rose bush put a drop of blood on the protector, so I sprayed it with cleaner a few times and scrubbed it and voila' it disappeared. This is not one of the cheapo protectors. I prefer quality, and this protector delivers ! Read more

Perfect mattress cover

TobygardenerOctober 20, 2025✓ Verified purchase

Gives extra softness and comfort to sleep on. Easy to put on mattress and fits perfectly. Much better than my previous mattress cover. Read more

Great as a topper but not waterproof

phoenix_dreamsMarch 4, 2026✓ Verified purchase

I keep a plastic mattress cover on my child’s mattress all the time and this mattress protector is great over it. It isn’t water proof by any means like the plastic but it does create enough of a barrier to keep the plastic from making him sweat all night. It’s just thick enough without being really heavy. I will say that the material does start to wear oddly over time. It pills up and pulling the pills off causes some strands to come with it. Still I would recommend as a topper to a plastic cover. If you need something truly waterproof this isn’t it. Read more

Great product for the price.

CustomerFebruary 14, 2026✓ Verified purchase

Soft, and fits well. Also doesn’t trap heat. Has a nice lofty feel to sleep on. Just a week in but so far so good! Read more

★★★★★

great product!

murphys lawOctober 20, 2025✓ Verified purchase

This has been one of the best mattress protectors I have ever used. Very low noise. Fully waterproof. I like that it is slightly thicker, very durable, and i know my mattress is protected from everything Read more

Very nice mattress protector

Lisa D. SteegeSeptember 26, 2025✓ Verified purchase

I was looking for a better mattress protector for my foam mattress, and I found this one to be very soft, with just enough cushion to feel luxurious. Fits over mattress easily and stays put. Read more

It doesn’t change the feel of your mattress

Evanice CibJanuary 20, 2026✓ Verified purchase

The mattress protector is very soft, I didn’t know what Tercel was until I got this… kind of Jersey type of fabric over a super thin tiny foan. It does not change the feel of your mattress softness or hardness. Stay cool while sleeping on it - the old cover I had was kind of down comforter type and heated up the bed - I live in Florida ! I gave only 3 starts because I had to sew in the four corners a 2 inches wide elastic band strap as well as an elastic band strap across the sides in order to keep the cover in place. The skirt is so flimpsy and elastic band is way weak just add useless fabric under the sheets. Maybe if my mattress was taller (it is 11.5 tempurpedic) it would fit better. For the price, it should have elastic straps on the corners. Read more
