We liked the mattress protector overall. I ordered them two one for my master queen bed and the other for my guest room bed. Overall the protector is really good and looks the same as it was shown in the image page. I tried pouring water and it got removed off easily without getting absorbed down the layer, which is what we would want for a waterproof for any accidental leakage!! We are using it now for since a week and were hoping we should have bought them earlier. It’s good in texture and I layer them with my fitted sheet and extra sheet on top of it!!

Give your mattress an added layer of protection with our MatresSkin mattress encasement. Designed to keep your mattress at its peak performance, our moisture wicking MatresSkin wraps tightly and securely around your mattress to extend its life.

This encasement just glided down the length of my 18" Serta high top mattress like a super soft silk slip, so that was my first happy moment. I've slept on the encasement for about one week now, and I'm very pleased as it is indeed a)noiseless b) moisture wicking. It feels very well, with a bit of leeway around the mattress, but not so much that it slides around. Best of all, I'm truly enjoying the sensation of a deep restful sleep, and actually feeling the full comfort of my mattress through the softness of the encasement material. Bedgear's packaging of this product seems environmentally friendly as well: a simple, reusable zip case and a branded shipping box. Pricewise, I'm happy with the cost of this product and consider it a very good value. I highly recommend this product!. Ann Marie. North York, ON. Mon Apr 06 2026
