  • Good Quality
Size: Twin Style: 9-12" Deep
Waterproof, fully encased, zippered mattress cover. Received it, washed it in cold water, dried on low, put it on a twin bed and it’s a perfect fit. No crackle sound, terry top. This is a cover. You may want a pad as well.

  • Sureguard mattress cover
Size: Queen Style: 17-20" Deep
We purchased a new mattress the Dream Cloud Premier Rest 16" Queen Mattress - Luxury Hybrid Memory Foam. I placed the mattress cover on by myself around April 19, 2024. I did make sure not to pull to hard and went from side to side to work it down slow to make sure I did not rip it. I’m not sure about it being waterproof as I have not spilled anything on it. I can see it being good for bed bugs as the mattress is completely covered. It felt easy to zip it up, and tuck into the Velcro to cover the zipper. There is no padding in the top cover. Our mattress is already 16in deep didn’t need anymore padding just needed a mattress protection cover and I like how it was easy to put on felt like it has extra room but not baggy and completely covers the mattress. Had to purchase new sheets and they fit perfectly over the 16in mattress and mattress cover, no problem. Only have had it on one night so we will see how it works out. It’s starting off great! ... show more

Strong, sturdy, fit perfectly, zipper worked smoothly, velcro sealed felt tight and complete. The mattress is protected.

  • Soft top, no crinkle, and accurate sizing!
Size: Queen Style: 9-12" Deep
I love these mattress encasements. They are MUCH better than the typical plasticy ones. These have a terrycloth top side that does not crinkle or feel like plastic at all. They are very quiet. I would compare these to Saferest (the benchmark, in my opinion), but feel slightly thinner. These come in more size options than Saferest, which I needed due to having a thinner mattress. These are available in multiple depths, so it's much easier to get an accurate fitting cover. The also fit true to size. My queen mattress, combined with a 3" memory foam topper, measured at 11.5 inches thick. The 9-12 inch encasement fit PERFECTLY! ... show more

  • Literally was stolen off the line...
Size: Full Style: 13-16" Deep
I'm giving this cover 5⭐️⭐️⭐️⭐️⭐️ even though I didn't get to use it. I ALWAYS prewash new bedding (Saw a documentary on bedding manufacturing...whoa). Everything about it felt quality. The Terry/nylon top "would" have been perfect for hot summer sleeping & the 360⁰ fit "would: have kept it in place. I'm a restless sleeper & hate when the corners pop off. After washing I had it on the line to air dry. It was so brilliantly white that it attracted a passerby who just couldn't resist. Hope they had a full size mattress. I'll get another next month. This time I'll have the dog in the yard... just 4 fun...lol I still recommend getting it. ... show more
