awesome!!! a definite must

it fits our sons mattress perfectly. we got the twin size 6" for our 5" memory foam mattress. love the velcro patch to protect zipper and keep bugs out. love it!

Well Made Product

I am very happy with this product. It is well made and protects my mattress well. I really like the zipper tie and cover for extra protection.

Sleep Defense System Best encasement Ive found.

Bought 4 of these. The Queen size encasement to the mattress and box spring and 2 for twin size mattress. They are very soft and breathable. Very easy to clean. Strong material compared to other encasements I bought in the past that tear very easily. The zipper also had a flap and several twist ties to really secure the zipper. I think if you have bed bugs they would be hard to get out. I bought these as a preventative measure. But I'm very pleased and these are probably the best ones I've ever bought.

Very good

We just bought it. First few days of usage is good. Fits well and no awful smell.

Like it

I only gave it 4 stars cause it's new and I don't know how well it will do yet. I don't have bugs to keep out. I bought it when I purchased new mattress set & more and more you are hearing about bed bugs and anyone can get them. I liked the feel of the material and the velcro flap that covers the zipper. I do have a memory foam mattress on top of the encasement, so I really don't know how it would feel if I was sleeping on top of it.

I might rate this higher after a period of use, but that depends on how it holds up. It seems to be good quality, fits nicely and is not noisy. The price was great and shipping quick.

1. Mattress cover and box spring covers are sold separately and are different from each other. The mattress cover is waterproof, coated with polyurethane but the box spring cover is not. The pillow encasements are sold as a pair, and they're also coated.

2. No, it doesn't come with a box spring cover.
