Buy NexGen mattress cover

Yes package delivered . The mainstay NexGen waterproof mattress cover fit was really good . I slid my mattress off foundation and the mattress cover slid right on. Not noisy or that plastic sound after you put your sheet on and lay down. Buy two to cover mattress and foundation. Good purchase. Keep mattress clean and fresh .

Worth it

I was worried my 10" inch mattress would be too thick but the protector fit snug. Definitely worth it for a cheap mattress protector, although, the first two nights sleeping on it, I noticed is made me feel slightly sweaty even though I had a sheet over it. Not sure if thats just me though.

Protection for mattresses

It was a snug fit for my thick mattress but I knew that going in. My mattress needs extra deep pocket sheets too. The material is a plastic sheet with a zipper to envelope the entire mattress. There was no funny smell. I got it because I am notorious for spilling my coffee on my bed. I put it on last night and accidentally spilled my coffee on the bed:( the coffee beaded off the mattress cover and protected the mattress. Its loud when you move around in the night. I am concerned that my dogs claws will damage the plastic material. Time will tell.
