Question: How difficult is it to get it onto the mattress?
Document: The mattress protector required 2 people to put it on. It was difficult tell which was the bottom and which was the top, and ended up having to redo it. It is indeed waterproof. However, it is also very slippery. The fitted sheet has a tendency to slip off the mattress during the night. The sheet now sounds like plastic when we get in bed, or roll over.
This was a lot easier to get onto my double-mattress situation than we expected. I have a 4&#34; memory foam on top of a thick California King mattress. First we unzipped the two halves of the new pad. We rolled up the memory foam and removed it, stood the mattress on its side, and placed the bottom half of the new pad on the box springs.
When I bought a new queen bed last year, I bought this mattress protector for it. Glad I did! I got a new kitten who sleeps in bed with us and she had an "accident" last week on my side of the bed. All I had to do was blot up the mess, use an enzymatic cleaner to get the smell out of the protector, then unzip the protector and wash everything. The protector stopped any liquid from leaking onto the mattress and everything was fine.
My girlfriend and I purchased this protector for our Sleep Innovations 10" Sure Temp Memory Foam Mattress (Queen) as an extra line of defense for the brand new mattress. The product was delivered two days early, it was packaged perfectly and was very easy to get out of the box and onto the bed.It took us a few minutes to orient the protector correctly but part of this was due to the difficulty of manipulating the memory foam mattress enough to get the protector underneath it.
I really like the material its made of............it feels like part vinyl and part cloth. And the zippers made it easy to put on my mattress which would have otherwise been very difficult.
I love this mattress pad! It is the best one I have ever had! It was a little difficult to put on my bed. You really need two people for that job. With this mattress pad my fitted sheet stays on the bed better and longer. I love everything about it. I would buy it again!
Cover is plastic which makes it very hot to sleep on. You can almost immediately feel the heat radiating onto the parts of your body touching the bed, even with it covered with another cotton mattress pad. Woke up drenched in sweat the first and only night I used it. I will be purchasing a cotton cover for allergy protection even if its not waterproof.
This mattress protector is very well made and sturdy. I had a little trouble figuring out quite how to put it on when I got it, but once I got it onto the mattress, I'm very pleased with it. I've taken the top part on and off a couple of times and that was very easy to do because the top part zips off separately. Much easier to use than other ones I've had in the past, with which you had to take the entire product off.
Between drooling and a lot of sweat that my boyfriend and I expel while we sleep this certainly seems to do the trick. When I got the mattress protector in I did a simple test to see how it would fair against water. I trickled some water onto it and it slid right down the side. Water did not seep through into the material like I feared it would. 5 starsHypoallergenic: I'm the kind of person that breaks out into hives and rashes when things aren't clean.
The Malouf was bulky - difficult to put on a mattress. The size of this was also way too large for the typical mattress. Lots of extra fabric so it doesn't fit well. The zipper doesn't seem to enclose as effectively either.Yes- it does the job of protecting the mattress, but the excess makes the sheets look funny.I would recommend the AllerZip Waterproof Bedding Encasement instead (what I bought for the boxspring).
Answer: Not very difficult.  With two people you can handle it pretty well.
