Question: Does this mattress have straps to keep it tucked in or how do you keep it tucked in??
Document: The foam mattress I'd bought was too firm for my liking, so decided to try this topper. Glad I did. It has elastic straps attached to its two corners so that it won't ride around the mattress it's covering, and these work very well. It's very cozy and fluffy, yet it still allows my foam mattress to do its thing - conform to my body. It washes (and dries) really well; the independent pockets keep the filling scattered throughout the topper when it comes out of the dryer.
This is so soft; I love it. It has straps on the bottom, so that you can secure it to the mattress. I think I will buy another one for my queen size bed!
I bought this for a second bed and it's pretty good but I use the Wamsutta Cool and Fresh Fiberbed topper (got it at Bed Bath and Beyond---not sure where else it's sold) and it's much more comfortable. The Pinzon one is certainly much cheaper though and stays on the bed easier since it wraps around the whole mattress whereas the Wamsutta has 4 straps (one for each corner). I wouldn't purchase this again but it is fairly comfortable.
I really like the soft feel of the microplush. I don't like the fact that it pulls on one side and you have to keep adjusting the pad over the mattress.
I like this very well. I do have one issue, trying to keep it tight on the mattress. Otherwise I think it is very good quality for the price.
Purchased this to keep cooler at night and it seems to work fine. Nice and plush and doesn't seem to slip or move around on the mattress. I would recommend to others
I tumbled it on low with a few dryer sheets for a bit and it went away easy peasy. I religiously keep it covered with a mattress protector so I haven't had to wash it yet.
At first I thought this overfilled mattress pad was too soft, but after I slept on it I changed my mind. This Pad is a dream! I can't keep my kids off my bed!
My biggest complaint is that the mattress pad does not stay put - even with the elastic, it rides up to the top of the bed. Between the pad itself and the elastic that holds it under the mattress is flimsy material that does nothing to keep it in place.
Good product at a good price!Bought to cover a memory foam mattress to keep the foam from getting warm - especially in the summer.This works great and does not bunch under high pressure points.
Answer: it is a mattress pad with fitted sides that have elastic. just like any other mattress pad, or just like a fitted bottom sheet.
