Question: Does it shift and come up from the sides?
Document: I'm in love with it. keeps me super warm at night. It does shift but not as often as you may think. I come home and cant wait to lie in my bed. makes me feel like i'm  sleeping in a hotel bed
This is a very comfortable mattress pad, no question, but we had to stop using it because none of our sheets fit it properly and would come off all the time when we were sleeping. Also, weirdly, our comforter kept sliding off of us, I think because the overfilled pad would shift toward the bottom of the bed at night, pulling everything with it. Too bad, it was very soft.
Plus I love the sides and how it fits snug on the corners and doesn't come off the corners. Michele
Padding  does not come down over the sides of my mattress as shown in the photo. The elastic stretch material does allow for a deep mattress sides cover though. The complete sides of the  mattress will be covered with room to spare.
The material the sides are made with is smooth, yet durable and stays in place fairly well, although there is some sliding around. The corners have never come undone. We purchased a set of sheet corner bungees but realized we don't really need them. The topper has washed and worn well over the last 6 months that we've had it.The Bad:The pad does move around a bit over time, causing it to hang over the edge on one side or another.
Really enjoying this product. I beats buying a new mattress! My only complaint is that it does shift a bit if your mattress is the standard (not deep) type.
Unlike most mattress pads that shift around until your bed looks like a relief mao of Colorado, this really stays put. Extremely comfortable as well.
Fits well, padding does not shift, provides some softness, and you should sleep a lot better. It did not totally cure my hard lumpy mattress problem, but only a new mattress will do that.
This mattress pad is very soft. However it does shift a little bit. I don't think I would purchase again. It is nice for the price I paid but if you have a normal size washer it doesn't fit.
This mattress pad fits well to the mattress and does not bunch or shift. We use this on a memory foam mattress. The pad keeps the mattress from being too hot and gives a soft transition from the top of the mattress. The pad was better than expected and we would buy one again.
Answer: It has deep side pockets so it does not ride up.  I have never has to adjust it once I make the bed after laundering.  We both really love it.
