Hello, are they fitted to hold onto the mattress from underneath?

Yes. It has elastic all the way around and it fits on a thick mattress up to 11 or 12"

Yeah. They have a fitted sheet that fits underneath and a flat sheet for the top

Mmm they don't have the corner straps to hold Te mattress from underneath but inhale a queen size bed and it works just fine with the elastic

My best guess is the elastic is intended to fit under the edges of a regular king size bed, but not the European style with a pillow top (that adds from 3 to 6 inches to the depth of the mattress).

Yes, or if you strech it on the sides, it will be move towards the bottom/under the mattress. There is no way to get around that, the top part is still good though, from my experience!

Yes. They will probably make the mattress a little snug when you put it in the crib, but that is ok. We used these at every level for our mattress and currently still use them and the mattress is in the lowest position with our almost 14 month old. I love this product!

Yes! They snap on very tightly. In fact, I packed one of them way more than should be done - was overflowing from the top - and the lid snapped on so well that it even squished down all of the overflow. And then fit back under the bed. You will not be disappointed.

Yes & yes. There is an upper & a lower mattress which are linked together at a point that is set in from the outside edges, far enough in to allow you to tuck the sheets in. Pretty clever design.

Yes, there would be extra that you could tuck under the mattress. I did notice that what is under the mattress does not slip out easily, so will probably stay under there, if you tuck it under.

No. there are discs that are on the sides to keep the straps under the mattress taught. they need to hang down about 1" below the mattress.

No, but you might want to put a flat board or a flat something under you mattress

They didn't work at all for me, found them on the floor. Finally I got the mattress suspenders and they hold nicely. Hope that helps.

It has two straps and plastic pieces that wrap around to the other side of your mattress-fasten it under mattress. You can pull to adjust a secure for snug fit.

No they don't and they seem small. Its difficult to get them on our full wave mattress.

They are not attached. But the material underneath keeps them in place. Hope this helps!

Yes, they are. We have two different type hospital beds and mattresses and they fit both very well and don't "pop" off when the head or foot is raised.

Hi M. Luker, Yes the sheets absolutely do stay in place. The pad may add a little extra height to the mattress so be sure to have sheets that are capable of fitting a higher mattress. I do have one set that is not as deep, but the sheets do still stay on.

I did receive instructions with the ones I ordered. You will not see them under the mattress, however I am assume they are in a large X. They should keep your sheet in place just fine. I like them, they keep my sheet from bunching up.

Hi! These have an fitted flat. They aren't attached to the bottom sheet but are elasticized around the foot of the bed so that they stay tucked. Thanks, Jennifer

Yes! The fitted sheet may slip off if you roll around a lot because the mattress is really thick, but they do fit!
