Attmu Sheet Straps Bed Sheet Holder Straps Fitted Sheet Clips Adjustable Elastic Suspenders Bedding Accessories Bed Sheet Fasteners for Corners, Fit Round and Square Mattresses (3 Way White)

I have a king size smart bed that is adjustable. Whenever we would sit up the sheets would come off the side, and then when we layed it back down they would come off the top corners. I wish I had a before picture to show how bad it was. Now everything stays down when we sit up, and when we lay it back down the bottom sheet and mattress protector get pulled back into place perfectly. It was quite hard to put on by myself as it has to go under the mattress, but now that its on I just unclip the sheet and leave them on the mattress cover while I change the sheet.

Great concept. But impossible to put on without the help of another person. You have to take the mattress off. I have quick zip sheets so once I got this device in to my zipper base it works awesome. But if I had plain old fitted sheets I would never use it.

does not fit twin bed well

May 2022: Reading reviews - good and bad - I understood, that I might get a working item or not. So, hoping for the best, I ordered from this seller, because of the design and the price. With no standards for sheet sizes I think this strap is a good buy. Finally I have sheets staying on the mattress without wrinkles and folds. That means more comfortable sleep. Of course to unmake or make the bed is a huge job now, especially with king size mattress. But I have no choice. One strap is sewn with clamps looking at the mattress, which is a mistake obviously, but everything works so far. September 2022: bought again for air mattress, as no sheets were staying on it. Now my unexpected guests can enjoy their sleep without fighting the wrinkled sheets. Will but again for all my other beds and for my kids and family.

they definitely work! My boyfriend somehow rips the sheets off the bed every night. And every day we had to remake the bed, no matter how much i would tuck the sheets they were always coming off in the morning. The sheet-holders definitely work! The sheets do not come off anymore! its been several weeks and the sheets wont come off unless i take them off to wash. The only problem is, it is a two person job to get the sheets back on the bed with the sheet holders. Me and my boyfriend STRUGGLED to get them on the bed the first time, now we kind of got the hang of it but its definitely not a single person job.
