These are decent sheet holders. Have a little patience with them, though. Well, lo and behold, the things actually work.

Straps are a miracle. They work great for an adjustable bed. I use these for my duvet cover for my bed.

Sturdy clasps. They hold everything in place. They are sturdy, and keep a good grasp of the fabric which makes it stay around the counters of the bed! Clips are easily attached ans locked to sheets.

Don't waste your time or money on these. What a waste. Already ordered a different kind. Yes, but still, if a product doesn't work, it's worthless.

The clips are hard to open abd close and made marks on the sheet. They are easier to attach but they didn’t really work for us. It's a pretty thin microfiber sheet from target, and the clips just don't work well with it.

For a while we used straps that crisscrossed under the mattress. No retrieving them under the mattresses. It takes a lot of time and is very difficult if you are doing it single-handedly.

They do work just haven't figured out best configuration yet.

Clip keeps sheets on the bed in spite of the determined attempts of children to squirm their sheets off. Strong and hold the fabric covers in place - no slipping or popping off.

This is poorly made junk. The clips are not strong enough for couch covers. Don't waste the effort.
