Hidreamz4 PCS Bed Sheet Fasteners, Bed Sheet Holders for Keeping Sheets On Mattress, Fits from Twin to Queen to California King

I got these after swapping a deep memory foam mattress to a smaller one. All my fitted sheets would come off and wrinkle in the night and these seemed like a cheap way of perhaps fixing this problem! It has been extremely helpful. I was concerned that the plastic bits would snap but so far they have been ok. One has started to bend but I do tend to throw myself into bed which doesn't help. My only issues with them is when i toss and turn in the night i sometimes end up with the top of the plastic which pokes into me (its a single bed up against a wall) and that can hurt at times. - This is because my mattress is not very deep (18cm!) so the plastic bits really stick up. Other than that they have been very effective!

I bought these for a super king-size devan apsolutely useless. Because there isn't a frame on the bed they just pop out from under the mattress and end up on the bed with the sheet. I did however heat them up and bend them flat so I could attach them to the side of the bed with a screw which worked brilliantly they do hold the sheet well just needed modifying for my bed type.If you have a wooden frame bed then your good to go otherwise buy the 6 point elastic braces type which I ended up getting as couldn't justify buying another 2 packs of these just to modify to have enough for such a big bed.

The seller was efficient but the item was not as expected. The base of the device is very thick and causes the edge of the mattress to raise up, not leaving a flat bed. This was for a Tempur mattress so this may not happen with a conventionally sprung mattress.

They do not stay attached very well

This product isn't suitable for a duvan, it pops out from under the mattress. If u move too much in bed then the buttons pop off too. If u get out of bed in the night be careful not to stab your leg with one, it hurts.Good points they are simple to use and IF they stayed put then they would work well.

Works quite well, not very pretty on the sight. Also, can only be placed where the slats are not, which means only on the 'long' sides but also can be used to fix mattress in place

Easy to use and keep the sheets on well, but the bit that holds the sheet can pop off quite easily when knocked

Thought would do the job........ but bent over time. Don’t know if mattress was to thick or what but just didn’t do the job for me. Sure they will work for normal size mattress x
