These are a life saver! First time using it. Only have to use 1to remedy the problem. The three prongs are helpful.
They are a little trickier to get on but they keep sheets in place. Are very firm, once engaged, and the installation is simple enough. They clamp very well to thin sheets and adjusts very well.
The ‘eyes’ are plastic, but they are sturdy for sheets, blankets & pleather seat covers! I have an adjustable bed so the mattress bends in the middle and raises up like hospital beds do. However, our memory foam mattress is 10”.
I would reckons these to anyone who has problems with sheets falling off their bed. I have a very thick mattress with a pillow top and 2” memory foam topper and it keeps my sheets on no problem.
Adjustable sheet straps are well worth the money and have finally solved our baggy puckering fitted sheet dilemma. I just use one strap across the width of my bed and it keeps my sheets nice and crisp.
The tension just slips looser and looser. Doesn't hold bedsheets very good.
