Very robust fasteners and adjustable length. Keeps my sheets in place. Unfortunately one of the fasteners was detached from the elastic but easily fixed with a sewing machine.

great seller and great product

Helps to keep sheets in place, adjustable

They work as described had them in use for some time

These really could do either being longer. Very tight fit across the width of a single mattress. I didn't want them to go across the corner of a sheet as mattress fits into bed frame and that would probably make them ping off!

These do work just make sure that they have a good grip even if you have to fold over the materialto make sure the grip is secure

I've found these great for keeping the sheet in place, I also use them on the bottom corners of the quilt. Stay in place. Adjustable & good price.

8 straps supplied - sadly, one of the clips broke on first use, leaving me with 7 straps. I'm fairly adept with a pair of pliers, so I popped it all back together (there are essentially 3 parts to the lever/clip and they just snap together), but the metal is pretty thin, so once it's been bent out of line, it's never going to be the same (see photo with arrow). Shortest, unstretched length is 28cm Longest unstretched length is 54cm Instructions say not to exceed 100cm - It'll put too much pressure on the metal component, and if the clip lets go of the other side of the sheet at the wrong moment, you're going to get a high speed smack in the face from a metal clip! My eye is fine now, and the bruising has subsided. As long as you don't assume these have a similar grip to a Staffie with a stick in it's mouth, and you don't subject them to the same abuse as your brother did to your new Stretch Armstrong, you'll be fine.
