Not using the belt yet but may. Not just here everywhere on amazon.
The concept is great but the functionality is poor. It is so flimsy it falls into the cracks. It just creates a huge lump, doesn't stay put and overall just too bulky.
The band only fits horizontally across an adjustable but it does not hold the beds together. Installing requires extreme tightening of the provided strap around the two separate mattresses, greatly deforming them. It loosens almost immediately.
These bed sheet suspenders hold the oversize table covers together making the arm extensions stay in place. Bought a king adjustable bed, now need single sheets.
Upholstery nails & fixers don't always do the job completely. They do a great job, but installing them is a hassle on this bed.
They seem to be very cheaply made. They're also very tough to open, i need the leverage of a spoon to open the clips. If you open the clasp too far it pushes down on the clip so it won't go on the sheet.
