Bedside kits, kits that go under the bed and can be left there, bedding kits of all sizes, 4-piece strap kits, 6-piece strap kits, kits for bed bases. Add kinky to your sex life with easy-to-use strapping kits. The kits usually come as H-shaped straps that go under the mattress, with a handcuff attached at each end of the straps. Because they are under the mattress you can sleep and change bedding as usual, but be aware, not all strapping kits are designed under the mattress. Some come in the form of loops that wrap around the mattress and are therefore less comfortable to sleep and change bedding when they are on the bed. The kits do come with handcuffs on your hands and feet, but if you want you can detach them and only handcuff your hands or your feet.
