CalExotics Boundless is an under bed restraint system that turns almost any bed into a space for consensual bondage. Four adjustable cuffs attach to strong tethers that slide beneath the mattress, so there is nothing to fix to the frame. It suits couples trying full-body restraint for the first time and those who want a comfortable, secure setup. Soft plush linings and vegan leather exteriors keep wrists and ankles comfortable.

Why Choose the CalExotics Boundless?
Many beds do not have posts or rails to tie to. An under-mattress system solves that problem and can be set up in minutes, then tucked away when not in use.
Velcro-style closures also make the cuffs quick to release, which is an important safety point. Combined with the swivel clasps, the Boundless offers a good balance of security, comfort and quick release.

How to Use and Care
Lay the tethers across the bed and slide them under the mattress so a cuff point reaches each corner. Adjust the tether length, then clip on the cuffs and fasten them around wrists or ankles, leaving room for one finger underneath. Agree a safe word before play, check circulation often and never leave a restrained person alone.
Spot-clean the cuffs with a damp cloth and mild soap, then let them air-dry. Store the system dry and folded.
