4-Way Wrist and Ankle Restraint
The core configuration provides four restraint points around the mattress, allowing both wrists and ankles to be secured for controlled full-body positioning.
Fits Single to Super King Beds
Adjustable straps are designed to accommodate Single, Double, King and Super King mattresses, making the system more adaptable than fixed-size bed restraints.
Padded Adjustable Cuffs for Comfort
The included cuffs are padded to cushion contact around the wrists or ankles while still allowing secure restraint when appropriately adjusted.
Quick-Release Velcro Fastening
Velcro closures make the cuffs straightforward to fit and provide a fast release method when play needs to stop or the position needs to change.
Removable Cuffs and Central Carabiner
The cuffs can be detached from the main system, while the central carabiner and removable straps create additional configuration possibilities beyond conventional four-corner restraint.
Easy to Fit and Discreet to Store
The entire system fits beneath the mattress during use and can be removed and stored away when not needed, avoiding permanent fixtures in the bedroom.

If you want a dedicated bed-bondage setup, compare under-mattress systems with doorway and furniture restraints to see how each anchor method changes body position and accessibility. Bed restraints are particularly useful when comfort, horizontal positioning and flexible cuff placement are priorities.
Pairs Well With
The four-point bed setup leaves many sensory options available once positioning is established. A blindfold can heighten anticipation, while a feather, paddle, crop or flogger can introduce touch and impact contrast within agreed boundaries.
