Sportsheets Bed Bondage Restraint Kit

No bedposts? No problem.

This bed bondage restraint system transforms an everyday mattress into a four-point restraint setup without permanent fixtures, complicated installation or bulky equipment.

The system uses a 152 cm centre connector strap positioned beneath the mattress, with four individual 152 cm adjustable restraint straps extending towards each corner. Each strap finishes in a soft cuff, allowing wrists or ankles to be positioned separately while giving you plenty of room to customise the layout for different bed sizes, bodies and play styles.

Adjust each corner independently to create anything from a relaxed spread position to a more controlled four-point setup. Because the restraint straps are designed to sit beneath the mattress, the system can be installed without relying on bedposts or permanent mounting points.

The design is especially beginner friendly. Soft cuffs provide a gentler introduction to restraint than rigid metal cuffs, while the adjustable webbing lets you gradually fine-tune positioning instead of committing to one fixed setup.

Visually, the all-black construction keeps everything clean and understated. Black webbing, matching cuffs and low-profile hardware give the set a classic bondage aesthetic that looks purposeful without being intimidating.

Another big advantage is what happens when play is over. Simply tuck the cuffs and excess straps beneath the mattress and leave the system in place, ready for next time. It is also lightweight and compact enough to pack away for travel.

Four cuffs. Adjustable positioning. One ordinary bed transformed into a whole lot more possibility.

Why It Stands Out

This under bed restraint system gives you the versatility of a four-corner bondage setup without needing a specialist bed frame.

Each restraint strap can be adjusted independently, so positioning can be made wider, narrower, looser or more contained depending on the experience you want.

The system can also remain tucked beneath the mattress between sessions, making setup quicker when you want to use it again.

Product Care & Hygiene

Spot clean the straps and cuffs after use with a damp cloth, mild soap and warm water where required.

Pay particular attention to cuff surfaces and any areas that have been in direct contact with skin.

Do not soak unless specifically approved by the manufacturer.

Allow all straps and cuffs to air dry completely before tucking them beneath the mattress or placing them into storage.

Avoid bleach, harsh household cleaners and abrasive products, as these may weaken webbing, stitching, hook-and-loop material or plastic components.

Inspect every strap, cuff, adjustment point and stitched connection before use.

Do not use if any section becomes frayed, torn, cracked, stretched or otherwise damaged.

Store clean and completely dry away from direct sunlight, excessive heat and sharp objects.

Safety Information

Make sure the centre strap is correctly positioned beneath the mattress and check each restraint point before beginning play.

Adjust cuffs so they are secure without cutting into the skin or restricting circulation.

Regularly check restrained hands and feet for normal colour, warmth and sensation.

Loosen or remove restraints immediately if there is numbness, tingling, unusual coldness, significant colour change, swelling, pain or loss of sensation.

Avoid positioning that places excessive strain on the wrists, ankles, shoulders, hips, knees or other joints.

Never attach restraints around the neck or in any position that could interfere with breathing.

Do not use this system for suspension, lifting, body-weight support or other load-bearing activity.

Never leave a restrained person unattended.

Agree on a safeword or clear non-verbal stop signal before restraint play begins.

Keep all cuff releases accessible and make sure everyone involved understands how the restraints are released before play starts.
