The essentials
Loving Joy Under the Mattress: what you need to know before you buy
Is it for you?
Who the Loving Joy Under the Mattress is for, and who it isn't
It suits you if…
- You want to try tying your partner to the bed without ropes or knots.
- You want to restrain wrists and ankles at the same time with a single system.
- You prefer a fastening that releases quickly if someone wants to stop.
- You're new to bondage and want something easy to set up.
Better look elsewhere if…
- You prefer a buckle or lock fastening. These cuffs fasten with Velcro.
- You want to tie someone up somewhere other than the bed. This system goes under the mattress.
- Your bed isn't a double. The only size listed is for a 185 × 155 cm bed.
Step by step
How to use the Loving Joy Under the Mattress
- Agree a safeword or signal first to stop, and a non-verbal signal in case someone can't speak.
- Place the system under the mattress so the cuffs sit at wrist and ankle height.
- Adjust each cuff so it holds without being tight. You should be able to fit one finger between the cuff and the skin.
- Check in often on how the other person is feeling, and check their hands and feet.
- To release, open the Velcro on each cuff.
Cleaning
Wipe with a damp cloth and a little mild soap, then let it air dry completely. Store it with the Velcro fastened so it doesn't catch on other things.
Our advice
- Never leave the tied-up person alone, not even for a moment.
- If they feel tingling, numbness or cold, or their skin changes colour, release that cuff straight away.
- Don't put anything around the neck.
- Change position every so often so you don't strain the shoulders or hips.
- If the cuffs irritate the skin, stop using them.
What the science says
What the science says about talking about consent as a couple
The studies we cite did not test this restraint system. What they looked at is how couples communicate consent, which matters a lot when someone is tied up.
Across three studies, the first with 392 adults, feeling a high level of internal consent and using explicit verbal cues was associated with greater sexual and relationship satisfaction. Bondage specifically was not studied.
