What full body restraint products does SEI MIO offer?
SEI MIO offers full body bondage equipment for use with beds, doors and different body positions. The range includes the Bed-Spreader under-mattress system, Cross the Threshold door-based bondage cross, adjustable body harnesses, positional systems and bondage tape.
What is the SEI MIO Cross the Threshold system?
Cross the Threshold is SEI MIO’s door-based bondage cross system. Its adjustable straps fit most standard doors, while the included wrist and ankle cuffs create a classic X-shaped full body position.
Does the SEI MIO Bed-Spreader fit different bed sizes?
Yes. The Bed-Spreader has adjustable straps designed for beds ranging from single to super king. It sits beneath the mattress, so you do not need bedposts or permanent attachment points.
Are SEI MIO full body restraints suitable for beginners?
Selected SEI MIO designs can be used by beginners who start gradually and follow the supplied instructions. New users can begin by securing fewer limbs before progressing to a fuller position when both partners feel comfortable.
Are cuffs included with SEI MIO full body systems?
The accessories included vary between SEI MIO products. The Bed-Spreader and Cross the Threshold include adjustable wrist and ankle cuffs, but you should check the individual product description before ordering.
How do I use SEI MIO full body restraints safely?
Agree on boundaries and a safe word or non-verbal signal before starting. Check circulation regularly, keep release points accessible and never leave a restrained partner unattended.
