Sei Mio Seated and Mistreated Universal Under Chair Restraint System

SEI MIO Seated and Mistreated is a universal under-chair restraint system designed to route straps under a chair to help keep a consenting partner securely seated. It’s made for bondage and roleplay where positioning matters - ideal for couples who want hands-free teasing, control, and a chair-based set-up without needing specialist furniture.

This style of restraint is popular because it uses what you already have at home. Slide the straps into place, adjust the fit, and you’ve got a stable base for playful scenes - lap teasing, oral-focused play, edging, or power-exchange moments where staying seated is part of the game.

If you’re new, it offers a clear “start point” for bondage. If you’re experienced, it’s a neat way to add structure to a scene and explore chair positions with less fuss.

How to use: Agree on boundaries and a clear stop signal before you begin. Place the system under the chair as intended, then sit your partner down. Adjust strap length slowly—secure, but never painful or numb. Check in often and keep safety shears nearby for quick release. Wipe clean after use and store dry.
