Description
No frame. No furniture. No modification required. The Under-Bed Restraint System fits beneath the mattress and stays completely out of sight until you need it — a cross-shaped strap system with four fully adjustable attachment points, designed to work with any standard bed.
Built from 100% polyester webbing with elastic connecting straps and zinc alloy hardware, the system sits flat under the mattress and adapts to a thickness of 1.2–2 cm. When in use, hand and foot straps adjust from 14 to 30 cm. When not in use, it disappears completely. No visible traces. No dedicated storage needed.
“Always ready. Always hidden. No installation required.”
