The Tumbl Trak Boundex Cuddle Box turns movement into something that feels like a full-body hug. Children bounce, stretch, push, pull, and settle into its layers of responsive Lycra - each action triggering the kind of deep proprioceptive and vestibular input that helps developing nervous systems feel grounded, organised, and ready to engage. Available across Canada and the US through The Sensory Supply, this is one of the most clinically respected sensory motor tools available for early childhood, and one of the most genuinely fun.

Developed by Eileen Richter, MPH, OTR/L, FAOTA - an occupational therapist with more than 50 years of paediatric experience - the Boundex was originally created for clinical settings and is now used by families, travelling therapists, and OT clinics worldwide. Its patented design (Patent 9,314,389 B2) is the result of decades of hands-on expertise in children's hospitals, preschools, and neonatal intensive care units.

Why the Boundex Cuddle Box Works

• No rigid instructions needed - children naturally find their own way in, developing movement confidence through self-directed exploration rather than guided drills
• Supports both arousal and calming - the same Lycra layers that invite active bouncing and climbing transform into a cosy retreat for sensory regulation when a child needs to settle
• Travels wherever therapy happens - the frame breaks down in minutes with Easy Adjust D-2 Knobs and fits in the included carry bag, making it equally practical for home visits, clinic sessions, and school-based OT
• Low-barrier setup - assembles quickly without tools, so it gets used rather than sitting in a cupboard
• Safe for everyday use - foam-padded cross braces, securely fastened Lycra layers, and rubber feet keep the structure stable during active play
• Easy to maintain - all three Lycra layers are machine washable, and replacement Lycra sets are available separately when needed
• CPSIA compliant - all materials meet US consumer product safety requirements, giving purchasing teams and institutional buyers the documentation they need

Key Features of the Tumbl Trak Boundex Cuddle Box

• Sturdy Steel Frame with Foam-Padded Cross Braces - Built from heavy-duty steel with foam padding along the perimeter rails, creating a stable, impact-resistant structure that children can push and pull against with full force without the frame shifting
• Three Layers of Responsive Lycra - Multiple layers of stretchable, machine-washable Lycra are securely fastened at the corners, providing graduated resistance that responds dynamically to every push, stretch, weight shift, and resting position
• Easy Adjust D-2 Knobs - Quick-release knobs allow the frame to be fully disassembled without tools in minutes, making it practical for families and travelling therapists who need a sensory tool that moves with them
• Included Storage and Transport Bag - The set includes a dedicated carry bag sized to hold the disassembled frame, so the Boundex stores neatly in a cupboard or travels in the back of a car without additional packing
• Rubber Feet - Stabilising rubber feet prevent the frame from sliding during active use on hard floors, keeping the structure safely in place during weight-bearing, rocking, and directional movement
• CPSIA-Compliant Materials - All materials meet CPSIA (Consumer Product Safety Improvement Act) requirements, confirming they are safe for children and meeting the purchasing standards required by schools, clinics, and institutional buyers
• Designed in the USA - Developed and designed in the United States by Eileen Richter, MPH, OTR/L, FAOTA, with input from decades of paediatric clinical practice

Skills Your Child Develops with the Boundex Cuddle Box

• Proprioceptive & Vestibular System Awareness - Central to the Boundex experience, activating both sensory systems simultaneously as children move, weight-shift, and balance, helping to build the body awareness and spatial grounding that supports regulation and focus
• Fine & Gross Motor Skills - Developed through grasping, weight-bearing, pushing, pulling, and symmetrical full-body movement in every direction - top to bottom, left to right, front to back, and rotationally - building the coordinated movement patterns that underpin daily physical activity
• Respiratory & Cardiovascular System Awareness - The Boundex encourages expanded, deeper breathing as children engage their core and move actively within the Lycra layers, supporting better breath control and encouraging freer vocalisation
