There is a reason ball pits are one of the most beloved pieces of sensory equipment across North America - and one of the most requested by occupational therapists. These TFH ball pool balls deliver full-body tactile and proprioceptive input in the most direct way possible: by surrounding the entire body in movement, texture, and gentle resistance.

This pack of 1,000 hollow plastic ball pool balls from TFH is the standard refill choice for sensory ball pits in homes, therapy clinics, daycares, schools, and sensory rooms. Each ball is 75mm in diameter, mixed colours, and manufactured to TFH's established quality standards for therapeutic sensory equipment.

Key Features of the TFH 1000 Ball Pool Balls

• BPA-Free Hollow Plastic Construction - Made from safe, non-toxic hollow plastic so families, educators, and clinicians can use them with complete confidence across all settings and age groups.
• 75mm Diameter - A size that balances full-body immersion with ease of grasping, tossing, and sorting - supporting both gross motor and fine motor engagement within the same activity.
• Mixed Colours - A multicolour assortment that encourages colour recognition, sorting, and visual engagement, adding a layer of cognitive and communicative play to the proprioceptive experience.
• Minimum 7 Layers Recommended - TFH recommends a minimum depth of 7 ball layers per ball pool, and this pack of 1,000 provides the depth needed for genuine full-body immersion and the deep-pressure sensation that makes ball pits therapeutically effective.
• Ball Pool Walls and Floor Sold Separately - Designed to work with TFH ball pool systems; pair with any TFH ball pool frame, inflatable pool, or soft-sided enclosure for a complete setup.
• Non-Returnable for Hygiene Reasons - As with all TFH ball pool products, this item is a final sale and not available for return. Please confirm quantity requirements before ordering.

Why Ball Pits Work - The Sensory Science

When a child or adult moves through a pool of balls, every surface of the body receives simultaneous tactile and proprioceptive input. Proprioception - the body's awareness of its own position and movement - is engaged by the gentle resistance and compression the balls provide as the body pushes through them. This kind of whole-body input has a regulating effect on the nervous system, helping individuals find calm, improve body awareness, and build sensory tolerance over time.

The colourful, lightweight nature of the balls also makes this one of the most naturally motivating sensory activities available - children reach for them, throw them, sort them by colour, and bury themselves without needing any prompting.
