River Stones Tactile Set brings five distinct surfaces into one collection. Each stone features a different material—cork, aluminium, foam, TPE rubber, and concrete—selected for clear contrasts in firmness, temperature, texture, and grip. This variety engages tactile receptors in feet and hands, sharpening discrimination and encouraging confident foot placement. A gentle slope increases forefoot pressure to amplify sensory feedback and support balance, alignment, and motor control. Suitable for free exploration and structured training, the set integrates naturally into play spaces, therapy rooms, and PE sessions.
