A quiet corner is one of the most versatile pieces of sensory equipment any classroom, therapy room, or family playspace can have. The HABA Pro Grow.upp Platform with Lid is the foundation of a sensory bath corner that children across North America return to again and again - whether they want to sink into a tactile experience, settle in for calm sit-and-play, or retreat entirely into their own cosy space.

This platform offers three distinct configurations, all from one piece of furniture.

Remove both sections of the two-piece lid and fill the open base with balls, beans, lentils, cherry stones, or any other sensory material of your choice to create a full sensory bath. Children can explore different textures, temperatures, and weights at their own pace, building tactile awareness and body awareness through unstructured, joyful play. The filler is not included, which means you can adapt the experience seasonally or to individual needs.

Keep one section of the lid on and the platform becomes a sit-and-play area with a defined open side, giving children a stable and comforting perch while still maintaining access to the tactile fill below. This half-and-half configuration is particularly useful in settings where you want a transition space between active sensory seeking and calmer sitting.

Combine the platform with the HABA Pro Grow.upp Cover for Sensory Box Corner Cave (sold separately) to transform it into a quiet corner cave - a fully enclosed, low-stimulation retreat that fits neatly into room corners and provides the kind of safe, contained space that is genuinely restful. The corner cave frame bolts directly onto the platform for a secure, stable installation.

Key Features of the HABA Pro Grow.upp Sensory Bath Platform

• Three-in-One Configuration - Functions as an open sensory bath, a sit-and-play platform, or the base of a full corner cave so that a single piece of equipment adapts to a wide range of sensory needs and environments without additional purchases.
• Birch Wood Construction by HABA Pro - Built from real birch wood to HABA Pro's rigorous quality standards, giving the platform the durability needed for high-use commercial environments including classrooms, therapy centres, and early learning spaces.
• Safety-Designed Two-Piece Lid - The removable lid is specifically designed for adult operation only, so supervisors maintain control over when the sensory bath is accessible and children are protected when the space is not in active use.
• Corner-Fit Geometry - The 35-1/2" x 35-1/2" square footprint is designed to sit flush into room corners, making it an efficient use of space in smaller classrooms, therapy rooms, or calm corners at home.
• Compatible with Full Grow.upp System - Pairs directly with the HABA Pro Daybed Mattress (sold separately) for additional comfort, and with the Corner Cave Cover (sold separately) for a complete enclosed retreat configuration.
• 10-Year Manufacturer Warranty - HABA Pro backs all wooden products with a 10-year warranty against manufacturer defects in materials and workmanship for the original purchaser.
• Made in Germany - Crafted to DIN EN ISO 9001 standards - the international quality certification standard for consistency in materials and manufacturing processes.

Supporting Sensory Regulation, Proprioception and Vestibular Input

Sensory baths offer children rich proprioceptive input - the deep body awareness that comes from pressing hands and feet into textured fill materials, feeling resistance from beans or balls, and registering weight and pressure. This kind of tactile and proprioceptive engagement supports self-regulation and helps children move from a dysregulated state toward calm, focused readiness.

For children who benefit from predictable, low-stimulation environments, the corner configuration of this platform creates a natural boundary that reduces the amount of visual and auditory input reaching them from the rest of the room. Occupational therapists often refer to this kind of contained, structured space as a key element of a sensory diet - a curated set of sensory experiences designed to help individuals maintain optimal arousal levels throughout the day.

Ideal for children and adults across a wide range of sensory needs, including those who are sensory-seeking and those who benefit from calming input. The three-in-one design means the same piece of furniture can support different children differently on the same day.

Who Uses the HABA Pro Sensory Bath Platform

• Special education classrooms building a designated calm corner or sensory station
• Occupational therapy clinics outfitting a tactile exploration area
• Daycares and early learning centres creating nature-inspired, developmental play environments
• Families building a sensory corner at home for neurodiverse and neurotypical children alike
