The SENcastle Family: Choosing the Right Sensory Integration Tool for Your Setting
A professional guide to understanding how SENcastle, SENcastle Access, SENcastle Light, and SENspark support therapists, educators, and the children they serve.
SENcastle products
Sensory integration is not a luxury — it is a clinical necessity for many children and adults navigating developmental disorders, motor difficulties, communication challenges, and sensory processing differences. Yet finding the right professional tool that genuinely fits your environment, your clients, and your therapeutic goals remains one of the most underaddressed challenges in assistive technology.
The SENcastle product family was born from that exact gap. Developed by Integratum / E-Glas — one of Europe's leading assistive technology innovators — each product in the lineup is designed with a clear clinical intention, grounded in real therapy settings and built around the needs of the professionals who use them daily.
"SENcastle isn't just a regular product. It's a tool that supports therapists, teachers, parents, and — most importantly — helps children overcome their challenges."
This guide walks you through the full SENcastle family: what each product does, who it's for, and how to choose the right fit — including a detailed side-by-side comparison table.
What Is Sensory Integration Therapy?
Sensory integration therapy — rooted in the foundational work of occupational therapist Dr. A. Jean Ayres — focuses on helping the nervous system process and respond to sensory input in a more organised, functional way. For children with autism spectrum disorder (ASD), ADHD, intellectual disabilities, cerebral palsy, or developmental delays, poorly integrated sensory processing can affect learning, communication, emotional regulation, and daily functioning.
Professional sensory integration tools work by providing structured, multisensory input across five key systems:
Auditory (sound and hearing)
Visual (light and colour)
Tactile (touch and texture)
Vestibular (balance and movement)
Proprioceptive (body position and pressure)
The right tool creates a safe, engaging environment where the nervous system can practice making sense of the world — reducing anxiety, supporting focus, and enabling participation.
Meet the SENcastle Product Family
The SENcastle lineup currently comprises four distinct products. Each is anchored in the same core philosophy — accessible, clinical-grade sensory stimulation — but tailored to different environments, user profiles, and therapy contexts.
SENcastle (Original) — All-in-one Compact Sensory Room
The original SENcastle is the most comprehensive sensory integration tool in the family. It functions as a complete, self-contained multisensory environment — ideal for schools, clinics, hospitals, kindergartens, and therapy associations looking to create a dedicated sensory space without committing to a purpose-built room.
At its core is a central light column with visual effects, surrounded by a tactile fabric tent with waterproof, anti-bacterial, and anti-fungal properties. It includes 42 sensory cards generating 210 distinct sensory scenes and 6 sensory cushions, offering virtually unlimited therapeutic variety.
Key features: 42 sensory cards · 210 sensory scenes · 6 sensory cushions · Central LED light column · Headphones · Adjustable sound & light · Therapy handbook · Easy 2-person assembly
SENcastle Original
SENcastle Access — Table-sized · Wheelchair accessible · AAC compatible
SENcastle Access was built around a single guiding principle: inclusivity. Designed specifically for individuals who use wheelchairs or live with CVI, it brings the full SENcastle sensory experience to users who would otherwise be excluded by traditional sensory room setups.
Crucially, it supports switch scanning and eye gaze control — making it compatible with AAC (Augmentative and Alternative Communication) systems including DialoQ Talk, Grid 3, Communicator 5, and TD Snap. This makes SENcastle Access an essential tool for working with non-speaking individuals and complex communication needs.
Key features: Wheelchair accessible design · Switch & eye gaze control · AAC system compatible (Grid 3, TD Snap, DialoQ Talk, Communicator 5) · Table-sized format · 42 sensory cards · 2 sensory cushions · CVI-friendly visual output
SENcastle Light — Compact · 5-minute setup · Sensory room add-on
SENcastle Light is the entry point of the SENcastle family — designed for settings that already have some sensory infrastructure and want to enhance it with a powerful visual and auditory element. At just 1.07 metres in height and with a setup time of under 5 minutes, it is the most portable and deployment-ready solution in the lineup.
It's particularly suited for itinerant therapists, classrooms with existing sensory equipment, or any setting where space and setup time are premium. Despite its compact form, SENcastle Light delivers the same clinical-grade LED light column with adjustable sound and light intensity as its larger counterparts.
Key features: 5-minute assembly · Height: 1.07m · 42 sensory cards · LED light column · Adjustable sound & light · Most portable option · Self-standing element
SENspark — Interactive mid-tech AAC device · Multisensory · Individual & group use
New Product Developed in Croatia in collaboration with Croatian professionals.
SENspark is the newest and most distinctly different product in the lineup — not a sensory environment, but a handheld, interactive mid-tech AAC device combining sensory stimulation with communication support. It bridges the worlds of play, communication, and learning.
Each SENspark unit can light up, vibrate, and play sound in response to touch, movement, or special RFID activity cards. Its silicone casing is ergonomically designed for children with varying motor abilities. In group settings, multiple SENspark units connect wirelessly, enabling collaborative structured activities — a unique feature not found in any other product in the family.
Key features: Records up to 60 min audio · Light + Vibration + Sound · RFID activity cards · Motion-responsive · Wireless group sync · Toy control compatible · Step-by-step sequencing · 30+ activity manual · Available in sets of 5 or 10

Who Should Choose Which Product?
While every product in the SENcastle family can serve a wide range of needs, here are the most fitting use cases to guide your decision:
SENcastle (Original) — Best for:
Schools, clinics, and therapy centres building a standalone sensory space from scratch. Best when you need maximum sensory range and immersive therapy sessions that engage all five sensory systems.
SENcastle Access — Best for:
Settings serving wheelchair users, AAC communicators, or individuals with CVI. Wherever inclusivity is the priority and traditional sensory room setups create barriers. Essential for SLPs and occupational therapists working with complex communication needs
SENcastle Light — Best for:
Itinerant therapists, classrooms with existing sensory equipment, or any environment where portability and speed of deployment are essential. Also ideal as a visual enhancement to an existing sensory room.
SENspark — Best for:
SLPs, special educators, and occupational therapists running structured individual or group sessions focused on communication, cause-and-effect learning, and sensory-motor development.
The SENcastle Approach: Therapy, Not Just Technology
What distinguishes the SENcastle family from generic sensory room equipment is the clinical intentionality built into each product. Every unit ships with a professional handbook filled with therapy ideas, session structures, and practical guidance for moderators. The team behind SENcastle — backed by E-Glas, one of Europe's leading assistive technology companies and the organiser of the ATAAC conference — offers both live and online onboarding sessions to support a strong therapeutic start.
SENspark takes this further: it was co-developed with special education teachers, occupational therapists, and speech-language pathologists, and its included manual contains over 30 structured therapeutic activities, each adaptable to individual or group settings across a wide age and ability range.
For therapists and educators, this means less time troubleshooting equipment and more time doing what matters — delivering meaningful, evidence-informed sessions that support children in reaching their potential.
