The Whitney Brothers Whitney Plus Porthole Play House Cube is the premium play house cube from Whitney Brothers' Whitney Plus Collection - a $3,002 CAD investment in a genuinely distinctive, personality-filled piece of children's classroom furniture that satisfies every state and provincial requirement for a dedicated quiet space in Early Learning environments, available across North America.

The portholes are what set this cube apart from every standard play house cube on the market. Red, yellow, and blue acrylic portals in random sizes cover the front panels and the top, bringing pattern, colour, and a sense of joyful architecture to any room the cube enters. The portals also serve a practical function: they let light into the interior and give teachers and caregivers unobstructed visibility of any child inside from multiple angles, without requiring the child to be visible from a single doorway.

Inside, the cosy 40" x 40" interior accommodates a child comfortably for quiet reading, resting, or self-directed activity. A non-ghosting dry-erase marker board and tray is mounted on the interior back wall, giving children a private writing surface for notes, drawings, or imaginative scenarios. Tunnel openings on each side panel provide entry, exit, and additional visibility.

GREENGUARD Gold Certified.

Skills and Benefits of the Whitney Brothers Whitney Plus Porthole Play House Cube

• Sensory Regulation and Calming - The enclosed, lower-stimulation interior with colourful portal light filtering creates a genuinely calming micro-environment within a classroom, supporting self-regulation, emotional reset, and de-escalation for children who benefit from a defined private retreat.
• Imaginative and Creative Play - The interior dry-erase board and private space give children a creative zone for self-directed imaginative scenarios, storytelling, art, and play that is distinct from the shared classroom environment.
• Focus and Independent Reading - The quiet, enclosed interior naturally reduces external distractions and supports sustained individual focus, reading engagement, and independent activity.
• Visual Stimulation and Colour Exploration - The colourful portholes create a visually engaging light play inside the cube as light passes through the red, yellow, and blue acrylic panels, supporting visual attention and colour awareness.
• Gross Motor Skills and Spatial Awareness - Crawling through tunnel openings and manoeuvring within and around the 40" cube develops gross motor coordination, spatial awareness, and body-in-space understanding.
• Literacy and Early Writing - The dry-erase board and tray invite voluntary, self-motivated writing and mark-making in a private, low-stakes context, supporting early literacy development.
