Inflatable Sensory Den — Our Largest Sensory Tent
The Inflatable Sensory Den is our largest sensory tent — a 150 cm cube with room for two children to sit up, read and play, with soft interior lighting and swappable themed jackets. A calm, enclosed den for bedrooms and playrooms.
What is the Inflatable Sensory Den?
Our roomiest sensory space: a 150 cm cube with an interior floor of about 140 × 140 cm, big enough for an adult and a child. It ships with a memory-foam mat, a remote-controlled colour-changing sensory light and a Bluetooth speaker, pops up in seconds and is built to live permanently in a bedroom or classroom corner. Tested to EN71. Free UK delivery over £50.
The Inflatable Sensory Den is the largest tent in the Sensory Spaces range — a proper indoor den with enough head height for a child to sit up comfortably and enough floor for two to share a book, a jigsaw or a quiet half hour apart from the rest of the house. It pops up in under a minute on a sprung frame, so it can be a permanent fixture in a playroom corner or something that appears after school and folds away before tea. Inside, the fabric is muted and the light is soft rather than bright, which is deliberate: a large tent that is visually loud stops being a calm space. Slip a themed jacket over the frame and the same inflatable sensory den becomes a space station, a jungle camp or an underwater world without buying another tent.
Room for two
Our biggest footprint — space for siblings, a friend, or one child plus a generous pile of cushions and books. Head height suits children who have outgrown a toddler-sized tent.
Calm by design
Soft interior lighting and muted fabric keep the inside restful. A big den should feel like a retreat, not a second playroom.
Themes that swap
Every Inflatable Sensory Den takes the full range of tent jackets, so the world inside changes in seconds while the frame stays exactly where it is.
Frequently asked questions
How big is the Inflatable Sensory Den play tent?+
The Inflatable Sensory Den is the largest of our three sizes — comfortably big enough for two children to sit up inside together, with room for cushions and a book basket. Check the product page for the exact dimensions of each model before you clear the corner.
Will an Inflatable Sensory Den fit in a normal bedroom?+
In most standard UK bedrooms, yes — it usually lives in a corner or against the foot of the bed. If you are working with a box room or a shared bedroom, the smaller, foldable Den is the better-sized choice.
How long does the Inflatable Sensory Den take to set up?+
Under a minute. The sprung frame pops open without tools or poles to thread, and it folds back down flat for storage behind a wardrobe or under a bed.
Is the Inflatable Sensory Den suitable for sensory needs?+
Yes. The enclosed shape, muted interior and gentle light are the features occupational therapists commonly recommend for a calm-down corner, and the extra floor space suits children who like to stretch out to regulate.
What age is the Inflatable Sensory Den best for?+
Roughly age 3 and up. Older primary-age children tend to prefer the Inflatable Sensory Den over the smaller sizes because they can sit up fully and share it with a friend.
Can I change the theme later?+
Yes — jackets are sold separately and slip over the same frame, so one Inflatable Sensory Den can be a rocket, a rainforest and a castle across the same year.
