If you need a soft play set that can keep a whole group of children busy, our Castle & Cubes Soft Play Set is the one. It combines our 11-piece foam castle with six large cuboid blocks: 17 pieces in total for climbing, building and imaginative play.
What's in the set?
- 11 castle foam blocks: arches, steps, ramps and towers.
- 6 large cuboid blocks for walls, seats, steps and platforms.
- Wipe-clean eco-leather covers.
- High-density T-21 upholstery foam for firm, safe support.
Suitable from 12 months.
Why add the cubes?
- Bigger builds: the cuboids extend the castle with walls, towers and platforms.
- Group play: 17 pieces means several children can build at once without squabbling.
- Extra seating: the cubes double as toddler seats for story time.
- Obstacle courses: mix steps, ramps and cubes into a circuit across the room.

Built for nurseries, childminders and play centres
The wipe-clean eco-leather and firm foam make this set hard-wearing enough for daily use in settings. See our guides to soft play for nurseries and schools and equipment for a soft play hire business.
