Give your child a world of imaginative play — all in one versatile, beautifully designed set. The Monboxy Activity Play Mattress Set in Dark Brown transforms from a sofa to a play gym, sleepover mattress, play tent, spaceship, and so much more. Built for curious minds from 1 to 16 years, it's the gift that truly grows with your child.
Crafted from OEKO-TEX® Standard 100 certified foam, every piece is free from harmful substances — so you can let little ones play freely, knowing their safety is taken care of. The rounded, corner-free design means no sharp edges, and the removable, washable covers make clean-up genuinely easy.

- Base mattress – 170 × 85 × 15 cm, thick foam with removable washable cover
- Flexible mattress – 170 × 85 × 8 cm, thinner and more bendy for creative builds
- Two trapezoidal pillows – 56 × 56 × 31 cm, perfect building blocks for imaginative shapes
- OEKO-TEX® certified foam – safe, human-ecological polyether polyurethane
- Removable & washable covers – designed for real family life
- Easy fold & store – compact storage in small spaces
- Total weight: 15.5 kg
