Every parent knows the struggle: screens everywhere, energy to burn, and not enough space for real play. The Monboxy Activity Play Mattress Set changes all of that — a beautifully designed, multi-use foam play set that turns any room into an adventure, safely and naturally.

Crafted from flexible polyether polyurethane foam with OEKO-TEX® STANDARD 100 certified covers, this set is built for the way children actually play. No sharp corners, no harmful substances — just a soft, safe space where imaginations run wild. Use it as a sofa, an indoor play gym, a sleepover mattress, a play tent, a playhouse, or something entirely your child's own. The rounded shapes and flexible pieces support open-ended, screen-free play from babies all the way through to age 16.

The set folds up neatly for easy storage, and all covers are removable and washable — because real play gets messy, and that's perfectly fine. Available in Deep Green, a rich and calming tone that complements any nursery or playroom.

  • What's included: One base mattress (170×85×15 cm), one flexible mattress (170×85×8 cm), and two trapezoidal shape pillows (56×56×31 cm)
  • Safe, certified materials: OEKO-TEX® STANDARD 100 certified fabric and foam — tested for harmful substances, safe for all ages
  • Endless play possibilities: Sofa, play gym, sleepover mattress, tent, playhouse, spaceship — limited only by imagination
  • Gross motor & developmental skills: Builds balance, coordination, and problem-solving through active, open-ended play
  • Easy storage & care: Folds flat for minimal footprint; removable, washable covers for effortless cleaning
  • Ages 0–16: Grows with your child — from tummy time to teen sleepovers
  • Weight: 15.5 kg — sturdy yet manageable for parents to reposition

Give your child the gift of real, unstructured play. Shop the Monboxy Activity Play Mattress Set at Nestling today.
