Foam soft play block sets for toddlers and young children — large, modular foam shapes that children can stack, climb, rearrange and build with to create their own indoor play environments. Our biggest range, spanning castle sets, explorer sets, adventurer sets, rainbow sets, pyramid sets, iglu houses, cube sets, wheel sets and more.

Why choose foam soft play block sets?

Open-ended play that grows with your child

Unlike fixed play structures, foam block sets reconfigure endlessly. Children aged 1 to 5 can climb, build, knock down and rebuild — creating a new play environment every time without any new equipment needed.

Safe, certified foam construction

All block sets use high-density PE foam that holds its shape through years of active play. EN-71 certified, non-toxic, BPA-free and fire retardant. Safe for children from 12 months.

Wide colour range

From neutral whites and bouclé creams to bold multicolours and pastels — there's a block set colourway to suit every home and every taste.

Soft play block sets: frequently asked questions

What age are foam soft play blocks suitable for?

Most of our block sets are designed for children from 12 months, when they start pulling up, climbing and stepping. Low sets like the Little Crawler and Mini Climbie suit babies from around 6 months, while larger castle and cube sets keep children busy up to 5 years and beyond as their play becomes more imaginative.

Are foam blocks safe for babies and toddlers?

Yes. Our blocks are made from high-density foam with no hard edges or sharp corners, so bumps and tumbles are cushioned. They're tested to EN71 toy safety standards and are BPA and phthalate free. As with all play equipment, young children should be supervised.

How much space does a soft play block set need?

A typical 11-piece castle set fits comfortably in about 2 square metres when built, and the pieces can be stacked neatly against a wall when you need the floor back. Compact sets like the Pyramid or Wheel sets work well in smaller rooms.

How do I clean foam soft play blocks?

Eco leather covers simply wipe clean with a damp cloth and mild soap. For fabric covers such as bouclé, spot clean as needed. See our soft play cleaning guide for step-by-step tips.

Can I mix and match different block sets?

Yes. Many of our shapes are made to similar sizes, so you can add a cube set, wheel set or extra slide to an existing castle set and build bigger obstacle courses as your child grows.

Are your block sets suitable for nurseries and soft play hire?

Yes. Our wipe-clean sets are popular with nurseries, childminders and hire businesses, and larger sets like the Mega Castle and Soft Play Party Set are built for busy commercial settings.
