These Kidswaw PlayBoxes look like a great idea, as they are truly multifunctional bits of furniture. They are a toy box, and a bench seat, and a play area all in one, and Asda have them reduced from £66 to £48, which is a good £10 cheaper than elsewhere.
Asda have two different styles - a Play Kitchen and a Race Track. They are made from sturdy MDF and painted, and would be a great space saving idea in a child's bedroom or play area. Size wise they are 60cm x 60cm x 39cm, which is a decent size for a toy box and for a small play kitchen.
If neither of these designs is quite what you are looking for then the JCB version* is also on offer, but is a little more at £50.
Delivery is from £2.95, or you can click and collect for free from Asda stores.
