Fits our small spaceAsh151We love this bed because it fits our growing daughter's small room perfectly. Finding fitted sheets isn't as easy as normal sized beds, but Ikea has some good options for basic fitted sheets for the medium size bed!5


Flexible springs and soft foam

The longer part of this three-piece, 4¾" thick mattress consists of flexible springs enclosed with soft foam. The construction means that the mattress keeps its shape longer, allows air to circulate and provides comfortable support for your child. The two short parts consist of pressure relieving foam. The outer cover can be removed and machine washed at 140°F (Hot).
