  • Fits all our extendable beds.

    We recommend LEN fitted sheets made of cotton jersey for your child’s mattress.

    Wash the cover inside out with the zipper closed.

    The short pieces are easily added to the foot of the bed as your child grows.

    This mattress comprises 3 pieces and all come in the same package.

    The extension parts of the mattress do not have springs since it is primarily shoulders and hips that need pressure relief, not legs.

    LEN fitted sheet is available in 2 sizes: One fits a mattress for an extendable bed without extension parts (80x130 cm) and one fits a mattress for an extendable bed with 1 extension part (80x165 cm).

What is foam?

Foam is excellent as upholstery in seating and mattresses since it provides good comfort and can relieve pressure by moulding to the body. Depending on the properties and feel you’re looking for, there are several qualities to choose from, like high-resilience foam and memory foam. The raw material for foam was previously based entirely on virgin fossil materials. But today, together with our suppliers, we’ve begun developing a material that is renewable and recycled.


Flexible springs and soft foam

The longer part of this three-piece, 12 cm 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 cover can be removed and machine washed at 60°C.
