Good to know
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 consists of 3 pieces and all come together 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 (38¼x47") and one fits a mattress for an extendable bed with 1 extension part (38¼x61").
Flexible springs and soft foam
These reversible mattresses grow with your child, just like an extendable bed. Each mattress consists of three parts, one long and two short. The short pieces are easily added to the foot of the bed as your child grows.
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).
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.
