Product details

The outer cover is easy to remove and is machine washable at 140°F (Hot).

A fixed inner cover increases the fire safety of the mattress and makes it easy to put the outer cover back on after washing. It also prevents children from putting mattress contents in their mouth.

Individually wrapped pocket springs enclosed in a generous layer of pressure-relieving foam which precisely follow your child’s body and provides the support needed for a good, safe sleep.

Protective foam box and felt pad for added comfort and durability.

You can store the extendable parts of the mattress in the included storage bag. This protects them from dust and dirt, and you know that they are fresh when you need them.

On the extension parts there are touch-and-close fastenings that hold them in place when you are making the bed.

A durable mattress that can be used for a longer period of time.

One mattress ‒ three lengths. With the help of the 2 extendable parts, the mattress can grow with your child, from 47" to 61" or 74¾".

  • 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.

    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").

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

OmsintIlliaVery nice5
Mattress for extend a bed works greatMichelleNice firm mattress for the extendabed series of beds; extra mattress pieces came with nice pillow case for storing.5
Comfy!NShoobMy sons bed is comfy enough I can lay down with him for story time! It’s like a regular mattress but it can expand as he grows up! Plan on getting another when my daughter is ready for a bed!5
I love the big piece of the bedANGIL2I love the big part / piece of the bed. Super comfy and we have it on the floor. I’m really picky I love a soft feel mattress but not one I sink into. Medium mattress that moves with my body that feels soft and let me sleep on my back, front, or side. The only bad part is the extension pieces are hard. I wish those pieces had the coils. My knees on those do not sink into the mattress at all making it uncomfortable for a 7 year old child. Also there is no mention that the smaller pieces don’t come with coils. Over all I love the mattresses and we will keep it. It’s so comfy on the floor I never had a mattress that comfy on the floor. We eventually plan to buy an extendable bed but right now we love it as floor cushion For us to lay or sit on while my baby plays in his room.4
NastehaI bought this product two weeks ago I’m so happy bout it5
Comfy!Holly6Great mattress for my toddler! I’ve had to lay with her a few times to get her to sleep in her new bed, it’s so comfortable that I’ve had a hard time not falling asleep next to her!5
Great mattress for toddlerKg0633We bought this for the extendable bed for our 2 yr old. He is sleeping great on it and when I lay down with him I’m comfy too!5


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.


Follows the body perfectly

This 4¾" thick mattress has individually wrapped pocket springs enclosed in a generous layer of soft foam. Since the springs work independently, they closely follow your child's body and provide support in the right places. You can see and feel the care in every detail, from the well-ventilated construction to the durable fabric and detailed stitching. It also has a storage bag for the extension parts. The outer cover can be machine washed at 140°F.
