The cover is woven from organic European linen and filled with pure flax tow, so there is nothing synthetic touching your baby's skin. It is biodegradable and sustainable from start to finish, a mattress you can feel good about choosing.

Linen dries almost twice as fast as cotton, so it pulls moisture away from your baby's skin and helps prevent rashes and overheating. Your baby stays cooler and drier through naps and nighttime sleep.

There are no flame retardants, glues, dyes, or foams in this mattress. The linen and flax combination acts as a natural fire retardant on its own, so you are not introducing fireproofing chemicals into your baby's sleep space.
Getting the size and firmness right matters as much as the materials, so here is what to check before you buy.
- Measure your basket first: Measure the inside length, width, and depth of your Moses basket or bassinet before ordering. Oval shapes vary more than rectangular ones, so exact measurements matter.
- Look for a snug, gap-free fit: A mattress that fits tightly against the sides of the basket, with no gaps, reduces the risk of your baby's limbs slipping into a space. If your size is not listed, ask about a custom option rather than forcing a loose fit.
- Consider firmness, not just softness: A firm surface is important for a young baby's sleep space, so avoid mattresses that feel plush or overly soft when you press on them.
- Check what the cover is made from: Natural fiber covers like organic linen tend to breathe better and wick moisture more effectively than synthetic covers. This can make a real difference for a baby who sleeps warm.
- Ask about care instructions: Natural fiber mattresses often have specific cleaning guidance, so check whether the cover is removable or spot clean only before you buy.
Will this mattress fit my specific bassinet or Moses basket?
It is made in several oval sizes to fit popular bassinets and Moses baskets, including Delta, Badger Basket, UPPAbaby, Tadpoles, Restoration Hardware, Moba, and Bilia. If your basket falls outside the standard sizes, you can contact the brand directly to request a custom size.
Is the flax filling firm enough for safe sleep?
Yes, the flax tow filling is designed to provide firm support, which is the kind of surface recommended for a young baby's sleep space. It does not compress into a soft or plush feel like foam can.
Does this mattress contain any flame retardant chemicals?
No, there are no added flame retardant chemicals in this mattress. The combination of organic linen and flax tow naturally resists fire without needing those chemicals added.
How do I clean the mattress cover?
The linen cover is designed to be breathable and naturally antibacterial, which helps it stay fresher between cleanings. For specific washing instructions, it is best to check the care label or contact the brand directly.
What if I order the wrong size or change my mind?
Orders ship from a US warehouse and you have 30 days to return the mattress if it does not work out. Our customer support team is happy to help you double check sizing before you order.
Is this mattress hypoallergenic for sensitive skin?
Yes, the organic linen cover and flax filling are naturally hypoallergenic, antibacterial, and resistant to dust mites, which can be helpful for babies with sensitive skin.
