The cover is woven from organic European linen, layered over seven layers of pure flax tow. Nothing synthetic touches your baby, just natural fiber that breathes with every nap.

Gaps around a mattress are a real safety concern, so we make each one to the exact dimensions of your cradle or bassinet. If your size is not listed, our team will build one just for you.

Flax tow keeps its shape and firmness instead of compressing like foam over time. Each mattress is hand-tufted with linen thread so the filling stays evenly distributed night after night.
Getting the size and firmness right matters more than most parents expect, so here is what to check before you buy.
- Measure your cradle first: Measure the inside base of your cradle or bassinet in inches, length, width, and depth, before choosing a size. A snug fit with no gaps along the sides is what you are aiming for.
- Check the shape: Rectangular and oval bassinets need different mattress shapes, so confirm which one your frame requires before ordering.
- Prioritize firmness: A firm, flat surface is safer for a sleeping baby than a soft or plush one, so avoid anything that sinks under light pressure.
- Think about what touches baby's skin: Look for covers made from natural, breathable fiber rather than synthetic blends, especially if your baby has sensitive skin or tends to run warm.
- Ask about custom sizing: If your cradle is an odd or discontinued size, ask the maker directly whether they offer custom dimensions instead of settling for a mattress that does not quite fit.
How do I know which size to order?
Measure the inside length, width, and depth of your cradle or bassinet in inches and match it to our size chart. If your measurements fall between sizes or your bassinet is not listed, email us at hello@wholesomelinen.com and we will make a custom size for you.
Is this mattress firm enough for safe sleep?
Yes, the seven layers of flax tow are designed to stay firm and supportive rather than soft or sink in. The flax keeps its shape over time instead of compressing like foam can.
What is the mattress cover made from?
The cover is 100% organic European linen, chosen for its breathability and natural resistance to allergens, bacteria, and dust mites. There are no synthetic fabrics or chemical treatments used.
Does it contain any chemicals or flame retardants?
No, there are no flame retardants, glues, bleaches, dyes, vinyl, PVC, phthalates, foam, or latex in this mattress. The linen and flax combination naturally resists fire without added chemical treatments.
What if my bassinet size is not listed?
Reach out to hello@wholesomelinen.com with your measurements and the team will create a custom mattress to fit your specific cradle or bassinet.
What is your shipping and return policy?
Orders ship from a US warehouse with free shipping on orders over $100, and you have 30 days to return the mattress if it does not work out. Our team is available by email if you have questions before or after you order.
