Mattress Firmness 8.5 out of 10 - Very Firm

Mattress Elasticity 10 out of 10 - Extremely Elastic

The Koala mattress solves a whole host of unique challenges, and we couldn't be more proud of the result. When natural latex is manufactured, there is always a small percentage of finished latex that will have visual imperfections. While these visually imperfect cores are perfectly fine from a performance perspective, they are normally rejected.

Our belief was that perhaps we could apply the same approach of the "imperfect fruit and vegetable campaign." These "B-grade" visually imperfect latex cores are from Radium Foam BV in The Netherlands. The pricing is fantastic. An equivalent "A-grade" mattress would cost approximately $700-900 more.

These are perfect mattresses for children and sleepers up to 150 lbs. Because visually imperfect latex cores are uncommon and the imperfections are generally confined to small portions of an otherwise perfectly poured core, the finished mattresses are only available in twin size.

Made with the same ingredients found in all Berkeley Ergonomic mattresses, rest assured your child is sleeping on a mattress free of chemicals, flame retardants and PBDE's. We use 100% Plein-Air sheep's wool from France as an all-natural fire barrier, with the added benefit of exceptional breathability and temperature regulation.

Handcrafted one at a time, made from entirely European-sourced components and free of harmful materials. What's not to like?

Koala mattresses are produced in batches and are available while supplies last. Availability is entirely dependent on the number of visually imperfect cores available from Radium at any given time. The Mattress & Sleep Company will do our best to keep this page updated with the most accurate availability details.

Suggested Foundations

We recommend a sturdy, well-ventilated slat foundation for all mattresses. Berkeley Ergonomics offer three choices. The highest performing foundation is the Berkeley Ergonomics suspension foundation.

Suspension foundations are superior to rigid bases as they absorb energy, reducing pressure points while also providing for greatly improved ergonomic alignment and support. They'll even extend the life of your mattress.

Berkeley also offer a 2 ⅜" slat frame which will fit in most platform beds, allowing you to benefit from the suspension slats and their enhanced ergonomics when a platform bed would not normally fit a box spring.

All Berkeley Ergonomics mattresses are 100% compatible with electric adjustable beds.

All wood used in these three foundations comes from sustainable PEFC and FSC certified sources in Canada and Germany.

We Recommend Formesse Fitted Sheets

The highest performing fitted sheet for your Berkeley Ergonomics mattress is a Formesse Bella Donna fitted sheet. Your BE mattress features a knit organic cotton fabric outer covering, which is very stretchy and elastic. Typical sheets are woven (ie: sateen or percale), which can result in excess surface tension. Formesse sheets, Made in Germany, are different. They are stretch-knit, just like the Berkeley mattress fabric. This combination results in the most elastic, highest performing sleep surface possible today.

Knit fabrics are also more breathable than woven fabrics, which results in better temperature and humidity regulation.
