Berlin Hybrid Mattress - Twin/Single Mattress (38 x 74) / Medium (5 / 10)

The Berlin natural mattress from Berkeley Ergonomics is truly unique. Featuring a honeycomb-nested interactive European pocketed coil, this design has a long history of comfort and durability. From head to toe, the Berlin spring system alternates between a taller, larger-diameter spring and a shorter, smaller-diameter spring. The alternating rows of taller and shorter pocket coils adjust well to all body types and distribute pressure in a superior fashion to the typical method of pocket coil zoning. The bi-level spring system in this mattress is also incredibly well suited for use on electric adjustable bases. Atop this wonderful spring system is a layer of pure 100% natural Vita Talalay latex for breathable, long-lasting comfort. Finishing off the mattress is 100% organic cotton ticking and 100% Plein-Air French sheep's wool, providing optimal temperature and humidity regulation. All materials are certified to be free of harmful chemicals by the OEKO-TEX® Standard 100 , ensuring a clean and healthy sleep environment. Our Berlin mattress is simply one of the very best value-for-money mattresses available anywhere in Canada under $3,000 in queen size. When compared to mainstream mass-production mattresses, it's easy to see how much thought was given to the design of this mattress. It might not be a super thick pillow top, yet because of the highly elastic nature of this design, it is every bit as cradling and comfortable without resorting to using lower-performance polyurethane foam. Finish off your Berkeley Ergonomics mattress with a Formesse Bella Donna fitted sheet. Made in Germany, these special fitted sheets are stretch-knit and super breathable. They work in perfect harmony with the high-performance elastic materials found in all BE mattresses.
