We've taken aspects of our most popular mattress and pillow top – the medium-firm Euro and medium-soft Sculpted Pillow Top – and created an even cushier, all-in-one, luxurious new mattress. The Lassen certified organic mattress represents Lifekind’s plushest introduction to the line. It offers springiness without springs, and a comfort level we have never offered before. Ideal for side sleepers, especially, the Lassen — with its sculpted surface unique-density natural rubber core and 3.5" pillow top – provides a super-soft feel. (Warning: This mattress may make you want to turn off your snooze alarm one time too many!) The Lassen is a medium-plush 10.5” sculpted-surface pillow-top mattress made with GOLS-certified organic rubber latex. It starts with a 6” core of supportive medium-firm latex covered in our signature certified organic cotton-and-wool quilting. A removable two-sided pillow top (3 1/2” deep) — also made of GOLS-certified organic rubber latex — is then placed on the mattress. The pillow top is made with two surface options: our exclusive sculpted surface on one side, and a flat surface on the other. This provides sleepers with maximum comfort and flexibility. The pillow top is then covered with our signature certified organic stretch knit cotton-and-wool quilting.
