Made for mattresses up to 16" thick. Almost all hybrid, newer foam, and pillowtop mattresses fall in this range. 100% Eucalyptus Lyocell – made from trees grown on sustainably managed, biodiverse farms. Absurdly soft – and they get softer after every wash (for real). Sleep better no matter the weather – eucalyptus lyocell keeps you in the ideal temperature zone all night. Hypoallergenic – eucalyptus lyocell is skin-credible, aka dermatologist recommended. Zero static – eucalyptus lyocell doesn’t attract dust, dirt, or hair (pet, human or otherwise). Zero pesticides – eucalyptus trees are naturally insect-repellent; meanwhile, cotton uses an estimated 16-24% of the world's insecticides, including bee-killing neonics. Thoughtfully designed in Denver – “Bottom Left Corner” tag takes the guesswork out of making the bed; 360° elastic with extra deep pockets provides a super secure fit.
