SleepEZ’s Select Sleep Natural Latex Mattress offers lifetime flexibility and comfort. Due to its extreme durability and flexibility the natural latex mattress will not sag after long use and does not transmit movement, meaning you won’t disturb your sleeping partner. Our Select Sleep Natural Latex Mattress can be customized to match your firmness preference in soft, medium, firm or extra firm. Over the life of your mattress, you can rearrange or replace these layers in your own home to achieve a different firmness, based on your changing needs.
