We've been told by every single person who has slept in our guest room that it was one of the best night's sleep they'd had...ever! Why? We have a super comfy bed with an air controlled mattress, topped with a memory foam topper, then covered in a hypo-allergenic mattress pad that helps control temperature. We top it off with 400-ct, 100% cotton sheets and a hypo-allergenic duvet. At night, the room is cool (2 fans and cool a/c) and oh, so dark! Makes for a deliciously deep sleep!!
