Took a gamble with big on-line purchase... Found rare customer delight!
High value purchase: excellent quality mattress with great pillows included. Opened box and mattress set itself up in a few minutes. First night's sleep was extremely comfortable, like turning a switch and removing pressure points that made my back and shoulders sore with our old mattress. I woke up early the next morning because I got a restful night's sleep for a change. PS - Yogabed should do more to get their name out. I found out about them serendipitously while reading comments on YouTube responding to a complaint about one of their competitors, where some reader said "Yogabeds are cooler than the others because of their materials of construction." That's the one I want!
