I saw a video on YouTube of a guy selling a mattress. I bought it and I'm happy. The key concept was that it's a compartmentalized mattress so if the top layer develops the characteristic u-shape where you always lay at night, it can be replaced for 1/5 the cost of a new mattress and it's essentially brand new. I had the Purple before. It was nice but it only lasted about 2 years. I'll post a link here. https://youtu.be/5xihmJhS-as https://youtu.be/YAwm_gPbG4o
