Love my new Panda mattress. So comfy and I'm slowly noticing improvements to my back pain. My previous mattress was so light and cheap. This is super heavy and thick - you can really feel the quality. It's also warmer to get into at night which is great in the winter!  I was really impressed by the delivery too. My old one was picked up for free and the delivery men offered to unbox my mattress for me as it's incredibly heavy. As someone who lives on their own I'm so glad as I wouldn't have been able to do it myself!   The only downside is the smell, which does linger for a few days. Also with it being so heavy, I'm actually not sure how I'd take the cover off to wash it. It's probably a two person job!
