i was so excited when it came! at first it was interesting feel. took some time to get used to sleeping on foam, but after four months. it started to sag in the middle and it gave me the worst backache. Even my pups didn't want to sleep on it. I now have a extremely heavy memory foam. That even good will didnt want, cause its too heavy to carry.
I am writing this review 2 years after purchasing this mattress. My sleep has improved considerably and I will never go back to spring mattresses! This mattress is firm but like many reviewers have stated, it becomes soft and contours to your body as you lay. I would recommend buying the metal bed frame too.
This is the third one we have purchased for three different beds. The first one was purchased 7 years ago and is as comfortable now as it was when we first purchased it. The mattress takes about a week to get used to if you have been using something different. It does retain warmth during the night, bu that hasn't been a problem even in the warmest months.
