I am so glad I bought this bed. I purchased a medium based on the previous reviews, I needed something firm and the medium is just the right firmness for me. I can actually sleep in this bed and not sleep on an incline when my husband is next to me. I have been needing a firmer bed for years, but I am now 7 months pregnant and could not take the sleepless nights any longer. My husband loves this bed too, he sleeps so deep that he has begun to snore. I have been getting the best nights sleep since I purchased this, I only wish I had purchased the 11 inch rather than the 9 inch since we have a platform bed and the bed is a little low. No regrets with this purchase though, we are very happy with it - especially since we were not able to test it out before we purchased it.
