I purchased this mattress with high hopes, as other reviews were very positive. I was looking forward to portable and comfortable mattress as I do overnight elder care and have to sleep on floor. Although I purchase this several months ago, I’ve only recently used it for 2 weeks. I have to say I’m very disappointed in it. After this short time of use the mattress already has impressions in it. It is soft and not firm as in description. I am 5’9” and weigh 145 lbs. I use the mattress on a padded carpeted floor. I would not recommend this item as the one I purchased has failed in 2 weeks of use. I now feel like I’m sleeping in a hammock.
