This isn't medium it s a plush mattress, the mattress is not distributed evenly, the corners of the mattress is lifted  , I weigh 130 lb and Im already sinking in!!!! this would not be suitable for 2 people. Not recommend for anyone with back issues what so ever!! I gave it a few weeks to gather a honest review. I will buy a mattress topper. FYI This mattress company Is the same company as Molblly .
