i did a ton of research to get just the right one for my teenager.  when 1st taken out of the box after it takes shape it does seem like its going to be a bit chincy but by day 2 all of the foam was fully fluffed.  the 1st week we did rotate it every day to help keep the foam from wearing on one side more; now she flips it each week.  This thing is amazing; she has slept on it more than once and i even took a nap on it after work one day!!! Everyone in my house now wants one!!!
