I have had my Dormeo Fresh Deluxe Mattress for a month now, why oh why did i not get one before. I suffer with Arthritis and i've never slept so well, just heavenly, supportive yet so soft. Couldn't sleep without it now. The only thing i've done is buy a smaller fitted sheet as it does tend not to stay flat but compared to the comfort i can live with that. I have turned it around every week for 1st four weeks as instucted and this does work. Wouldn't be without it ! Now everybody else in the house wants one !
