The matress is comfortable however it doesn't fit snugly inside our double bed frame where our previous double mattress fitted perfectly and there are gaps all the way around.   Because the matress isn't very thick in depth it doesn't fit inside a standard double fitted sheet and slips out.   This is really annoying because the sheet gathers up while you're sleeping on it and has to be adjusted and tightened every day.  Would I buy a Dormeo again?  Based on this experience probably not.
