mattress topper?

Both Costco here in Canada and in the US sell this 3" Novaform Gel Memory Foam Topper which at moderate cost will turn a rock hard mattress like that in our Coachmen into a soft pillow top that is a dream to sleep on. :B Since our bed was a short queen I extended the bed platform, pulled the mattress forward, and tucked the topper's excess length into the gap between it and the headboard. Pics are in my gallery for anyone interested.
