Memory foam is one of the best inventions to come out of the space programme, and today the best beds all make use of this dense foam that springs back to its original shape every time. This luxury mattress combines it with a second, deeper layer of SuperFlex support foam for an even more comfortable night�s sleep.The ritual of turning the mattress every few months is a pain in the back � sometimes literally! The Apollo Memory is a single-sided mattress so there�s no need to turn or flip. It�s also much more lightweight than the average sprung mattress, so if you need to lift it to tuck those sheets in or to rotate it head-to-toe occasionally, it�s much easier.The Apollo Memory mattress comes vacuum-packed and rolled up, so it�s easy for just one person to get it upstairs and into the bedroom without trying to heave a huge double mattress around that bend in the staircase! Once you�ve got it into the bedroom, simply unbox it, take off the vacuum packaging, and let it unroll. Leave for up to 48 hours and it�s ready to use with no compromise on firmness.
