Am constantly bombarded by adverts for these on FB, but am seriously tempted to try one of these mattress in a box things. They've all got 100 day trials, which seem genuine. Otty in particular looks good, but am also looking at Simba as that you can at least try in John Lewis. Has anyone tried one of these before I recklessly take the plunge? grin
