The idea to couple pad is very interesting, especially when you are sleeping twice. But the velcro are not on whole lenght and for my pads it works just by forcing a little bit. Just two are not enough to avoid the pads have a hole. I put them at head and at waist because I think it's better to have a hole at feet... But I would prefer to not have any hole...
