2 weeks in - I've ditched the bed, carpet , throw - duvet cover , ............using the old head board with some standoffs for my head with an additional pillow . no going back.
reasons : bad back + sleep apnea , always crush these modern lightweight pillows and my chest crushes my neck.
apparently a soft mattress leads to a stiff body & a hard surface manipulates / pummels you - relaxing muscles.
secondary bonus this is the floor, as adults we lose touch with the floor it's just a place you look down at.
if you wouldn't ever sleep on the floor , take an hour off the sofa in an evening and sit on the floor..
