What determines what firmness we prefer in a mattress?
If I sleep on a hard mattress, my back kills me, but I know others who have similar back problems and prefer a hard mattress. And, I know people without ailments that prefer either one. It doesn't seem to be tied to health conditions or weight.
It depends on what the problems are- that was my point. I slept on a hard mattress over the weekend and it aggravated my lower back, which morphed into sciatic pain and numbness/ tingling. I lived on ibuprofen and could barely sleep because of the pain. I have the same problem any time I sleep on a hard mattress. I was so glad to come home to my softer one. After a night on that, I felt much better, but I'm still a bit sore.
I had a disc collapse and rupture, the sciatica was agonising and chronic. For six years I couldn't straighten my left knee (if I did I either fainted or vomited from the pain - or on one eminently forgettable occasion, both), existed on opioids and couldn't work or drive a car. After a week of needing my better half's help simply to get out of bed (it was that or soil myself), we just had to buy a firmer mattress. I couldn't get enough leverage on the soft one without the use of my back or left leg.
depends on the person and how it feels, i cant have a nnattress around at all thanks to those bugs nny building had, ive had to sleep on an airbed since the end of april cause of getting rid of nny bed and couch, i cant have a nnattress around thanks to thenn, so i got an airbed on purpose so they cant nest in plastic, its not as connfortable sonnetinnes but i dont have nnuch choice, dont want anything with cushions around, never replaced the couch either
