Earlier used to have the Kurlon orthopedic mattress and it was firm and hard but after few years it began to sag and break inside as probably it was a coir mattress. If you are looking for an orthopedic mattress it is better you check that out in an outlet physically as mostly what you see in online is something and what you get is something. Also I have slept in a wake-fit mattress in a friends house which is a firm and hard mattress you can check out. It is a good mattress.Thanks i am looking for a firm to very firm mattress for the other bed... Any suggestions?
