Online Mattress r Cheaper so i think people attract more to it. Most of the online Mattress those r Orthopedic r just selling the High Density Foam mattress instead of BONDED Foam which is the Proper orth Foam. So i always recommended to Buy mattress off line so before u buy u may feel the Comfort. Buying a mattress with just few Details & cheaper price is waste of Money.

I am manufacturers of mattress, and I sussest you, PU foam mattresses are not good for health, but under age of 30 you can use it, after 30 years persons should be used Pocketed spring with memory foam, coir sandwiches mattress with pu foam, Latex foam mattress, and 100% Rebonded foam mattresses is good for health because Rebonded foam mattress have using high density of foam it will support to spine on straight body.

I think particularly suggest any name of mattress brand will not good for business, but I can suggest you that approximately all mattresses brands using 100% Rebonded foam mattress, which you want afford or comfortable you can buy it but remember choose only 100% Rebonded foam mattress not sandwich mattress. I am using Relaxwell brand, and model is Eco bond. But that time this brand is purchased by my father for me and till now I am using approximately 15 yrs complitted. Rebonded foam always using all brands for makes orthopedic, and spine support without Rebonded foam using can not make orthopedic mattress. All companies are using this foam.
