The simple reason that could be ascribed to this question is that the best rated hotel mattress is specifically made with the purpose of being more fire resistant and is also a fire retardant in many cases. It is usually prescribed for commercial establishments where the numbers of occupants are more.
The number varies from place to place and it could be anything of 6 occupants and more. Further, one more reason why this mattress is called that way may be because it is designed to cater to the needs of different types, sizes and needs of customers.
On the other hand, home mattresses are usually used by the same groups of people and hence, they are designed to cater to those specific needs. Hotel mattresses usually come in different shapes, sizes and designs and hence, they are given this specific name.
Further, a hotel memory foam mattress is usually made from coarser materials though the outside fillings are from high quality materials. This is because the coarser materials are known to last long and that is how a hotel collection mattress is supposed to be.
In fact, it would not be out of place to mention there that even many homes are now buying a hotel full size mattresses because of the sheer elegance, comfort and the various designs and shapes in which they come.
If you are the on who is keen about buying a hotel natural mattress for your home, you certainly should spend a lot of time on the internet where there is a lot of information available on them. You would do well to read some reviews about various mattress models and brands which have been made only for use in hotels, clubs and motels.
Further it is also important to keep in mind that the mattresses should be made from such materials that it is easy to clean them without much difficulty. They should preferably be made from materials which make it possible to be dry cleaned.
At the end of the day, the main difference however between a home mattress and a hotel brand mattress is with regard to its meeting fire safety norms. Other differences at best could be described as cosmetic and negligible to say the least.
