The maximum weight for which one bed of the mattress is designed is, in fact, the maximum weight of a person who can regularly sleep on a mattress for a long period of time without the risk of "overloading" and spoiling the product. Of course, this parameter cannot be exceeded; however, when purchasing a mattress, you should also make sure that the selected model has a certain weight reserve — at least 10 kg. This is due not only to the fact that the mattress can be used by different people (and the weight of permanent owners can also change), but also to the uneven load that occurs during use. The fact is that manufacturers can specify this parameter per sleeper, i.e. practically immobile person. In fact, the matter is not limited only to sleep — as a result, the mattress may experience a load greater than the calculated one, even in cases where the weight of the person on it does not exceed the claimed characteristics.
