A good night's sleep is always a fundamental consideration, but especially on holiday.
When on a working trip or a break, we sleep in a different bed and environment.
If we sleep little or badly we can feel the effects all through the next day.
It follows that the bed we sleep in must meet all of the requirements to ensure good rest.
By bed, we mean the combination of support structure + mattress, which must be able to bear the weight of the average body.
This load bearing capacity must be the same for the entire surface area of the bed and must not change over time.
Given these requirements, the choice of materials must be precise.
The pillow is another matter: everyone has their own preferences. A second pillow is always available, also in bigger sizes.
