Question

It is more comfortable to sit on a bed than on a fence.

Answer 1

Explanation:

because bed is more spongy than fence

Answer 2

Pressure = Force/Area

Area and Pressure are inversely proportional.

As area decreases (as in the case of a fence as it has a sharp edge), Pressure increases (on our body) so we feel uncomfortable sitting on a fence.

Whereas a bed has larger area so as the area increases pressure on or body decreases so we can sit cofortably on a bed
