Where do you get that? According to Newton's 2nd law, F = m a, the force of gravity (weight) is the product of mass times the gravitational acceleration. The hardness of a surface has nothing to do with either the mass or the gravity and hence it cannot change the weight.

Basically , our weight has nothing to do with the surface
no matter how hard the surface is our weight is still cnstant unless we weigh ourselves in different areas such as north pole and equator
weighing ourselves at north pole would give heavier weight than in equator because in equator force is needed to supply the centripetal force , so we can rotate thus our weight is reduced

The surface on which you are standing has no effect on your weight. But if you use a weighing scale to weigh yourself on different surfaces, you may notice a slight dfference, but it should be the other way round. i.e. the reading may be more on a hard surface (which will be the correct rading).
That is because soft surface may absorb some of the force due to your weight.

The harder the surface, the greater the antigravity field.
