What makes soft sand?

Sand with rounder grains usually feels softer, because the grains slide past each other more easily. Smaller grains also don't produce the pinprick feeling of individual grains pressing into your skin.

What is sandstone made of?

Sandstone is a type of rock made from sediment — a sedimentary rock. The sediment particles are clasts, or pieces, of minerals and fragments of rock, thus sandstone is a clastic sedimentary rock. It is composed mostly of sand particles, which are of medium size; therefore, sandstone is a medium-grained clastic sedimentary rock. More precisely, sand is between 1/16 millimeter and 2 mm in size (silt is finer and gravel is coarser). The sand grains that makeup sandstone are aptly referred to as framework grains.
