My first reaction was "OUCH!" when looking at the picture above, but I later came to find out that those oversized pebbles were actually soft and comfortable. Stephanie Marin is the designer behind this high-spirited idea that anyone of any age would enjoy.
The pebbles come in different shapes and sizes depending on what kind of aura you're trying to set. It's fun and restful! I mainly like it because it's nature related which simply gives off a tranquil feel.
