This is the reason why a Fatboy lounge bag might be priced slightly higher than an ordinary beanbag. The foam has a much longer life span than ordinary Styrofoam that you might find in the local market. This foam has a much better ‘bounce back’ when you squeeze it, so the lifespan of a Fatboy is much longer compared to ordinary beanbags.
