RIWI Buildit is a US-based children's toy brand founded in 2017 by two engineers who grew up building caves from upholstery and towers from blocks — and couldn't find a single toy that was both giant, versatile, and affordable enough for home use. So they built one themselves. Today, with over 2 million building blocks delivered worldwide, RIWI has become the go-to brand for XXL foam building blocks in homes, schools, daycares, and therapy centers across the globe.

The flagship product, the RIWI Giant Building Blocks, is made from a proprietary high-quality polyurethane foam formula — independently tested and certified to meet strict US toy safety standards (ASTM), machine-washable, and built to last through years of active play. The catalog also includes the 2-in-1 Play Couch & Storage Kit (fits 24 blocks and doubles as a kids' couch), Velour Covers and Faux Leather Covers for extra durability in institutional settings, and the XXL Storage Bag for easy clean-up and transport.

Over 95% of surveyed families say RIWI is their child's favorite toy and the highlight of every play session — a figure backed by more than 50,000 happy kids since launch.
