The Froli Modular Sleep System consists of a grid of high-tech plastic “spring elements,” which together work like a standard box spring mattress. Each spring, measuring roughly 5×5 inches, is made of a thermoplastic elastomer, a high-tech material that combines the flexibility of rubber with the strength of a durable, space-age plastic. This material offers a memory-like effect for precise flexing while returning the spring to its original shape at rest. The Froli provides three spacing options to set the overall firmness of the bed, two sets of color coded springs that provide a different level of firmness—dark blue, firm; light blue, soft—plus a set of red tension clips shaped like four-leaf clovers that provide even more firmness in certain areas if needed. It’s a clever and ingenious design, unrivaled by anything else in today’s market. Price is for two boxes.
