The EnGauge was already a stand-out product that completely changed its niche in the sleep product industry; the EnGauge HYBRID adds even more support to its already great bed frame. The Cal King now has SEVEN legs - they've added a middle support leg! The Engauge Hybrid is both contemporary and sophisticated. It is truly the perfect frame for any mattress set. It's capable of holding over 2000 pounds and will sturdily support your mattress and box spring from head to foot. Tapered legs are crafted from fiberglass-infused resin and will work on carpet or flooring with zero motion transfer. The styling of the EnGauge makes it something of a 'hybrid' between a metal bed frame and a bed. The EnGauge frame is engineered to assemble in seconds without any tools and comes with a lifetime warranty. Time to get rid of your old metal bed frame and upgrade to the Engauge Hybrid by Knickerbocker.
