Zinus has reinvented the bed frame with this Compack and easy-to-set-up base, engineered for optimum strength and support. It sets up in minutes without tools. The 9 support legs are intelligently recessed so you don’t hit your toes while making the bed. Zinus Compack bed frames are meant to be used with a box spring and mattress set. Worry free 5 year limited warranty. Another comfort innovation from Zinus.
