The Dual King is the perfect approach for a couple to accommodate the requirements of one of the individuals and also serve the needs of their relationship in a desirable fashion.

A Hi-Low Twin can be united with another Hi-Low bed or with either of the less expensive adjustable hospital beds listed for maximum comfort, affordability and a wonderful night's sleep.
