The Arabella series which features three choices of comfort (Plush, Firm and Pillowtop) was inspired by the luxury and elegance of Europe’s top rated hotels. Each bed in this series has 2” of gel foams quilted into top of the mattress to help dissipate heat and provide a luxurious sleeping surface. Below the sleeping surface is 2” of 5-zone Convoluted Serene™ foam, which will provide individualized support for the sleeper while working perfectly with the 789 Quantum Edge Coil system. All of the beds in this series can be used on an adjustable base.
