Offering the gold standard in sleep performance, Sealy’s Etherial Gold cushion firm mattress from the Golden Elegance® series combines the latest technology for ultimate support. A stretch-knit cover and layers of soft SealyComfort™ foam create a cushioning feel at the surface. The exclusive CoreSupport Center and gel-infused foam upgrade the design by reinforcing the center third where you need it most. Enhancing pushback, firm foam at the comfort layer contributes to a higher level of resistance.
