Product Overview

To begin with, the Serta Perfect Sleeper Cascade Bluff Plush Hybrid offers cloud-like soft comfort from a CoolFeel® Plus cover that feels cool on contact. Next, EverCool® Supreme gel memory foam and additional pressure-relieving soft foam layers cradle shoulders and hips, making it the best 14.5-inch plush mattress for side sleepers.

 Beneath these layers, a five-zone gel-foam band reinforces the lumbar area for targeted spinal alignment, while 920 Density Q4™ individually wrapped coil hybrid support absorbs partner movement to deliver advanced motion isolation for couples. Excel-inspired edge reinforcement lets you sit or stretch to the rim without roll-off, and the 14.5-inch profile creates a luxuriously tall look. 

Finally, you can buy Serta Cascade Bluff Plush online with free shipping in the USA, fast two-week dispatch, and easy financing, so upgrading to a luxury plush hybrid mattress king or queen is simple while the current sale lasts.
