Advanced Technology

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.

HAVE QUESTIONS?

WE'VE GOT ANSWERS

Designed for deep comfort and better rest, so you wake up refreshed and ready for the day

Yes. Plush foams and zoned coils cushion shoulders and hips while supporting the spine, which most side sleepers appreciate.

Choose fitted sheets with at least a 16-inch pocket depth to keep corners secure.

Both share the same hybrid build, but Plush uses softer foams for a gentle feel, while Firm substitutes denser layers for extra lift suited to back and stomach sleepers.

No. Any solid platform, slatted base with gaps under three inches, bunkie board, or adjustable foundation provides proper support; a box spring is optional.

Serta backs the Cascade Bluff with a limited manufacturer's warranty shown at checkout. Cloudy Mattress adds a 120-day trial so you can confirm comfort at home before committing.
