Is the Beautyrest Black Series Four Hybrid worth $5,599?

It is a top-tier luxury hybrid with pocketed coils, foam and latex, so the price buys support and durability. Whether it is worth it depends on how much you value a plush, conforming feel over a cheaper hybrid.

How does it compare with the Black Series Three?

The Series Four sits higher in the Black line with a thicker 16-inch build and more premium comfort layers. Expect a plusher feel and a higher price than the Series Three.

What sheets fit a 16-inch mattress?

You need deep-pocket sheets rated for at least 16 inches, ideally 17 to 18 inches to allow for a topper. Standard sheets will likely pull off the corners.

Does it work with an adjustable base?

Yes. Hybrid mattresses with pocketed coils generally bend for adjustable bases, but check Beautyrest's warranty terms for the specific base you use.

When is the best time to buy it?

Major mattress sales around Memorial Day, Labor Day and Black Friday tend to bring the deepest discounts. At $5,599 at Raymour & Flanigan as of November 7, 2026, it is at full luxury pricing.
