Beautyrest Black® Series Three 16.25" Medium Pillow Top Mattress at Mattress Overstock

Beautyrest Black® Series Three 16.25" Medium Pillow Top Mattress is a Beautyrest mattress to compare for hybrid coil support, comfort-layer pressure relief, motion transfer, and edge feel. The title gives you the starting point—a Medium feel; a 16.25-inch profile; pillowtop, pillow—but the showroom test is where you learn whether it works for your shoulders, hips, lower back, partner movement, room height, and base setup.

What to compare in person

  • Comfort feel: Lie in your normal sleep position long enough to notice pressure at the shoulder, hip, and lower back.
  • Support: Compare how level your body feels on this model versus nearby firmer, softer, foam, and hybrid options.
  • Height and base fit: Check the mattress profile against your frame, foundation, adjustable base, bedding, and room path.
  • Cooling and materials: Ask what materials are used, then judge the surface feel in person with a protector or sheets in mind.
  • Partner use: Test edge sitting, motion transfer, and how easy it is to move on the mattress.

Questions to bring to the showroom

  • What sleep position and firmness have worked or failed for you?
  • Do you need pressure relief, a cooler surface, stronger edge support, or easier movement?
  • Will this mattress sit on an existing frame, foundation, platform, or adjustable base?
  • What pickup, delivery, setup, and old-mattress removal details apply to your exact address and order?

What makes this mattress different

Medium Pillow Top Comfort

Layers of high-density comfort foams quilted into the medium pillow top surface provide immediate luxurious cushioning and generous pressure relief.

Triple-Stranded Pocketed Coil® Technology

Beautyrest's most advanced individualized support system — three-strand braided coils conform with precision while isolating motion.

Self-Response™ Latex

A natural-responsive latex layer adds instant pressure relief and a buoyant, clean feel that adapts the moment you shift position.

Micro Diamond™ Memory Foam

Diamond-infused memory foam cools and cradles, drawing heat away from the body while conforming to every curve.

Upgraded Sleep Climate™ Cover

An enhanced cooling cover continuously transfers heat away from the sleep surface for consistent temperature control all night.

The support system

Beautyrest builds the feel around pocketed coils first, then tunes it with foam above

Beautyrest hybrids and premium innerspring builds rely on independently wrapped coils to do the heavy support work. That keeps the surface more stable through the middle while preserving easier movement than an all-foam bed.

The comfort foams and cooling package on top change how deeply you settle in, how much pressure relief you get at the shoulders and hips, and how warm the surface feels through the night.

Series Three specifically pairs Beautyrest's triple-stranded coil core with the signature series comfort stack — the practical difference you feel in the showroom is the comfort layer.
