Advanced Technology

The Americanstar Capella 8 Inch Medium Mattress proves that great sleep doesn’t require towering thickness and staggering budgets.

Its two-inch Cool Gel Memory Foam comfort layer uses Amstar-Aero™ gel beads to whisk away warmth for steadier body temperature (so no more night sweats).

Beneath, six inches of high-density Amstar-Flex™ foam create balanced push-back. This allows your hips and shoulders to stay level, encouraging optimal spinal alignment all night.

A soft, breathable knit cover and anti-slip base boost airflow and keep the bed planted on any solid foundation.

Because of this thoughtfully layered design, sleepers feel a cloud-like medium comfort feel that cushions pressure points yet resists sag.

Lastly, you can rest easy with an Americanstar limited warranty, a 120-night risk-free sleep trial, free USA-wide delivery, and our Cloudy Price Promise.

HAVE QUESTIONS?

WE'VE GOT ANSWERS

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

Yes. Its medium firmness cradles shoulders and hips while the dense core keeps the spine straight. Ideal for most side-sleeping bodies.

The Amstar-Aero™ gel layer actively draws excess heat away, while the breathable cover lets air circulate, so most users report a neutral, comfortable temperature.

It rates “medium” on the industry scale (right in the middle between plush and firm), giving a balanced blend of softness and support.

Certainly. Its low-profile 8" height meets safety rail guidelines for standard bunks, and the no-slip base helps it stay put.

No. Place it on any solid platform, slatted frame (3" slat gaps or less), or an adjustable base. A box spring is optional for added height, not support.
