Advanced Technology

The Bluesky 11” Firm Mattress by Americanstar is made for sleepers who crave steady, dependable support but want it at an affordable price point.

Thanks to its firm hybrid design (yes, this is a firm hybrid mattress by Americanstar), you’ll notice an immediate lift that keeps your spine neutrally aligned.

Next, a layer of Amstar-Cool™ gel memory foam gently moulds to curves, dispersing heat for optimal pressure point relief, while the soft bamboo cover stays fresh and airy.

Beneath, individually wrapped coils anchored by built-in lumbar zoning supply orthopedic spinal alignment support and curb partner ripple with motion isolation coil technology.

Because of this balanced pairing of contour and stability, back sleepers (and anyone chasing restorative, deep sleep comfort) wake up without any stiffness.

In the end, practical perks seal the deal: a 120-night comfort trial, free shipping in the USA, and the option to buy an Americanstar Bluesky mattress online today with financing through Affirm.

Of Cooling
Comfort

A soft bamboo cover promotes airflow across the surface. It helps keep the sleep environment cool and fresh.

A contouring foam layer cushions pressure points for added comfort. Gel infusion helps draw heat away from the body.

A dense foam layer provides a stable surface feel. It supports proper weight distribution and prevents excessive sink.

Individually wrapped coils adapt to body movement and weight. A built-in lumbar zone reinforces lower back support and reduces motion transfer.

WE'VE GOT ANSWERS

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

Its firm feel plus lumbar-zoned coils are designed to keep the spine’s natural curve, which many back-pain sufferers find helpful. However, always consult a medical professional for specific conditions.

The Bluesky is rated “Firm,” offering a sturdy, supportive surface with slight cushioning at the top.

Generally, any rigid, flat base (slats no more than 3″ apart, platform frame, or adjustable base) works well.

Pocket-coil hybrids typically flex fine on modern adjustable bases, but confirm with the base manufacturer if in doubt.
