The Americanstar Capella 10 Inch Plush Mattress wraps you in a cloud-soft hug while still keeping your spine aligned. 

This mattress’s feel lands on the softer side of medium-plush. Perfect for side sleepers or anyone who craves that sink-in comfort without losing support. 

Because of its first layer of cooling gel-infused memory foam, body heat is whisked away so you stay comfortably regulated all night. 

Beneath that, open-cell foam technology branded as Amstar-Flex lets fresh air circulate, while Amstar-Aero Max gel foam molds to every curve for contouring pressure point relief. 

Together, these layers deliver a weightless, cloud-like plush sleep feel and minimize partner disturbance. 

Lastly, the mattress ships free, and carries the manufacturer’s warranty. Giving you complete peace of mind when purchasing.

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

Yes. Its plush feel and pressure-relieving gel foams cushion the shoulders and hips that typically bear weight in a side-sleeping posture.

The top layer of cooling gel-infused memory foam and breathable open-cell core are engineered to disperse heat, so most sleepers report a comfortably neutral temperature.

Capella rates as plush (around a 4 of 10 on the typical mattress firmness scale), giving a soft initial hug with supportive underlying foam.

After unboxing, allow 24-48 hours for the Capella to reach its full 10-inch profile; slight foam odors are normal and will dissipate in a well-ventilated room.

Yes. All-foam Americanstar models are flexible enough to articulate with most standard adjustable foundations. Just ensure the base provides solid, evenly spaced slats or a deck surface for proper support.
