WE'VE GOT ANSWERS

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

Yes. Its ergonomic 7-zone foam and firm coil system foster neutral spine alignment, a key factor in easing chronic back discomfort.

Most modern deep-pocket sheets (fits up to 17") will accommodate the Phantom’s 15" height. If your current linens are standard-depth, upgrading ensures a snug, wrinkle-free fit.

The firm surface resists mid-section sink-in, a quality generally favored by stomach sleepers. Personal comfort still varies, so try it during the 120-night trial.

A tight-top omits the extra plush stitched pillow layer, producing a flatter, firmer sleep surface. Pillow-tops add a cushioned pad for a softer, enveloping feel.

Americanstar typically backs its models with at least a 10-year manufacturer's warranty. Confirm with Cloudy Mattress support before purchase.
