Who the Serta Tux suits

The Serta Tux is a good fit for side sleepers who want real cushioning at the shoulder and hip, lighter sleepers who find firm beds unyielding, hot sleepers who want plush without a heat-trapping pad, and anyone upgrading from an old pillow top. Back and stomach sleepers usually want the Pixel.

How the Serta Tux compares

The Pixel is the same smooth top in firm. The Relax is the plush super pillow top if you want the pad. The Perfect Sleeper Wondrous is the lower-priced plush smooth top with three zones. Serta's Canadian lines, from the entry up: Perfect Day (boxed, 800 StablEdge coils), Classic, Perfect Sleeper (three-zone coils, Cool Twist gel foam), PerfectComfort X (five-zone coils with micro coils and graphite memory foam), and the all-foam iComfort and latex iComfort Pro.

Questions we get asked about the Serta Tux

Who is the Serta Tux best for?

Side sleepers who want real cushioning at the shoulder and hip, lighter sleepers who find firm beds unyielding, hot sleepers who want plush without a heat-trapping pad, and anyone upgrading from an old pillow top. Back and stomach sleepers usually want the Pixel.

Is the Serta Tux a good mattress?

Yes. The Serta Tux is from Serta's Perfect Comfort X line, Smooth Top, built on 5 ZoneActive™ Design: 5 zoned coils with contouring memory foam plus micro coils, with a 10-year warranty and made in Canada with domestic and imported parts. We sell it at 25 to 70% below regular retail, nobody here works on commission, and you're welcome to lie on it in the store before you decide.

What is a smooth top?

No quilted pad: the graphite memory foam sits right under the cover, so you feel it directly, with micro coils and zoned coils underneath.

Is it good for side sleepers?

Yes. Plush at the surface with support through the hips.

Does it sleep hot?

Less than a pillow top: no pad, graphite in the foam, coils moving air underneath.

What is the difference from the Relax?

The Relax adds a thick super pillow top and an inch of height; the Tux is the plush feel without the pad.
