Serta PerfectcomfortX Tux Smooth Top Plush

The Serta Perfect Comfort X Tux is a 14" plush mattress — the second-softest option in the Perfect Comfort X lineup — built around a 5-zone coil and memory foam system with graphite-infused Perfect Conform™ Memory Foam and dedicated cooling technology.

It’s designed for sleepers who want deep, cushioned comfort without losing structure underneath. The 5 ZoneActive™ Design combines zoned coils, micro coils, and contouring memory foam so the mattress supports where your body needs it most — softer under the shoulders and hips, firmer through the lower back — while graphite-infused Perfect Conform™ Memory Foam pulls heat away from the body instead of trapping it against you.

A Good Fit If You’re:

• A side sleeper who wants real cushioning at the shoulders and hips instead of pressure points
• On the lighter side and find firmer mattresses feel unyielding rather than supportive
• Someone who runs warm at night and wants a plush feel without the "heat trap" memory foam is known for
• Looking to upgrade from an older pillow-top to something with zoned, targeted support underneath the softness
• Sharing a bed and want the coils to isolate movement even in a plush build

What Stands Out on the Tux

• Micro coils layered under the memory foam add a responsive bounce that pure foam mattresses don’t have
• Graphite infusion in the memory foam actively redistributes body heat instead of just sitting on the surface
• Zoned coil support means the plush feel doesn’t come at the cost of proper spinal alignment
• Full-body alignment is engineered in, not just cushioned — this isn’t a mattress that "sinks" evenly

Deep Comfort, Real Structure

Plush mattresses often trade support for softness — the Tux is built to avoid that trade-off. The 5-zone coil system keeps your spine supported even as the top layers cushion pressure points, so you get the hugging feel of a plush bed without waking up with an aching lower back. It’s the version of "soft" built for people who actually sleep on their side most of the night, not just people who like the way a mattress feels in a showroom.
