Save 25% on a bed when you add this mattress to your order

Enjoy first‑class comfort every night with the Sealy Posturepedic Altair Plush Motion, the standout model in the Elevate collection. Built with AlignSupport® springs, it senses your shape as you settle in and delivers deep, consistent support for healthier alignment and lasting durability. The system is paired with FlexKey™ edge support, giving you greater stability and allowing you to sleep right up to the edge while also working seamlessly with adjustable bases.

For comfort, the Altair Plush Motion layers MemorySense® ComfortCore® for targeted pressure relief, a double layer of InfiniLux™ premium foam for resilient softness, and graphite‑infused latex for breathability and freshness. These layers work together to ease tension, enhance comfort and maintain a cool, hygienic sleep environment.

The surface is finished with SmarTex® climate‑regulating fabric and ProShield® anti‑allergen technology—expertly woven textiles that look as good as they feel. Complete with a breathable air‑mesh border exclusive to Elevate Ultra, the mattress promotes better airflow throughout the night.

Handmade in Britain and backed by a 7‑year guarantee, the Altair Plush Motion combines premium materials, innovative support and long‑lasting quality for a truly luxurious sleep experience.
