At Dwell Refine, we understand that not every sleeper is built the same—and for some, nothing feels right unless it’s firm. If you’ve ever been tempted to sleep on the floor just to get the support your body needs, it’s time to meet your match: the Plank Mattress.
Designed for Sleepers Who Crave True Firmness
Inspired by minimalist sleep traditions from Asia—where firm mats and pads have supported generations—the Plank Mattress is a modern reimagining of time-tested wisdom. Built with a flippable design that offers two levels of firmness (firm and ultra-firm), the Plank provides sleepers with a truly customizable, ultra-supportive sleep surface.
-
Top side: Firm
-
Bottom side: Ultra-Firm
Perfect for back and stomach sleepers, or anyone tired of soft mattresses that sag and dip over time.
Chiropractor-Approved Back Support
The American Chiropractic Association has firmly endorsed the Plank for its superior lumbar support. With its ultra-flat, dense construction, the mattress promotes neutral spinal alignment—meaning your back stays aligned, your posture improves, and aches and pains melt away.
Say goodbye to the hammock effect and hello to proper support from head to toe.
Engineered for Better Circulation and Deeper Breathing
The Plank Mattress doesn’t just support your spine—it also encourages better overall health. Its firm, even surface is designed to reduce pressure on your circulatory system, boosting blood flow and even helping you inhale more oxygen as you sleep. The result? You wake up feeling more refreshed, more mobile, and ready to take on the day.
Materials That Make the Difference
Unlike typical soft mattresses that break down over time, the Plank is crafted with high-density foams that deliver unmatched support and durability.
-
Open-cell breathable foam wicks away body heat

Optional GlacioTex™ Cooling Cover adds an instant cool-to-the-touch feel for hot sleepers

Factory-Direct Value Without Compromising Quality

Your spine—and your sleep—will thank you.
