PU Foam Underlay: Turning Leftovers into Premium Comfort

So, what exactly is a PU foam underlay? PU stands for Polyurethane. You probably already know this foam from car seats, airplane cushions, and sofas. But here's the cool part: instead of sending leftover PU foam to landfills, it gets shredded and turned into high-quality carpet underlay. It's a win-win—great for the planet, and an amazing foundation for your floors.When you're shopping for the right underlay, it really comes down to three things: Quality, Thickness, and Density.

1. Quality You Can Trust
Junrui's PU foam underlay meets strict standards. That means you're getting something safe, durable, and built to last.

2. Thickness = Comfort & Warmth
Junrui gives you options, ranging from 3mm all the way up to 20mm. Why does thickness matter? It's all about the "bounce." A thicker underlay gives way more when you step on it, making your floor feel super plush and luxurious. As a bonus, it acts like a cozy blanket for your floor, keeping the heat in and the cold out.

3. Density: Finding Your Perfect Match
Density (measured in kg/m³) basically tells you how firm the underlay is. Do you love that sinking-in, cloud-like feeling, or do you prefer a firmer, more supportive base? Junrui has options for both. We offer densities ranging from 70 kg/m³ to 200 kg/m³. It's totally up to your personal taste, but knowing about density helps you find that sweet spot between softness and long-lasting support.
