Stool
Polyurethane (PU) foam is one of the most versatile and widely used materials in stool manufacturing, particularly for padded seat tops. Renowned for its superior comfort, support, and durability, PU foam is an ideal choice for a wide range of stools, including kitchen stools, bar stools, office stools, workbench seating, and medical or laboratory stools. Its ability to conform to the body provides ergonomic support, reducing pressure on the hips and lower back during extended periods of sitting.
Different types of PU foam can be used depending on the application. High-resilience (HR) foam offers firm support and long-lasting bounce, making it perfect for commercial or frequently used stools. Memory foam variants provide pressure relief and contouring comfort, ideal for ergonomic or medical seating. Reticulated or open-cell PU foam can be used for ventilated or quick-dry stool cushions, especially in outdoor or humid environments.
Description
PU foam is lightweight, flexible, and moldable, allowing manufacturers to design stools in various shapes, sizes, and seat thicknesses, catering to both functional and aesthetic requirements. Its resistance to sagging and compression ensures that the stool cushions maintain their shape and support over years of regular use, providing long-term comfort and reliability.
In addition to comfort and durability, PU foam is cost-effective and easy to work with, making it a preferred material for both residential and commercial seating solutions. Whether for home kitchens, bars, offices, workshops, or healthcare facilities, PU foam stool cushions offer a perfect combination of ergonomic support, resilience, and design versatility.
