Carpet pads are cushioning materials placed underneath carpets to enhance comfort and durability. They help absorb impact, reduce noise, and provide insulation, making walking on carpets more pleasant. Available in various materials like foam, rubber, and felt, carpet pads can also extend the life of the carpet by preventing wear and tear. Choosing the right carpet pad is essential for optimal performance. A thicker pad generally offers more cushioning, while a denser pad provides better support. Proper installation of carpet pads can improve the overall appearance and feel of a room, making it a worthwhile investment for any home or office.
