Carpet underlay is a crucial element when laying carpets and transforming a room with new flooring. Underlay should never be deemed an optional extra, as it can increase the lifespan and comfort of your carpets. If you’re unsure which carpet underlay is the best for your home, this guide should help you decide which carpet underlay is best for you.

Choosing the best carpet underlay

There are several different types of carpet underlay, so how do you go about choosing the right product for your new floor? The most important considerations when narrowing down carpet underlay options include the type of room you’re renovating, your budget and the kind of carpet you are putting down.

The most popular examples of carpet underlay include:

• Polyurethane (PU): PU underlay has become increasingly popular in recent years. This type of underlay is made using offcuts and recycled foam, making it an eco-friendly choice. You can buy PU underlay in a range of different thicknesses, and it’s suitable for all rooms.
• Sponge rubber: sponge rubber is a modern version of natural rubber. This underlay provides a luxurious edge, and it is often considered the best underlay for bedrooms and living areas.
• Crumb rubber: crumb rubber is known for its durability, and this makes it an excellent, cost-effective option for high-traffic areas, including corridors, hallways and stairways.
• Felt/crumb rubber: felt and crumb rubber underlay combines the comfort of felt with the longevity of crumb rubber. This is why this product is often considered the best carpet underlay for lounges and sitting rooms.
