The best carpet underlays for living rooms and lounges

The Best Underlays For Living Room Carpets

Living rooms are made for lounging in our PJs, spending time with the family and entertaining our favourite people, which is why a cosy, inviting space matters.

In this guide, we explore how choosing the right carpet underlay can add comfort and warmth to your lounge, making the heart of your home the comfiest spot in the house. 

Why you need carpet underlay in a living room

Underlay improves the feel, function and longevity of your living room carpet. Here’s why it should be at the top of your list:

Comfort: In a room where we spend so much time, it needs to be comfy. A quality carpet underlay provides an extra layer of cushioning and smooths out an uneven subfloor, offering a softer underfoot experience.

Warmth: An underlay with a high tog rating helps to retain heat in the room, keeping your lounge cosy and energy-efficient. 

Noise reduction: The most effective carpet underlays have sound-absorbing properties that dampen impact and airborne sounds – such as conversations, TV noise, and footsteps – reducing the overall noise level in the room, as well as the transmission of sound through the floor and into other rooms.

Durability: Living rooms tend to be one of the higher traffic areas in the house, so the thicker the underlay, the longer your carpet will last and keep its shape.

Living room carpet underlay checklist: what to look for

Selecting the right carpet underlay involves finding the right balance of comfort, insulation, noise reduction and durability for your specific needs. Here’s what to consider when shopping:

  1. For optimal underfoot comfort, choose a PU foam underlay with a minimum thickness of 10mm.
  2. For colder living rooms or those with unheated subfloors, choose a tog rating of at least 3.00 for a cosy, well-insulated space.
  3. Select a product with an impact sound reduction rating of 40 dB+ for effective noise dampening.
  4. In lounges with heavy foot traffic, choose a high-density underlay for extra carpet support and better bouncebackability.
