When shopping for new carpet, most people understandably focus on the carpet itself, things like the colour, texture, thickness, and overall appearance. But what many homeowners don’t realise is that one of the most important decisions sits underneath the carpet entirely – the underlay.

It might not be the most glamorous part of your flooring project (it’s a bit like prepping to decorate!), but choosing the right underlay can make a huge difference to how your carpet feels, performs, and lasts over time.

In fact, good prep under your flooring can completely change the comfort of a room and the longevity of your carpet.

What does underlay actually do?

Put simply, it’s the cushioning layer installed between your carpet and the floor beneath it.  Its job is to support the carpet and absorb impact from foot traffic.  A good underlay will help to improve comfort underfoot, help to insulate your home (so important with the rising energy costs) and extend the lifespan of your carpet.

Imagine your bed without its mattress – well that’s a bit like that.  Without proper support, even the best carpet won’t perform at its best or last as long as it should.

Why good underlay makes carpet feel better

One of the first things customers notice with quality underlay is comfort.

Walking across carpet fitted with proper underlay feels so much softer, warmer and generally more luxurious.  This is especially noticeable in bedrooms, living rooms and particularly in high traffic areas like stairs and landings.

The difference can genuinely surprise people during showroom demonstrations.

It can save money long-term

Some homeowners are tempted to reduce costs by choosing cheaper underlay but this really is false economy.

Poor products underneath your carpet means it’ll wear faster because the fibres will flatten more quickly.  You’ll visibly see high traffic areas deteriorate sooner.  Quality underlay help protect your investment by reducing strain on the carpet above.

Better insulation = Lower energy loss

Underlay also acts as insulation and a good one helps retain warmth, making rooms feel cosier, especially during the winter months.  This can help reduce heat loss, improve comfort and support energy efficiency.

It’s one of the easiest ways to make a room feel noticeably warmer.

Noise reduction benefits

If you have a busy household, with children running around and hard flooring elsewhere in your house, it will help reduce noise transfer.  This is also important if you live in flat or apartments and in bedrooms and upstairs rooms.

Different types of underlay explained

As with carpets, there are lots of different options:

Foam: Soft, comfortable, and popular for bedrooms and lounges.

Rubber: Durable and supportive which is ideal for heavy foot traffic.

Felt: Traditional option offering warmth and cushioning.

Specialist: Designed for underfloor heating, sound reduction or heavy wear areas

Our showroom teams can explain the differences and recommend what works best for your home.

The right underlay depends on the room

Different rooms need different support.  For example, bedrooms often prioritise comfort, hallways need durability and your stairs require stability and wear resistance.

Choosing the right combination of carpet and underlay helps create the best overall result.
