If you are in a dash or don’t want to read all the reviews about which is the best carpet underlay then based on safety, price and features we recommend the Plushwalk Carpet Underlay as the best buy this year.

There are plenty of comfy carpet choices out there.  However, in many cases, you might want to give yourself a little bit of extra cushioning underfoot.  Carpet underlay, for example, is a great way to ensure softer, warmer walkways, along with better insulation and protection from shock.  All in all, a carpet with underlay is likely to be soft enough for you to sleep on!

But what is it that makes a good quality underlay?  When buying carpet underlay for the first time, what are some of the features and factors you should be looking into?  Underlay is available in a wide variety of cuts and thicknesses. What’s more, different manufacturers will offer different types of floor cushioning.  If it’s your first time in setting up a new carpet, how do you know which choices are likely to work best for you?

We’ve made sure to take a look around the web for the best carpet underlay UK homes can buy.  There are different types of underlay for different needs. Some will stop carpets from sliding around.  Others, meanwhile, will give you added warmth. Think about your own comfort and everyday needs. What do you need your carpet underlay to offer you?  It’s time to check out a few top picks that are already getting plenty of interest online.

In this article, we are going to review the following carpet underlay choices:

What to Look For in Good Quality Carpet Underlay

Of course, your needs for carpet underlay may well differ to other people’s.  You might be looking for added comfort and warmth, while others may just want the shock absorption.  What’s more, anti-sliding could be one of the main reasons why you are shopping around. Therefore, always be ready to look closely at the factors that separate leading brands and choices.  Here are the main features you should be looking at when considering which carpet underlay is best for you.

Focus on Thickness

If comfort and warmth matters to you, then you should be thinking about thickness.  The thicker the underlay, then naturally, the comfier and warmer it is likely to be underfoot.  However, you may not always find thick underlay to be easy to set up. What’s more, if you’re looking for specialised underlay, i.e. non-slip gripping, you’re not always going to get a particularly thick pile.

Ease of Fitting

There are plenty of great underlay options which are easy for you to set up on your own.  But what if you have no idea where to start? Can you find a good quality underlay that can be fitted by an expert in your area?  

Plenty of online options are likely to be great for DIY.  However, if you’re a complete novice in the world of carpet fitting, you might want to speak to a specialist outright.

Types of Underlay

Of course, you should also think about the types of underlay you can invest in.  You can generally find underlay in PU foam, which tends to be the leading choice for soundproofing and comfort.  It is also often the most affordable choice for the average homeowner. However, you can also buy underlay in memory foam, which is amazingly comfy, as well as felt and rubber.  As mentioned, certain specialist underlay systems will avoid general materials altogether. Therefore, it’s worth looking at the wider market and seeing what other buyers have to say.

What’s best for you may not be best for the general public!  Can you get out to a carpet retailer and try underlay on for size?  If not, be ready to trust online reviewers, as well as to watch a few video reviews for the full lowdown.

Quality of Manufacture

Of course, a big factor to look for is manufacturing quality.  The better the quality of your underlay, the longer it is going to last.  Therefore, make sure to look for a company that is well-regarded, and options which have plenty of solid reviews.  There is a danger that you will find low quality underlay online, even through Amazon, meaning it’s always worth taking cheaper listings with a pinch of salt.  In the case of which underlay you should buy online, it’s probably good to invest a little more money for the quality you receive.

Best Amazon Choice for Underlay:  Plushwalk Carpet Underlay – 12mm – 15m2 = (11m x 1.37m)

Best Gripper Underlay:  DIY Doctor 2X Gripper Rolls, 11,600 cm² , Ultimate Extra Thick 400gsm (Formerly Medipaq)

As mentioned above, not all underlay options are built to give warmth or cushioning.  This DIY Doctor option, for example, is specifically useful to stop slippage. You can use it on rugs, small carpets and more besides.

One of the most appealing features of this type of underlay is the fact that it is both impressively thick as well as very easy to cut and shape.  You can use it to stick to most surfaces across the home. However, if you’re looking for traditional underlay, this isn’t going to be your ideal choice.


  • 400GSM gripper underlay should help to fix rugs and carpets for plenty of time to come.
  • It’s one of the easiest underlay types to set up through DIY, as it’s easy to cut through and lay.
  • It has a variety of colours and applications, meaning you can even use it on tables and desks if you wish.


  • Not the all-round underlay option most people will be looking for.

At 8mm thick, it should give you plenty of bounce, cushion and noise protection.  It’s also one of the easiest underlay choices to fit on your own, available in a range of different sizes and cuts.


  • 8mm of thickness should be more than enough cushion for most homes.
  • Ready to lay and fix, it has a user-friendly design, and customer service on standby.

Best Value Underlay:  10mm Thick PU Carpet Underlay Rolls

When considering which underlay is right for your carpet, you’ll likely be thinking about costs.  As with the other T&A option above, this underlay system is environmentally friendly, though it actually offers a bit more in the way of thickness.

Again, you can ask for free samples if you’re really unsure what you’re looking for.  10mm in thickness is a great amount of cushion for the price you can expect to pay here!  You also benefit from local support and guidance.


  • Environmentally-friendly manufacture and non-toxic underlay, perfect for young families and homes with pets.
  • Nice and thick at 10mm, and wide enough for many rooms at 5x5m.
  • Free sample availability is a very nice touch for first-time buyers.
