Which is the best PU foam underlay for carpet?
At Carpet Underlay Shop, we offer a comprehensive range of luxury foam underlay from some of the best underlay brands, including Wilsons Plushwalk, Cloud 9, and Tredaire. Manufactured to the highest possible standard and offering an exceptional level of quality, these are all available for very competitive prices.
Ranging from 6mm to 12mm, our PU foam underlay products come in a variety of thicknesses, with different densities and TOG ratings to suit different needs. Ideally, to ensure the best possible finish, you should invest in an underlay that is as thick and dense as possible – but not so thick that it’s difficult to fit or so dense that it’s hard to walk on.
For the most supportive foam underlayer, we would recommend Plushwalk 12mm Carpet Underlay. Made from ‘bounce-back’ memory foam, it’s soft and comfortable, boasts a range of impressive properties, and can be used in all rooms throughout the home. For stairs and thicker carpets, we also offer Plushwalk 10mm Carpet Underlay.

Frequently Asked Questions
This type of foam is a popular choice for supportive yet soft underlay because it offers a wide range of benefits, including:
- Extra comfort – Even thinner carpets feel comfortable and soft to walk on with polyurethane carpet pads, making rooms feel both cosy and luxurious.
- Great insulation – Foam is an effective insulator, so these underlays tend to have higher TOG ratings and help to maintain comfortable temperatures.
- Sound reduction – This insulation also creates a soundproofing effect, helping to reduce the transmission of impact and airborne noise between floors.
- Easy handling – As a lightweight material, foam is also easier to transport, cut, and fit, making installation easier for both DIY and professional projects.
- Sustainability – Often containing a high percentage of recycled foam (such as sofa cushion or mattress offcuts), this is an eco-friendly underlay option.
These are just some of the advantages that make PU foam one of the most popular carpet underlay types for homes across the UK.
While a thick foam underlay can provide excellent compression recovery for several years, it’s best to install this type of underlay in spaces where comfort is the main concern.
With less foot traffic to wear the flooring and underlay down, you can enjoy the plush feeling underfoot for much longer, which is why polyurethane foam and memory foam are excellent options for bedroom carpet underlay or living room carpet underlay. Your bedroom and lounge are meant for relaxing, and soft underlay is sure to help with that!
Of course, there are some settings where foam carpet underlay isn’t the best choice, such as underfloor heating systems or places with extremely heavy traffic or furniture.
However, we still have a range of products to suit higher-traffic zones like stairs and hallways, such as thinner and higher-density PU underlay options. These include designs that are specifically manufactured for use on stairs, such as ExtraStep 6mm, RichStep 9mm, and ExtraStep 11mm from the Carpenter Underlay range.
A standard PU foam underlay or sumptuous memory foam underlay may not be suitable for commercial premises, as it can wear out very quickly with constant heavy foot traffic.
This doesn’t mean that commercial properties can’t enjoy plush-feeling carpets, though!
From office buildings to hotels and beyond, our high-density foam underlay products can be used in commercial and contract installations – including Cloud 9 Silver Lining 6mm, Wilsons ToughStep 9mm, Cloud 9 Super Contract 10mm, and Tredaire Citra HD 11mm.
We also supply a selection of flame-retardant foam underlay products, including Cloud 9 Flame Retardant 8, Tredaire Flamecheck 4 and 6, and Tredaire FR7 – some of which have an International Maritime Organization (IMO) rating that makes them suitable for use in maritime vessels and offshore installations.
