Bonded Urethane: This carpet cushion is also called rebond and is the most popular type of carpet padding sold today.
Long story short - I recommend a synthetic fiber pad. This is not typically what you will find in a retail flooring store, but they can order it for you. Standard, non-memory foam rebond pad would be my second option - try to find a cushion which has a low recycled content.
Most residential carpet requires a pad that is between 3/8 of an inch and 7/16 of an inch thick with a minimum 6-pound density rating. However, low-profile carpets, such as berber, should not use padding that is thicker than 7/16 of an inch (3/8 of an inch is commonly recommended).
The best choice depends on your specific needs and budget. Flat rubber is top-tier for durability and comfort, while options like frothed foam or higher-density rebond offer good performance at more moderate prices. Consider factors like room traffic, desired comfort, and longevity when selecting your carpet padding.
You have the top layer that is your floor covering (Hardwood, Laminate, Vinyl, Carpet, etc.), next you have the underlayment (usually a thin layer of fiber, foam, rubber), below that you have your subfloor (plywood, OSB, concrete), and lastly you have the joists which are the foundation to your floors.
Carpet padding is a type of foam cushion used underneath carpeting. Without the right padding, a new carpet may not lay as well or can be uncomfortable.
Carpet underlayment, also known as carpet padding, is a crucial component in flooring that is placed between the carpet itself and the subfloor. It plays multiple roles, from improving the feel of the carpet underfoot to extending its lifespan by providing support and reducing wear.
On the other hand, a 10 LB carpet pad is very durable but will feel firm underfoot. An 8 LB pad is an excellent middle ground between the two options. While there are many different brands, many 8 LB carpet pads generally offer these similar features: Made from 100% recycled fibers and 100% recyclable.
PU foam underlay
One of the key benefits of PU underlay is that it is made from recycled foam or offcuts, making it a sustainable and environmentally-friendly choice. PU underlay is also lighter and easier to handle than traditional alternatives such as crumb rubber, which is why fitters tend to prefer using it too.
Protecting Your Carpet—on Both Sides
It also protects the top layer of your carpet from furniture indentations and the wear and tear of foot traffic. Without a carpet cushion or padding underneath your carpet, you'll end up with a frayed and worn carpet—on both sides. And you will need to replace it much sooner.
The shock absorbing ability of the carpet padding makes them more comfortable. A quality pad will make the carpet feel softer and cushioned to sit on, lie, and play. The pad also offers thermal insulation, providing an extra layer between the cold floor and carpet to keep the home warmer.
A high-quality PU foam underlay is an excellent choice, as it offers superior cushioning, creating a soft and luxurious feel underfoot. It also provides brilliant insulation, keeping your living room warm and comfortable, especially during colder months.
The Carpet Cushion Council recommends a cushion of at least 5lbs and 3/8-inch thickness for light traffic areas, and 6.5 lbs. and 3/8 inch for heavy traffic areas. These are minimum guidelines and keep in mind the CCC is the trade voice for the carpet cushion (carpet padding) industry.

To face a carpet pad the right way simply lay the pad so the rubber side is up and the softer side is down.

Synthetic Fiber Carpet Pads: These pads are suitable for areas with heavy foot traffic, like commercial spaces. They provide extreme durability and stand up well to wear. Memory Foam Carpet Pads: Similar to memory foam mattresses, these pads are incredibly soft and comfortable.
Rubber. Rubber is a strong material that many prefer for underlayment. It is a popular choice due to its properties like cushioning, sound absorption and moisture resistance.
There is no definitive answer to this question as it depends on a variety of factors, such as the intended use of the carpet and the amount of traffic it will endure. That said, a face weight of over 40 ounces is generally considered to be best for durability.
Carpet padding can last up to 25 years. However, the most popular bonded foam-based carpet padding lasts only around 10 years. Eventually, particularly in high-traffic areas, carpet padding can degrade just like the carpet above.
It has an 8 lb density and is 1/2 in thick.
Underlay or underlayment generally refers to a layer of cushioning made of materials such as sponge rubber, foam, felt, crumb rubber, or recycled plastic; this material is laid beneath carpeting to provide comfort underfoot, to reduce wear on the carpet, and to provide insulation against sound, moisture, and heat.
The right underlayment can make all the difference when it comes to creating an attractive and durable finished flooring surface. However, there are some important factors to consider when choosing underlayment plywood, such as the type, grade, and thickness.
Carpet padding is usually a foam underlayment specifically designed for installation under broadloom carpet. It serves a number of uses such as insulation, acoustics, support, and comfort. Most carpet padding consists of polyurethane foam – the same stuff that's in furniture, mattresses, and even car seats.
