The carpet gets the attention. The pad underneath changes how that carpet feels, how it wears, and how the floor sounds. Express Carpet and Hardwood has been selling and installing carpet in Anaheim and across Orange County since 1986, and the pad is part of the conversation every time.
This is a plain-English guide to what the pad does, how thickness differs from density, and what to ask before you buy.
What the pad actually does
Carpet pad, sometimes called cushion, sits between the carpet and the subfloor. It does a few jobs at once:
- It changes how the floor feels underfoot.
- It supports the carpet yarn so foot traffic does not grind the backing against a hard subfloor.
- It takes up small irregularities in the floor below.
- It softens sound, which matters in upstairs rooms and over a living area.
A beautiful carpet on the wrong pad can feel limp, or it can wear in a path sooner than you expected. Choosing the carpet and the pad together is the point of seeing them in the showroom. Our carpet page covers the yarn. This post covers what goes under it.
Thickness and density are different things
Thickness is how tall the pad is. Density is how much material is packed into that thickness.
A thick pad that is loosely made can feel soft for a week and then collapse under a hallway. A thinner pad that is denser can feel firmer and hold its shape longer. Asking only "how thick is it?" misses half of the story. Ask for both, and ask which rooms that combination is meant for.
We will not quote a single thickness for every house. Stairs, a bedroom and a concrete slab are different floors.
The common types of pad
These are the types you are likely to hear named. They are categories, not a ranking.
- Bonded foam (rebond). Scraps of foam bonded into a sheet. It is a common residential pad. Density varies a lot from one product to the next, so the name alone is not enough. Ask what density you are being offered.
- Prime foam and frothed foam. Made as a foam sheet rather than from bonded scraps. Feel and firmness depend on the specific product.
- Rubber. Often firmer. Some people choose it where they want a solid step, including on stairs. It is heavier than most foam.
- Fiber. A felt-like pad. It can feel firm and is sometimes used where a soft foam would be too spongy.
- Moisture-barrier pads. A pad with a layer meant to slow moisture moving up from a concrete slab. The slab still has to be suitable for carpet. The barrier is not a substitute for looking at the floor underneath.
If a name is unfamiliar, ask to see a sample and to stand on it with the carpet you are considering. The combination is what you will live with.
Matching the pad to the room
- Stairs, hallways and living rooms. These take the traffic. A firmer, denser pad usually supports the carpet better than a very soft one. On stairs, too much softness at the nose of the step is something we plan around. See carpet for stairs and hallways.
- Bedrooms. Comfort underfoot matters more here, and the traffic is lighter, so a softer feel is often appropriate.
- Pets and kids. Spills and rough play are harder on a pad that stays damp or that bottoms out. Tell us about the pets before we pick.
- Upstairs. Sound traveling to the room below is part of the choice. A pad is one of the things that changes that.
- Concrete slab. Many Anaheim homes sit on slab. Ask whether the pad should include a moisture barrier, and what the slab itself needs before carpet goes down.
One pad for the whole house is not always the right plan. It is reasonable to use a firmer pad in the hall and a more comfortable one in the bedrooms, as long as the height difference at the doorway is handled in the install.
Questions to ask about the pad
Bring these to the showroom, or ask them when we measure:
- What type of pad is this, in plain words?
- How thick is it, and what is the density?
- Is this the pad you would use on stairs, or only in a bedroom?
- Does this room sit on a concrete slab, and does the pad need a moisture barrier?
- How will this pad change the feel of the carpet I already liked?
- Is the pad included in the written number for material, prep and labor?
If the answer to the last one is unclear, ask for the pad to be listed on its own line. What a flooring estimate should include covers the rest of that page.
Feel the difference in person
A spec sheet cannot tell you whether you like the step. At the Anaheim showroom you can compare carpets at full size and talk through fiber and pad before anything is measured. Start with carpet, then visit the showroom.
