Carpet Pad Explained: How to Choose the Right Padding for Your OKC Home
· 7 min read · By Floors To You OKC
When people shop for carpet they compare color, texture and fiber, and the pad gets decided in about ten seconds at the end. That is backwards. The pad is what the carpet sits on for its entire life. It decides how the floor feels underfoot, how quiet it is, how long the carpet keeps its look, and, in a house with pets, whether an accident stays a surface problem or becomes a smell. Here is how to choose it properly.
What the pad actually does
A carpet pad is not just there to make the floor softer. Every step flexes the carpet backing, and the pad absorbs that force so the backing and the fibers do not take it all. A good pad is why a mid-range carpet can still look and feel good years later, and an undersized or worn-out pad is one of the quiet reasons a carpet flattens, ripples or wears through in the traffic lanes early.
The pad also insulates, which you notice on a concrete slab in January, and absorbs sound, which you notice upstairs. Our carpet buying guide covers fiber and style; this guide is about what goes underneath.
The main types of carpet pad
Most residential carpet in the metro goes over one of a few pad types. Each has a place.
- ✓Bonded urethane (rebond): foam pieces bonded together, the multicolored pad most people picture. Supportive, widely used, good value
- ✓Prime urethane foam: a single uniform foam. Consistent feel, but quality varies a lot with density
- ✓Memory foam: urethane with a slower, softer feel. Luxurious in bedrooms, less suited to stairs and heavy traffic
- ✓Rubber: dense, durable and supportive, usually at a higher cost
- ✓Fiber or felt: thin and very firm, often used under Berber and other loop carpets that need a firm base
Thickness versus density: the part most people get wrong
The instinct is to buy the thickest pad available, because thick feels plush in the showroom. But density, how much material is packed into the pad, does more for how long a carpet lasts than thickness does. A dense pad supports the backing and springs back. A thick, light pad feels soft for a while, then lets the carpet flex too much, and that flexing is what causes wrinkles, loose seams and early wear.
Many carpet manufacturers set maximum thickness and minimum density requirements for the pad under their carpet, and using a pad outside those requirements can affect the warranty. Industry guidance from the Carpet and Rug Institute is a useful rule of thumb: for most residential cut pile carpet, a pad no thicker than 7/16 inch, and for Berber and thin loop carpets, a thinner, firmer pad no thicker than 3/8 inch. The specific carpet's requirements always win, which is why we match the pad to the carpet rather than the other way round.
Moisture barrier pads: slab homes and pets
A standard pad is open foam. If a pet accident or a spilled drink soaks through the carpet, it keeps going into the pad and, from there, to the subfloor. Once urine reaches the pad it cannot be cleaned out from above, and in an Oklahoma summer the odor comes back every time the humidity rises.
A moisture barrier pad has a film on top that keeps spills in the carpet, where they can be cleaned. It is the pad we recommend in any home with pets, young children, or carpet on a concrete slab, which covers a large share of the houses in the metro. It pairs naturally with the pet-rated SmartStrand, PetProof and LifeProof carpet lines we stock, which carry lifetime stain and odor warranties. Our guide to Oklahoma clay soil and your floors explains why the slab under an OKC home deserves some thought.
Matching the pad to the room
One pad does not have to go everywhere. We choose it room by room, based on how the space is used.
- ✓Stairs → firm and dense, so the nose of each step holds its shape
- ✓Hallways and family rooms → dense and supportive for heavy traffic
- ✓Bedrooms → you can go softer here, within the carpet’s requirements
- ✓Pets, kids or concrete slab → moisture barrier pad
- ✓Berber and loop carpets → thin and firm, never thick and soft
Never reuse the old pad
Reusing the existing pad looks like an easy saving, and it is almost always a mistake. An old pad has already been compressed in the traffic lanes, so the new carpet sits on the dips and wears in the same pattern. It may also hold dust, allergens and whatever pets have left over the years, which comes straight back into the new carpet. Most carpet warranties also expect new pad installed with new carpet.
Our guide to when to replace carpet covers the signs that a carpet, and the pad under it, are finished.
How pad shows up in your quote
A good carpet quote lists the pad by type and thickness, not just "pad included". That is the only way to compare two bids fairly, because the easiest place to shave cost off a carpet job is a thinner, lighter pad that nobody will see until the carpet starts to wear. Our guide to what carpet installation costs in OKC explains what else a complete quote should include.
Pad selection is included with every carpet quote we write. We bring carpet and pad samples to your home, look at the subfloor, ask about pets and how each room is used, and put the pad in writing. Book a free in-home estimate and you can feel the difference between pads on your own floor.
