Carpet is the easiest flooring to buy badly. Two samples can look and feel nearly identical in a showroom and be years apart in how long they hold up. The difference is on the back of the sample, in numbers most people never get shown.
Here’s how to read them, so you can walk into any store in South Jersey — including ours — and know what you’re actually looking at.
Start with fiber. It decides almost everything.
| Fiber | Strengths | Trade-offs | Best for |
|---|---|---|---|
| Nylon | The most resilient fiber made. Bounces back from traffic. | Costs the most. Needs stain treatment. | Stairs, hallways, whole-house |
| Triexta | Excellent stain resistance built in, softer feel | Crushes a bit more than nylon over time | Family rooms, kids |
| Polyester / PET | Great color, very stain resistant, budget friendly | Mats down in traffic lanes fastest | Bedrooms, low-traffic rooms |
| Olefin / polypropylene | Fade and moisture resistant, inexpensive | Attracts oily soil, low resilience | Basements, loop and berber styles |
If you only remember one thing: nylon for anywhere people walk a lot, polyester for bedrooms where they don’t. Putting a bargain polyester on a main staircase is the single most common carpet regret we see.
The three numbers on the sample back
- Twist level, sometimes called TTI. How tightly each yarn is twisted, usually a number between 3 and 6. Higher is better, and this is the best single predictor of whether traffic lanes will look matted in three years. Ask for it. Most people never do.
- Density. How closely the yarns are packed. Bend the sample backward — if you can easily see the backing through the fibers, it’s a loose construction and it will show footprints and wear faster.
- Face weight, in ounces per square yard. Roughly how much fiber is there, typically 25 to 60 oz. Useful, but only when comparing the same fiber and style. A heavy polyester is not tougher than a lighter nylon.
Padding is the cheapest real upgrade you can buy
Pad is invisible, so it’s the first thing people cut. It’s also what determines how the carpet feels and how long the carpet lasts, because pad absorbs the impact that would otherwise grind the backing apart.
- For most rooms: 7/16 inch thick rebond at 8-pound density. That’s the standard worth holding out for.
- Thicker is not better. A half-inch pad that’s too soft lets the carpet flex too much and actually shortens its life. Some manufacturers void warranties over it.
- Stairs want a firmer, thinner pad. Too much cushion on a stair edge feels unstable underfoot and wears through at the nose.
- Moisture-barrier pad is worth the upgrade with pets or small kids. It buys you time to clean up an accident before it reaches the subfloor, where the smell actually lives.
Style, and what each one hides
- Textured plush or “trackless”: the everyday workhorse. The varied yarn direction hides vacuum marks and footprints, which matters in a big open room.
- Frieze: tightly twisted, shaggy look, excellent at disguising traffic patterns. Great for busy family spaces.
- Saxony / smooth plush: formal and beautiful, shows every footprint and vacuum line. Lovely in a formal living room nobody uses.
- Loop and berber: durable and clean-looking, but the loops snag. If you have a cat or a dog with long nails, think carefully. One pulled loop runs.
- Patterned loop: hides soil well, but it must be seamed by someone who knows how to match a pattern, and it needs extra material.
If you have pets
- Solution-dyed fiber, where the color goes all the way through, lets you clean spots aggressively without bleaching the color out.
- Cut pile over loop, to avoid snags.
- Moisture-barrier pad, always.
- Mid-tone and multi-tone colors hide far more than either a dark solid or a light solid.
The warranty fine print nobody reads
Most carpet warranties require professional hot-water extraction cleaning every twelve to eighteen months, and they require you to keep the receipts. Vacuuming and renting a machine from the grocery store doesn’t count. If you ever want to make a claim, that paperwork is the claim. Start a folder the week it’s installed.
Stairs and seams are where installation shows
Anyone can lay carpet in a square bedroom. Stairs, especially the pie-shaped winder steps in older Haddon Heights and Collingswood homes, are where craftsmanship is visible. So are seams: a good installer plans seam placement to fall out of the main sightline and away from traffic lanes, and thinks about which direction the pile runs before cutting anything.
When you get a quote, ask where the seams will go and why. An installer who can answer that instantly has already walked the room in their head.
How to test a sample at home
- Look at it in your own room’s light at three different times of day. Carpet color shifts more than any other flooring material.
- Walk on it barefoot. You’ll know in five seconds whether you like it.
- Press your thumb into it hard and release. Good resilience springs back quickly.
- Bend it back to check density.
- Put it next to your furniture and your wall color, not next to the store’s.
