5 Types of Sofa Cushions – Fillings and Material Guide

1. Foam

Foam, which comes in a variety of densities, is by far the most popular stuffing option for sofa cushions.

  • Low-density foam cushions are softer but wear out more quickly unless they are of very good quality.
  • High-density foam filling can seem firm at first, but it breaks in with use and more weight.
  • Then there’s the supportive and body-hugging memory foam. Those with muscle and joint pain can benefit greatly from it.
  • Finally, HR foam is durable and won’t lose its shape over time. It has a potential lifespan of 14 years or more.

In this group, you can choose between molded foam, all-foam, spring down, or a blend of the two. There is a wide variety of density and type of foam available, including memory foam. The level of firmness and gentleness necessary for each application varies.

Molded Foam

Cushions made from molded foam are very firm. There is zero upkeep required on your part. Multiple layers of fabric, including duck and Dacron feather, protect the inner foam.

The foam is typically hard at first, but breaks in to a more comfortable texture over time. Molded foam has a variety of outer shells to provide an extra layer of protection while maintaining a comfortable level of softness.


A solid seat and few fabric wrinkles are provided by an all-foam cushion. This cushion is made with a high-density foam core covered by a more comfortable layer of “egg crate” foam.

Next, a layer of polyester fiber is used to wrap everything up. The cotton down-proof ticking that encases these layers is highly water resistant. The feathers can’t poke through this cloth.

Spring Down

When it comes to comfortable foam cushions, spring down is a close second to all-foam. The thick fiber polyester covering the coiled spring core inside the foam box provides excellent support.

A down-proof cover, stuffed with polyester fiber and down, encases the several layers. The coiled springs provide support, and the down padding makes it comfortable to lie on.

Blendown or Down Plush

One of the most plush and high-end foam cushions is Blendown. It comprises a thick coating of polyester fiber covering a thin foam core.

A thicker layer made of polyester-fiber and down surrounds the first two layers. The cushion’s down cover and thin foam center create a pillowlike experience. The softness of the cushion means that it quickly loses its original form and needs frequent fluffing.

2. Hollow-Fill Fiber

These sofa cushions are so plush and comfortable that they’re ideal for a midday nap. They’re not great for long stretches of sleeping or lounging, but they’re wonderful for couches that are utilized for such purposes.

The cushions are so plush that they will bear your impression when you get up. Since they tend to soften, rotating them on a regular basis will provide uniform wear on both surfaces.

3. Feather

One of the best things about feather pillows is that they can be customized to fit your exact needs. Depending on your preference for a firmer or softer seat, you can adjust the amount of feathers. The greater the number of feathers in a cushion, the greater the need to plump them to prevent them from clumping together.

4. Polyester

Couch cushions made of polyester are your greatest bet if you’re watching your pennies. They come in a variety of densities, and you may get them for a low price.

But the filling does spread out really quickly. Smooth, long-lasting, and bouncy are just some of the qualities that characterize soft polyester.

Ply-a soft polyester is a kind of squishy, limp filler.

It looks and feels like real down, but is made out of polyester. It’s more affordable and suitable for those with feather allergies.

The small fiber balls in a cluster-polyester cushion ensure that it lasts for a very long time.

5. Batting

Last but not least, there’s batting, which acts as both insulation and padding. It is available in two different weights: 42.4 and 25.5 ounces.

Most batting is constructed from either polyester, wool, or cotton. Cotton batting has a tendency to poke through couch cushions.

It is recommended to pick a polyester-cotton blend for more frequently used sofas. Wool batting comes in both layer and needle forms. The latter is utilized on springs since it is so durable. The earlier type of filling deteriorates rapidly and is not recommended for use in couches used for lounging.

How Can I Make My Couch Cushions Firmer?

Option 1. Fix the filler

  • Take the couch cushions off and throw off their covers.
  • Check the cushions’ filling to see if it’s something you can replace or fluff, and then take the necessary steps.
  • Cushions on a sagging couch can be made to feel like new by giving them a good fluffing.
  • Since polyester fiberfill doesn’t compress as easily as other crafting materials, it’s a preferable choice to utilize it in place of crumbled or filthy sofa fillings.
  • Simply stuff the couch cushions to the desired firmness.
  • Restoring the structural stability of foam-filled sofa cushions requires inserting the filler beneath the cover.
  • Alternatively, if the cushion foams become dented, you may always acquire new ones.
  • If you’re looking for a firm foam that will endure frequent use on couches, high resilience is your best bet.
  • Because the stuffing will be held securely in place by the tufting process, sagging couch cushions can be fixed and kept in place.

Option 2. Fix the sofa structure

  • Because softening might also be caused by the sofa’s structure, it’s not enough to simply replace the filling in the cushions.
  • If you have a sagging couch, you can restore its lost support by examining and possibly repairing the springs.
  • Once the sofa’s springs are replaced, the cushions will once again be able to firmly support your weight without giving in.
  • Put a piece of plywood about half an inch thick under the cushions if the springs aren’t the problem.
  • Weight distribution is improved by having an additional layer of material under the cushions, protecting them from punctures and keeping the seating area from flattening out.

What Do You Do If Your Couch Cushions Are Too Soft?

It is possible to stiffen sofa cushions by either reinforcing the fillers or replacing them entirely. High-density polyester foam is recommended since it does not degrade as quickly as other materials. Similarly, if you maintain your couch cushions regularly, they will last longer before they soften too much.

To prevent your sofa cushions from drooping, rotate them regularly. In this way, the cushions’ supporting composition will be preserved because wear will be evenly distributed across the material. Moisture and heat are detrimental to the fillings, therefore it’s better to keep the cushions out of such environments as much as possible.

Soft sofa vs firm sofa

Many people mistakenly believe that a softer couch is more comfortable, but this is not always the case. Too much sinkage in a sofa can promote slouching and bad posture. On the other hand, if you want to preserve your spine in its natural position, a firm sofa is the way to go.

How To Make Down Sofa Cushions Firmer

If you’re looking for the softest, most sumptuous option, look no farther than down. For the couch, however, a combination of down and foam is recommended to promote rigidity and prevent sinkage. Adding a foam core to your sofa cushions won’t diminish the down’s reassuring softness or comfort, but it will extend the life of your furniture.

You can also use a combination of down and feathers, weighed to your specifications, and then encased in polyester batting. To be sure, down is not the most user-friendly material for sofas when it comes to maintenance. To prevent your sofa cushions from becoming unusable due to filth and spills, it is recommended that you apply a sofa cover.

What Is The Best Foam For Couch Cushions?

High resiliency foam is ideal for couch cushions. High-density, compression-resistant materials are suitable for high-use furniture pieces like sofas since they hold their shape well over time. Memory foam, which can lose its form after being compressed for a while, isn’t as common as higher-quality latex and polyurethane foams for use in sofa cushions.

How Do I Stiffen My Couch Springs?

Checking the metal brackets of sagging couch springs is an easy fix that can restore the sofa’s original firmness. Each spring is attached at both ends by a bracket that can become loose over time. Fasten them back to the sofa’s frame with screws and make sure they’re snug.

Each sofa spring has a wire you can examine. They should be replaced because they can become detached from the springs. If you want to know more about repairing sofa springs, read this article.

Removable vs. Non-Removable Cushion Cleaning

Cushion coverings made from machine-washable textiles can be removed for cleaning. If you need to clean any other fabrics on your furniture, the manufacturer probably has some suggestions for cleaning supplies.

It’s recommended that you double-check the label on the upholstery before attempting a cleaning. A “W” indicates that a cleaner based on water is acceptable, a “S” indicates that a cleaner based on a solvent is acceptable, and a “WS” indicates that either type of cleaner is acceptable. If there is a red “X,” only have the upholstery cleaned by a professional.

How Often to Clean Couch Cushions, Other Upholstery

It’s not always necessary to wash the fabric of your couch cushions or other upholstery every time you clean them. Cleaning upholstered furniture should ideally be done once a month, and once a week at the very least involves vacuuming.

Every year or two, have your upholstery cleaned by a licensed cleaning technician if you prefer that method. Find a qualified technician in your area by contacting organizations like the International Institute of Inspection, Cleaning, and Restoration Certification. If you prefer to clean the upholstery yourself, you can refer to the instructions below.

What You’ll Need

Equipment / Tools

  • Rubber hand protection
  • Utilize a vacuum cleaner with a brush attachment for cleaning upholstery.
  • Cloth made from microfiber fibers
  • Bucket
  • A brush for use on upholstered furniture


  • Stain remover for upholstery
  • One-half of a teaspoon of mild dishwashing liquid without added colors
  • Calming, soothing, and soothing warm water

How to Clean Couch Cushions

Remove Pet Hair

Wearing rubber gloves, run them over the furniture to dislodge pet hair so it can be cleaned up more easily.

Vacuum the Upholstery

Move the vacuum from left to right in overlapping, short lines using the upholstery attachment. If you want to get in between the seams and under the cushions, you’ll need to switch to the crevice nozzle.

Treat Any Stains

For stubborn stains, you can use either a water-based or solvent-based cleaning, depending on the care instructions for your specific fabric. Allow the solution to soak in, and then blot the stain with a microfiber cloth. Avoid scrubbing the stain, as this may cause the stain to spread even further or may even damage the upholstery.

It all depends on the kind of stain you’re trying to remove. It may take more than one cleaning to remove tougher stains such as grease, blood, or ink than it would to remove a stain caused by a soda or juice spill.

Wash the Upholstery

To make suds, mix a half teaspoon of dye-free dish soap with a few tablespoons of warm water in a small bucket and froth it up. Use a soft bristled brush dipped in the cleaning solution to gently scrub the upholstery without soaking the fabric. When you’re done, use a moist towel to thoroughly clean the fabric. You should wait until the upholstered furniture is totally dry before using it again.

Washing Upholstery in a Machine

Upholstery covers that can be removed must meet two criteria before becoming machine washable: The fabric, first, needs to be preshrunk, and second, it needs to be a colorfast cloth.

  • In the absence of preshrunk upholstery, machine washing will cause the fabric to shrink, making it difficult, if not impossible, to reattach the covers to the cushions. If the cloth has been preshrunk, it should say so on the label.
  • It is possible to test the colorfastness of your furniture by rubbing a damp white cloth over a discreet area of the fabric. If the dye runs into the fabric, it is not colorfast and should be cleaned by a professional.

If your upholstery fabric can withstand being washed in a machine, you can follow these guidelines.

  • Cold water is gentler on clothes than hot or warm water.
  • On the first wash, use the gentle cycle to give your cloth the least amount of wear and tear possible. You may gauge its durability for future washes by seeing how it holds up in the washing machine.
  • Even if the slipcover washes well, drying it could cause it to shrink or fade. If you want to remove some of the moisture from the fabric without using heat, you can use the tumble or fluff setting.

How to Clean Urine Stains on Couch Cushions

Having pets increases the likelihood that you’ll notice a urine stain on your couch cushions or other upholstered furniture. To avoid the stain (and odor) becoming embedded in the fibers, prompt action is essential.

When feasible, take off the lid. Then, use a microfiber cloth to soak up as much of the liquid as possible. Don’t scrub or press too hard.

If the material can be washed in the washing machine, add a cup of vinegar to the rinse cycle. The next time you wash it, use detergent and the hottest water possible for the fabric type, then dry it on a clothesline.

If the fabric can’t be put in the washing machine, use an enzymatic cleaner made to remove urine stains (testing it on an inconspicuous area first). You also can make your own cleaner using 1 cup vinegar, 1 cup water, and 2 teaspoons dish soap. Dip a clean white cloth into the cleaner, and blot the stain. Then, use a different cloth or sponge to rinse with plain water, and let the spot air dry.

Tips for Keeping Upholstery Clean Longer

An enzymatic cleanser specifically formulated to remove pee stains should be used if the cloth can’t be washed in a washing machine (testing it on an inconspicuous area first). Mix together 1 cup of vinegar, 1 cup of water, and 2 tablespoons of dish soap for a homemade cleanser. To remove the stain, soak a clean, white cloth in the cleanser and blot vigorously. Let the area air dry after rinsing it with plain water using a clean towel or sponge.

If the item can’t go in the washing machine, try using an enzymatic cleaner designed for pee stains (testing it on an inconspicuous area first). A homemade cleanser can be made with 1 cup of vinegar, 1 cup of water, and 2 tablespoons of dish soap. To remove the stain, wet a clean white cloth with the cleanser and blot it. Next, rinse the area with plain water using a clean cloth or sponge, and allow it to dry naturally.

Avoid letting a stain dry completely if you accidentally make one. You should swiftly respond to any spills by blotting the area with a microfiber towel and then mopping. Dabbing the spill with club soda will give your cleaning efforts an extra boost. Small spills, such as coffee stains, can be wiped up using baby wipes in a pinch.

Sprinkle baking soda on the upholstery if a foul odor is present. Allow the powder to rest for 15–20 minutes, then vacuum it up.


How do you deep clean an upholstered couch?

Vacuuming the sofa or other piece of upholstery is the first step in a thorough cleaning routine. Remove any cushions that can be removed, and use the vacuum’s attachments to get into the nooks and crannies. Then, determine if the item can be machine washed, cleaned in a spot, or requires professional cleaning and follow the care instructions accordingly.

How do you wash cushions that cannot be washed?

It’s possible that you can spot-clean the fabric with an upholstery cleaner if you can’t wash the cushion covers in the washing machine. Alternatively, baking soda can be sprinkled on the fabric, left to sit, and then vacuumed up. This ought to help with scents in the seat cushion.

How do I dry my couch cushions?

The dryer is not the best place for cushion covers because the heat might cause them to shrink or distort so that they no longer fit the cushion properly. Fraying and wear occur in the dryer as well. If possible, hang the fabric to dry in a well-ventilated room. You can air it out by hanging it outside, but make sure to keep it out of the direct sunlight to prevent fading.


The level of firmness in a sofa is directly related to the level of support it provides. Cushions on sofas can be made firmer by substituting high-density foam or plywood for the original fillings. Restoring the couch’s pressure-resistance can also be accomplished by adjusting the springs that support the cushions.
