What to Look for in a Seat Cushion

If you plan on using office chair cushions for long periods, consider what they’re made from, their shape, and their thickness to ensure they will support you well.


Your seat cushion’s materials can affect its durability, supportiveness, and responsiveness. Most seat cushions are made from poly-foam, memory foam, or latex foam, and have a soft and breathable cover. Some seat cushions are even made entirely of gel. Let’s take a look.

  • Memory foam: A memory foam seat cushion can be responsive and pressure-relieving. Since memory foam can get hot, most newer memory foam cushions are infused with materials such as gel, copper, or graphite to make them cooler.
  • Latex: Latex is bouncy and supportive. It contours less closely than memory foam but still relieves pressure and pain. Latex can be a bit expensive, but it’s durable, so it may last longer than some other options.
  • Poly-foam: Poly-foam is a synthetic and inexpensive variation of memory foam or latex foam. While it’s pressure-relieving at first, it can wear down and grow lumps quickly, making it less supportive.
  • Gel: Gel seat cushions are known for being cooling and reasonably priced but aren’t always the most supportive or durable. If you’re looking for something to cool you down and minimize pain, consider a gel-infused cushion with foam.


Seat cushions are all built to be roughly the same dimensions as chairs, but they come in several different shapes to promote different benefits, such as square, tapered, or U-shaped.

A flat square-shaped seat cushion can be effective, but you might also consider a tapered or U-shaped seat cushion to reduce back pain or have a tendency to slouch. Tapered and U-shaped seat cushions are designed to improve your posture and won’t exacerbate lower back pain.


Comfortable seat cushions can be between 1 to 3 inches thick, but your body weight will influence the exact thickness you need.

Thin people generally won’t need a thick seat cushion since they won’t place as much pressure on the cushion. Conversely, large people will likely need a thicker seat cushion to ensure they reap all the benefits of it.

With thickness in mind, a lumbar cushion’s thickness can affect the ergonomics of your office space. Too high or low of a set-up can cause stiffness and discomfort.

When seated on your seat cushion, ensure your feet are flat on the floor and your wrists and forearms are in line with your desk. Most desk chairs are adjustable, so you should be able to adjust your chair as needed to accommodate your seat cushion.


How do you keep a seat cushion in place?

Having your seat cushions constantly sliding out of place can be annoying to deal with, especially during work or school. Some seat cushions have a non-slip rubber bottom, but if yours doesn’t, you can use a non-slip pad or tape between your seat cushion and the chair. You can also use an adjustable strap to attach your seat cushion to your chair.

How long do seat cushions last?

Seat cushions made from high-quality materials—such as memory foam or latex—can last up to seven years with proper care. Eventually, they will flatten out and won’t support you enough, so you’ll need to replace them.

Are seat cushions allowed on airplanes?

Yes, just like many people bring pillows on planes, you can do the same with a seat cushion. With this in mind, you should always double-check your airline’s guidelines before traveling.

Seat cushions are often small, lightweight, and fit as carry-ons. They’re great to use when traveling by plane, train, or car, especially if you’ll be traveling for a long period of time.

How long is too long when sitting?

Experts agree that sitting down for long periods of time is harmful to your health. While using a seat cushion can reduce the pressure on your body while seated, you should still sit for no longer than 30 minutes per hour.

Instead, you should stand at your work station for 15 to 30 minutes every hour while working or at school. Some desks have a sit-to-stand design built so you can easily switch between sitting and standing.

It’s also a good idea to walk around your office or home for several minutes every hour. Also, whenever you’re on the phone or watching television, try standing up rather than sitting.

What happens to your body when you sit too much?

Sitting for even more than 1 hour affects your lipoprotein lipase activity, one of the enzymes involved in fat metabolism. Also, the glucose in your system metabolizes into fat rather than muscle, leading to weight gain.

However, even if you do exercise regularly outside of sitting at work or school, sitting will still negatively impact your body. For this reason, make it a priority to stand up regularly.


Although a seat cushion won’t cure your lower back pain or stiffness when sitting for long hours, it can alleviate some discomfort and make sitting easier. While you should still make an effort to stand up while working, office seat cushions can help prevent the muscles on your bottom, thighs, and hips from tightening and aching.
