Buying Guide: How to Select the Best Memory Foam Seat Cushion for Your Office Chair

Everlasting Comfort Seat Cushion for Office Chair - Tailbone Cushion - Coccyx Cushion - Sciatica Pillow for Sitting (Black)

Before purchasing a memory foam seat cushion, you  should keep in mind the breathability, durability, design and style, and ease of cleaning.


Breathability is one of the most important features you should look at. You don’t want a seat cushion that retains heat or moisture. Most modern office and task chairs are designed with this in mind.

So, if you’re layering a cushion over a chair, don’t compromise on this aspect. Make sure the fabric (i.e mesh) is designed to wick moisture and keep you well-ventilated during the day.


Our body weights differ from person to person. But the cushion should offer ample support for most body types. It needs to retain shape and ergonomics while adequately supporting the weight of each user over the long run.

One thing to look for when it comes to durability is a cushion made from 100% therapeutic memory foam.

Always check the specs and reviews to ensure the product will hold up.

Design and style

Obviously not from the comfort point of view, but design is genuinely important for seat cushions.

Since the prime reason to choose a memory foam cushion is comfort, proper design and style must ensure comfort.

Do you want something that blends in to your current chair, with consistent color and style? Or is the design less important than pure comfort?

In either case keep an eye out for additional design features, such as non-slip and textured surfaces, ergonomic shapes and raised contours to support the tailbone, hollow middle sections to reduce pressure on the perineum and improve breathability.

Ease of Cleaning

Hygiene is also an important thing to keep in mind, especially when talking about a seating product you’ll use on a daily basis. Make sure you pick a product that can easily be washed.

Most of the best memory foam cushions for office chairs and task chairs include removable covers that are washable; still, check before purchasing.


Q: How can I use memory foam seat cushions? 

A: Just place the memory foam seat cushion on the sitting area. That will act as your primary cushion or your seat. Now you can comfortably sit on it and relax.

Q: Which is the best memory foam seat cushion? 

A: In our view, the best memory seat foam cushion is the Xtreme Comforts Memory Seat Cushion that provides lots of comfort and relief from any back or spinal pain.

Q: How thick should a memory foam seat cushion be?

A: The approximate thickness of a memory foam seat cushion should be 3 inches. That provides enough additional cushioning for most users. However, if you are heavier, look for cushions with added thickness and dense foam.


As you can see, there are some good, low-cost options out there to quickly improve the comfort of your chair and provide therapeutic benefits during the workday.

Our top pick is the Xtreme Comforts Memory Seat Cushion, as it will work well for most people and handles the basics of comfort and relief without any major quality or sizing issues. But be sure to look closely at the specs and evaluate the designs based on your specific comfort needs.
