The Everlasting Comfort Memory Foam Seat Cushion is designed to provide comfort and support for long sitting periods, making it suitable for both office and car use. One of its standout features is the ergonomic 'U' shape cutout, which helps alleviate tailbone pain and encourages good posture, making it a great option for those suffering from back pain or sciatica.

Crafted from 100% high-density memory foam, this cushion is built for durability and offers a medium firmness that can support individuals weighing 130 lbs or more. Its dimensions (17" x 14" x 2.95") make it a standard fit for most chairs, whether in the office, home, or while traveling. Additionally, the non-slip base ensures that the cushion stays in place, enhancing comfort during use.

The soft and breathable cover is another plus, as it is machine-washable, making maintenance easy. This is particularly helpful for users who may need to clean the cushion regularly due to spills or wear. However, there are a few drawbacks to consider. While the cushion is effective for many, some users may find it less suitable if they require more specialized orthopedic support. Additionally, the recommendation for users over a specific weight might limit its appeal to a broader audience. Some users have also reported that it can feel too firm initially, which may cause discomfort until it softens with use. Lastly, it's worth noting the cushion's eligibility for Health Savings Accounts (HSA) and Flexible Spending Accounts (FSA), which may be beneficial for those looking to offset costs. This seat cushion is a solid choice for those seeking improved comfort and support during extended sitting, especially in automotive or office settings.

However, the cushion's large size, with dimensions of 18.11 inches by 14.17 inches, may not fit all chair types perfectly, which could be a minor drawback for some users. Additionally, while the medium firmness may suit most people, those who prefer very soft or very firm cushions might not find it ideal.

The cushion's ergonomic design promotes healthy posture, further enhancing comfort during extended use.

One of the key strengths is its non-slip rubber bottom, which ensures that the cushion stays securely in place, preventing any unwanted movement while driving or sitting.

There are a few aspects to consider. While the cushion is soft, some users may prefer a firmer feel, as the softness can sometimes lead to a feeling of sinking in rather than being fully supported. Additionally, while the cooling gel layer is beneficial for comfort, it may not retain its cooling properties for long periods, especially in warmer environments.
