Can you tell me the weight limit on the cushion?

I bought this cushion 16 months ago. As a 400lb person I can tell you that it provided sufficient relief for at least 12 months of all-day use before it became too flat to be helpful anymore. At this price I would call that a good investment for a year's worth of daily pain relief.

Does it really give a firm support?

The Everlasting Office Chair Cushion is made of 100% premium quality memory foam seat pillow, just like the world’s leading memory foam manufacturers. Using heat-responsive technology our advanced foam seat cushion for office chair molds perfectly to the shape of your bottom- guaranteeing custom support yet retains its shape after each use.

What are the dimensions of the cushion?

The Everlasting Comfort Seat Cushion is 17.5" x 13.5" x 3". Our memory foam seat cushion’s versatile design is an ideal fit for most common office chairs, car seats, stadium seats, wheelchairs, airplane seats, etc. Please check our product dimensions to ensure the size fits your needs.

Anyone had success with this helping chronic sciatica? so far, the backjoy seat has helped tremendously with sciatica. but wondering about this too.

This helped with sciatica and also the injury at the root of this with my piriformis muscles. I was in pain for a long time (two years). This was a key part of my healing process. I had other seat cushions (bamboo), which did not make a difference. This did.
