Review: Long duration calls and living in front of a computer. This works! - I use this for 10-15-hour-long days as I work from home and am the proverbial workaholic. I found this to relieve a lot of pressure from the lower back and the legs also feel more rested. Less unease that i was feeling once I move to this. This is also non-slip and even after prolonged use it has not lost shape or form. This is now the default for me. I am constantly on video calls and adjusted the camera to account for my new sitting position rather than remove it during a call as this is worth it from how it makes me feel and recover from a long day. No sweat. No awkward feeling when perched on it.
Review: Magic Booty Cushion - I am absolutely blown away by the **CJACSOC Extra Large Memory Foam Seat Cushion**! This cushion is an absolute game-changer for anyone who deals with discomfort from sitting for long periods—whether it's at work, in the car, or during travel. First of all, the size is PERFECT. It’s extra large, which gives fantastic coverage and support for your entire seat area. No more worrying about feeling cramped or unsupported. The memory foam is incredibly high quality; it molds to your body beautifully, offering just the right amount of firmness while still being plush and soft. It helps distribute my weight evenly and provides constant comfort throughout the day. The cushion also provides excellent lumbar support, which has drastically reduced the lower back pain I used to get after long hours of sitting. It feels like a custom fit every time I sit down. Whether I’m working from home or sitting for a long car ride, I can’t imagine going without it now. Another standout feature is the **non-slip cover**, which keeps the cushion securely in place no matter how much you move. I also love the breathable, soft fabric, which is gentle on the skin but still durable and easy to clean. Honestly, the **CJACSOC Extra Large Memory Foam Seat Cushion** has taken my comfort to the next level. If you’re looking for a seat cushion that will last, deliver real results, and make sitting a whole lot more enjoyable, this is *the one*! It’s worth every penny, and I couldn’t recommend it more!

### ⭐⭐⭐⭐ Relieves hip pain on long drives.
*by E***S on December 11, 2025*

I bought this to raise the driver’s seat, but it’s so wide, I had to fight to get the seatbelt buckled. It was very comfortable driving across the US though. I should have measured the width of my driver’s seat before ordering. The higher edges make it harder to enter the car and I don’t really see why the high sides are needed to cradle your tush, but once you’re in and can lift yourself high enough to slide the cushion back toward the center so you can buckle your safety belt it works great. It slides away from you getting into the car much easier than it slides back once you’re in.
