The TushGuard Office/Car Seat Cushion is designed for those who spend long hours sitting and need a comfortable, supportive seat cushion. Made of 100% pure memory foam, it is both soft and firm, using body heat to conform to your shape.

The cushion’s size (18.11 x 14.17 x 3.15 inches) makes it suitable for a variety of chairs, including office chairs, car seats, airplane seats, and wheelchairs.

The non-slip rubber bottom ensures the cushion stays in place, adding to its practical design. Additionally, the cushion comes with a machine-washable, breathable cover, making it easy to keep clean. A built-in handle adds to its portability, allowing users to easily carry it from one place to another.

While the memory foam provides good support, some users might find it too firm or too soft depending on their personal preference. The large size might not fit all types of chairs perfectly, and some might find it a bit bulky for use in compact spaces. Despite these minor drawbacks, the TushGuard cushion is particularly beneficial for adults who need extra support while sitting for extended periods and is safe and certified free of harmful additives. For a reasonably priced cushion that provides comfort and support, the TushGuard is a solid choice.
