Spend long enough in a chair and you’ll end up slumped and in pain, with bad posture and a sore bottom. One way to relieve the pressure on your body is to carry a seat cushion. There are a couple of different kinds.

Portable memory foam cushions are designed for use wherever you plan to park your butt, from your office chair to the seat of your truck. Traditional mat-type seat pads are also a popular way to add comfort to your car seat. Pads come in different sizes, shapes, and materials. Here are three examples to help you figure out which is right for you.

Top Pick

Options with non-slip bottoms and orthopedic shapes help make sure your posture is good while driving and can reduce leg and back pain. Everlasting Comfort

If you’re a road warrior who spends lots of time in planes, trains, and automobiles, cushions are an easy way to spare yourself at least some of the wear and tear of being on the road.

Road Trip Pick

These are designed for automobiles to help keep your buns less sweaty on the road. They come in lots of sizes, so make sure you get the one that’s right for your vehicle. Big Ant

If you sit a lot, and sitting makes you hurt, take steps to solve the problem. One of these mats will help alleviate the hours on the road or sitting behind a desk.

Extra Inches

These pads help add height and comfort to your seat without pressing up against the bottom of your thighs on long drives. Everlasting Comfort

Sorry folks, but some of us just come in smaller sizes. If you have a hard time seeing over the steering wheel, a pad will give you that lift you’re looking for. (Don’t worry, big people, you can still use a seat pad for its other advantages if you lower your seat.)
