Description
Many of us spend a large portion of our day sitting, whether at a desk at work, driving in the car, or watching T.V., and maintaining a good posture is often the last thing on our minds. Unfortunately, this lack of correct posture causes stress to the lower back and can lead to a lot of pain and discomfort-but hope is not lost! By using good-quality, ergonomic back cushions, you can be sure your shoulders, neck, and pelvis are properly aligned and your spine is in a neutral position, thus avoiding unnecessary stress on the coccyx. That's where we come in! We provide only the very best support cushions, ones that are comfortable, sturdy, and designed to quite literally take the pressure off. Our ultra-comfortable ORTHOPEDIC MEMORY FOAM SEAT CUSHION is ergonomically contoured to distribute body weight evenly. It also offers supportive padding that gently conforms to the contours of your body, working as a perfect aid to keep your coccyx, spine, and hips buoyant and relaxed. The durable combo works to support your back for maximum comfort during long periods of sitting. These two products work in harmony to alleviate sore, swollen muscles and joints, and to prevent back pain, while at the same time giving you the feeling that you're sitting in the most comfortable, luxurious seat you've ever encountered!

Description
Milliard Lumbar Cushion is made of memory foam to gently contour with pressure points and support your body as if it was molded just for you.Recommended by Chiropractors and Physical Therapists
Back pain? Fatigued from sitting for prolonged periods of time? Slouching? This cushion is designed to support one of the most commonly neglected areas of your body, and also one of the most frequently abused: your back - specifically your lumbar vertebrae. The lumbar region of your back is the section of your spine that supports you as you sit in an upright position. Bad posture and long periods of sitting at a desk can strain this section of vertebrae and the muscles that work to keep them aligned, so a lumbar cushion is an excellent way to encourage proper posture and help relieve pressure from your lower back muscles. Just slip the memory foam cushion between the back of your chair and your back to feel the difference a supported spine can make.
Great Travel Pillow
Use it in the office, in your car, at home in your favorite chair... just about anywhere you can fit a cushion in your life. Best of all, since it's memory foam, you can squish it to fit into bags or luggage, and then just pull it out and watch it expand back into shape again. Just don't forget it at home. It wouldn't forget you.
The Memory Foam Lumbar Cushion has been produced by Milliard with your health and comfort in mind. Don't forget to check out our other great products!
