Product Description

 Back Support Cushion for Lower Back Pain | Sciatica Pain Relief | for Adults (100-300 lbs)

SitSmart is an innovative sitting device that naturally relieves back pain by optimizing your sitting posture.
The Posture Plus style features comfortable, durable foam on the top that's completely weatherproof for indoor or outdoor use. Safe and effective to use, it automatically positions your body in correct posture for all-day comfort. Its patented design works by tilting your hips upright and comfortably "floating" your spine over the seat.
• Natural back pain relief
• Easy-to-use design for correct posture
• Tilts the pelvis upright to engage core muscles
• Maximum comfort for long periods of sitting
• Works in any seat-office, car, home, or outdoors

Detailed Images

How is the Posture Plus different from other SitSmart models?
The only difference between the various SitSmart models is the surface material that covers the seat. The SitSmart Posture Plus style is covered with a waterproof EVA foam that's soft, comfortable and durable. It comes in a variety of fun color options.
Regardless of which style you choose, your SitSmart will position your body in correct posture for all-day comfort.
What size do I need?
SitSmart is designed for adults 100 to 300 lbs. SitSmart Mini is made for children and teens 70 to 120 lbs.
If you are an adult deciding between SitSmart and SitSmart Mini, we highly recommend choosing the standard SitSmart size. Adults with extremely petite frames and shorter statures may choose the SitSmart Mini.

My SitSmart is too small. Is there a larger size?
our SitSmart seat must be smaller than your buttocks in order to work properly, meaning your SitSmart will still be effective even if your buttocks are slightly larger than the product.

SitSmart standard size is designed for adults 100 to 300 lbs. Because SitSmart is designed to cup the pelvis itself, not the soft tissue around it, the standard SitSmart size fits nearly all adults regardless of weight or height.

First, make sure that you are sitting on top of your SitSmart and not using it propped up behind you. Changing your sitting posture can cause temporary discomfort – like going to the gym for the first time. Your body may need time to adjust and relax into the new posture that your SitSmart provide

Does SitSmart work on soft couches?
Yes! SitSmart works just as effectively on soft couches and car seats. It is important to note that when you sit down into the soft cushions of a couch, your gluteus muscles can stretch and flatten even more than they do when you sit on a hard chair. Such stretching and flattening can aggravate back pain, so it's definitely beneficial to use your SitSmart while relaxing on the couch

When should I feel results?
Many users experience immediate relief, and some require several weeks of regular use to feel the benefits of their SitSmart. If you don't feel any change when you sit on your SitSmart, make sure you have closely followed the sitting instructions and your buttocks muscles are firmly cupped.
