    Additional Details

    BackJoy SitSmart is an innovative sitting device that naturally relieves back pain by optimizing your sitting posture.

    If you sit for long periods of time, posture support is key. SitSmart is a simple posture corrector that restores the natural curvature of the spine to relieve lower back pain. Without SitSmart, your muscles flatten and tense under your body weight, causing pain.

    What is the difference between the various SitSmart styles?

    The new SitSmart Posture Core has several new features that make it easier to use and differentiates it from our other SitSmart seats.

    • 2x comfort cushioning - Padded EVA foam covering for all-day comfort
    • Wider seating surface & deeper bowl shape - Fits a variety of body types
    • Sculpted front pummel - Helps you sit on the product correctly
    • Built-in finger grip - Helps you adjust the seat easily beneath you
    • Visual indicators - Makes it intuitive for you to sit on the seat correctly

    Will SitSmart Posture Core fit my bottom?

    All SitSmart seats are designed to fit adults between 100 to 300 lbs.

    Your SitSmart will still be effective even if your buttocks are slightly larger than the product. 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 provides.

    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.

    Will SitSmart work for my condition?

    SitSmart can work hand-in-hand with your therapeutic regimen. SitSmart will not cure your back pain, but it will relieve the pressures and strains caused by sitting that aggravate your underlying condition so you can be comfortable.

    Here are some of the conditions that SitSmart may help relieve:

    • Low back pain
    • Herniated discs
    • Degenerated discs
    • Compressed discs
    • Back injuries
    • Hip injuries
    • Neck/cervical pain
    • Sciatica
    • Coccyxdinia (sore tailbone)
    • Scoliosis
    • Spinal stenosis
    • Osteoporosis

    How do I clean my SitSmart?

    Wash with mild soap and water or standard upholstery cleaner. Do not put in laundry machines or dishwashers.
