## Description

The combination of two choice best selling Integral Skin cushions is a great gift idea for the holidays. SITTS created the bundles to help the buyer to share with their friends and family. As we age, often we are developing the abnormal curves in the lower back, thorax and neck on a daily bases. SITTS helps your body to develop a proper posture reflex within spine by gently lifting gravity pressures over the center and into a perfect balance. Hopefully with time can reverse the aging of the bones' structures, increasing circulation then eliminating inflammation. Our standard sitting posture may give us a sense of a normal balance, but in reality we are slouching, and sitting on the spine poorly, this can begin a repetitive strain in neck, shoulders, or low-back. We all know the failure of chairs and car seats to help our natural sitting position, but changing needs paying attention to developing a new posture, a constant 24/7 ordeal . This is in itself stressful if applied everyday. SITTS helps that you achieve that easily with a firm but flexible balance and support, just the right amount of support to keep your back safe and promote alignment health.  Integral Skin is the key ingredient in the flexible softness and smooth as butter feel that is hallmark of this unusual sitting experience. Heat activated covering was to create a buoyancy that delivers a perfect long sitting ergonomics. "I feel instant relief" or " My spine feels like its expanding" or as a elderly lady siting on a 2.5'' cushion stated, " I feel tingling in my back", and then there are children that love the cushion at the festivals. Usually just sitting quietly for awhile enjoying what its like, usually requesting to take one home. Washable flexible surface for all occasions. Therapeutic for all ages to use, even grandmother loves the cushions, but most likely can sit well with the smaller versions.

## Features

- SITTING POSTURE is the new smoking in the office, getting the best possible ergonomic sitting position curbs repetitive strain injuries where your less and less causing re-injury to the same low back, shoulder, or neck muscles day after day.
- CUSTOMER SATISFACTION is so important that we request thinking about whether you like the cushion FIRM, Medium, or soft and please contact seller with your choice, and if you fold a towel twice, and make into a triangle, check which size may be best in different seats. This gives you a idea, what size may be best for you. Usually 150lbs+ uses 3.5 and 4 inch. Under 150lbs choose 2.5- to 3.5 inch. Elderly and chronic severe pain- the 2.5"
- ELIMINATING PAIN requires effort daily, but can be sustain by implementing a upright posture. SITTS strength is in whether you can rebuild core deep flexibility within the spine. You'll love how easy it is to sit upright and may become addictive, because it feels good. Easy proper sitting performance plus better balance, is a key to core awareness. This develops dynamic stability. 3.5 inch has been a great therapeutic tool in recover after surgery to avoid irritation to surgery sites.
- LOOKING FOR SLOUCH CONTROL: The easy effects of the 3.5" wedge orthopedic seat cushion for sciatica back support and coccyx pain will lift weight off the back of pelvis and relieve pressures off involved vertebrae. The cushion fills in ditches, leveling or fitting snugly into seats, helps the user to redistribute weight evenly in spine from painful C shape to a J-S shape that is required for pain relief. The shape creates circulation to lower back strains.
- BUTTERY TEXTURE is washable Integral Skin and can take a minute to wash. Ideal for car seats as it won't slide around, great in Kayaks because will help your back last for hours of rowing. Travels on planes exceptionally well, portability is a easy because its lightweight and cannot harm it, durable surface. Take to the games and sit for hours at the beach. I know having more than one is so helpful, different seats available make it easy to exchange them and see different styles of sitting.
