Purchased due to SI joint, sciatic nerve and lower back pain, I can finally sit comfortable in the Honda Pilot. The seat prevents my pelvis from rotating forward and therefore am in much less pain when I’m driving. Doesn’t work with a backless chair or one that has open lower back.

IT DOESNT APPEAR TO HOLD SHAPE LIKE THE ORIGINAL I BOUGHT 12 YEARS AGO

Just as a reference, I'm 5'9 190lbs.Before i got this cushion i was using a ComfiLife Gel sciatica cushion, which worked for a bit, but lost its support after 6 months or so. I had terrible back pain and pains shooting down my leg from sitting in a computer chair all day every day. I was at first reluctant to get the core lux. It was pricey, and had a few reviews saying it did absolutely nothing, but man am I glad i bought it.After buying the core lux and using it for about 4 days, hip and back discomfort is basically gone. The first day was rough. I was fidgeting all day trying to figure out how to use it properly. I thought it didn't work for a bit. Then i found a video on how I'm supposed to actually sit on it and position the cushion on top of a chair. Just wow. HUGE difference. The ComfiLife cushion doesn't even compare when it comes to pain relief.A warning though. This cushion, while very comfortable, is NOT for comfort. Its purpose is to force your hips and lower spine into the correct position, and while it does do an amazing job, you still have to keep your sitting posture in mind. While it does support the proper areas, if you don't activate the muscles needed for good pusture during use, it WILL NOT help you. It is a posture aid and will not magically give you good posture. However, it will make achieving good posture very easy.If you end up buying the cushion:When you sit on the cushion, make sure the back "handle" cutout area isn't touching the back of the seat. Make sure that the hole is under your tailbone, and that the pointy areas of your bottom are situated in the area right after the rubber texturing, but not directly on top of the rubber. The cushions front should reach about your mid thigh area. If the cushion is resting on the rubber peak on the plastic bottom, and your legs feel supported, you are sitting in it right. Just put yourself in proper posture and you're set.After you get used to the position its supposed to be in, if you want to easily plop down into the cushion, just put it in place and push the front area down so that the plastic area is flat against the bottom of the chair. Sit in it and you're good! No fidgeting needed.

Der Preis wirkt krass aber letztendlich hat es auch einen krassen Effekt. Diese Schmerzen im unteren Rücken sind komplett weg. Was soll man sagen... Sitzen ist generell nicht gut und man sollte wenn möglich einen Stehtisch besorgen und sich öfter bewegen. Aber wenn man schon sitzen muss, dann hilft das "Gerät" sehr gut.

Haven’t used it long enough but When you first use this you need to use it gradually or you will be sore. It will help you sit straighter
