Lumbar Support Pillow with Airbag - Ergonomic Lumbar Pillow with 5 Height Adjustable Chair Back Support & Breathable Mesh Cover, Back Support for Office Chair Car-Improve Sitting Posture & Pain Relief

I have been looking for a comfortable back support pillow/cushion since the pandemic. Most require a strap to be affixed to a chair. I work from home and needed a posture corrector for my office desk, couch, and bed (yes, I love working in bed). This works for any situation without the optional strap included. The angel wings are super comfortable, flexible to support your back and the part that leans against the chair or surface is hard so that it keeps your back upright. No foam (just wonderful mesh) so no yucky chemicals. This is one of the best purchases I’ve made this year!

The main reason it functions as designed is simply that it fills in the void created by the chair back and my back; I'm not so sure plugging the gap with a good, fat pillow wouldn't accomplish the same thing. This is mostly an over-embellished, "as seen on TV" kind of thing, mostly just junk.I'd still need to have a tray top across the chair arms or the like, reaching out on the desktop to the keyboard - which is the main body position while using the computer - all of which has the body forward enough that the back support (no matter what kind) is basically useless. Part of the equation is the type of chair, but pretty much all office and gaming chairs are similar enough that it is nearly universal. Leaning back on it gets one to a small bit of support, so it helps some when taking a break and a stretch.EDIT/UPDATE: In all fairness I should have thought to include a tidbit or 2 that may be relevant. I have severe, serious spinal problems, smashed vertebrae, blown out discs, and scoliosis, so I may not be the best candidate for giving this device a more "unbiased" evaluation. NOTHING helps my back, so the fact this didn't either, is no real reflection of its performance. Material wise, the components it is made from, yeah - my label of junk on that regard is completely unchanged.EDIT/UPDATE #2: As I had strongly suspected, the main issues were much more in this chair than the device. I woke up this morning with a possible solution in Mind and it worked out swimmingly (see photo). Stuffing this cushion in behind the unit got it pushed forward enough where it can do its job as designed and intended. This fix is FAR from optimum as things are still a bit askew as it all isn't in the kind of alignment - it is a cobbled together, short term solution. Once my office chair gets here, I'll be able to put this device to right kind of testing and functioning as it is supposed to do. The unit doesn't work well at all on gaming chairs and such where there are 'sides' protruding forward of the back of the seat - they're meant to wrap around a body in the same manner as the device. Now that it is sitting forward enough, I am getting the cradling function from it that it is designed to do. It can still use some padding and I'm not overly convinced that the type of plastic it's made from is the best of options (but I'm no expert on plastics so,..). I still think that it could fracture easily if it took a heavy hit - say a bigger, heavier person just 'throwing' themselves against it - a lot of people just 'fall' into/onto a piece of furniture rather than actually sitting down at a controlled manner; I'm as guilty of that as any other, especially when exhausted and/or in extreme pain. I am curious if constructing it from a type of carbon fiber on a 3-D printer may be a better option than plastic injection molding. I live in a hypoallergenic 'bubble' of sorts, synthetic fibers of any type irritate and/or leave me with a rash so I'll have to keep an old t-shirt or something over it. But, dreaming up a solution has proven successful after all.

My computer chair came with a removable lumbar cushion. I've had the chair for years, and I've probably used that cushion for a total of 15 minutes because it's terrible -- it's essentially a 12"x12" square with a convex face, a shape which actually makes the chair more uncomfortable. It was therefore logical to me that a concave lumbar support (like this one from FITBOX) would be better. I was right.The Benefits- From a comfort perspective, the FITBOX lumbar support pillow is outstanding. I prefer concave support (picture two giant hands cradling your low-to-mid back), but it's worth noting that. thanks to the inflatable component, the pillow can also achieve a flat or covex shape, if that's your preference.- Aside from easing back pain and promoting good posture, I was surprised to find that the pillow also eases tension on my neck. What's interesting about this is that even when I consciously "sit up straight" in my chair, there is some discomfort on my neck during long sessions at the computer, but adding this pillow eliminates it. I was hoping for no back pain, but I'll take the bonus no-neck-pain as well.The Drawbacks- The pillow's adjustable-length attachment strap isn't that great. At least on my chair, it will work itself loose periodically and I'll have to cinch it tight again. This is mildly inconvenient.- The two "wings" of the pillow are each attached to the back plate by two springs, so they don't look completely symmetrical. This is simply an aesthetic concern, but some people may care.- If your chair reclines, you'll have to remove the pillow to do so. I think the large size of the pillow plays a big part in its comfort, but it also makes it impossible to use my chair in its reclined position. Removing the cushion periodically is not an issue for me in my home office, but you may find it impractical in work setting.Ultimately, the only thing truly "wrong" with the FITBOX pillow is its attachment strap, but I'm willing to put up with it because it's the most comfortable lumbar (and apparently, neck) support I've ever used -- that alone makes it worth five stars in my book.

As shown in the attached photos, the two halves each rest on two springs (wrapped by rubber), providing flexibility reminiscent of expensive task chairs. The halves also curve and hug my back just right. With them installed on existing chairs, I no longer have to sit far back at all in order to reach support. For reference, I'm 5'6".Over the past 2 months, I've sat with this backrest for over 8 hours/day, and it's yet to show any signs of wear. The springs are still the springy comfort that they are. The fabric material seems like-new despite consistent use. Very happy with the product.
