My spine has filed an official “thank you” note.
Color: Grey
My spine has filed an official “thank you” note. The Cushion Lab Lumbar Pillow is the kind of back support you don’t realize you desperately need until you try it—and then suddenly you’re wondering how you ever sat without it. Why It’s Amazing: • Ergonomic magic – the curve hits exactly where your lower back needs it, like a hug for your lumbar. • Memory foam comfort – firm enough to support, soft enough to feel luxurious. • Versatile – works perfectly for office chairs, car seats, and even my too-cute-but-utterly-unforgiving accent chair. The Experience: From the moment I leaned back, it was like my spine exhaled. I’ve gone from fidgety and slouchy to upright and comfortable—even through long work sessions. Verdict: ⭐️⭐️⭐️⭐️⭐️ Back bliss achieved. If your chair isn’t cutting it, this pillow is basically an instant upgrade for your posture and your mood. ... show more

Great Support
Color: Black
This product is fantastic. It really helps with any upper and lower back issues. It is very comfortable for a work-from-home position. I recommend the cushion as well as the lumbar support.

Helps with back pain - wish the strap tightened more.
Color: Grey
I ordered the seat cushion and this back support to use together for a very uncomfortable office chair. What I like: It's supportive to my back. Helps me retain my posture when working. Has a strap to hold it to the chair (see below). It pretty much fits the small chair I am using Works well with the seat cushion. The quality is good. Helps with back pain. What I don't like: It is not pleasing to look at - since I have to look at it every day, I wish I could cover it up with something else - bleh. The strap only tightens so far so if you have a small chair it won't stay put so I'm constantly adjusting it - it won't ever be tight enough to keep it where I want it. If I'm sitting against it, it'll pretty much stay but it's not completely ideal. The seat cushion was packed in a box but this came just in some plastic and that made me worry Amazon did it's thing of sending returned items as new - it looked new and didn't have any odor to it, but still that trust with Amazon isn't there any longer. I wish they had a 'set' price for the seat cushion and back cushion but they didn't for these two items I ordered. Super fast shipping (I do have Prime). Overall, I am happy with my order. The seat and this back cushion saved me from having to buy a new office chair. ... show more

Just get it
Color: Wellness Green
Oh no....now I have to keep it because it is so comfortable. I was really hoping this would be as overpriced as I imagined so I could get something else, but it really is the best one I have tried. I have chronic low back and neck pain. I got this for the car but I can't stop using it on my recliner for long enough to try it in the car. I work with my hands and like to watch tv at the same time, but if I am not at my desk with my ergonomic chair then anywhere else I usually get debilitating back pain. I've been able to craft from the couch (yay?) in the evenings so I'd say this is a great investment in being able to walk without pain and get more done. Take the chance! I thought I wanted something that was around 8-9 inches so it wasn't too high, but this is the perfect size. It doesnt leave my upper body floating to support itself. I am 5'6. The memory foam is so sturdy and the fabric is soft. ... show more

Give it a couple days and your lower back will thank you!
Color: Black
When you first use this lower lumbar support pillow you will probably hate it like I did. Sitting may feel unnatural and you might find it hard to get comfortable, but that's kind of the point of this thing: it FORCES you to sit correctly. Once you give it a day or two to get accustomed to it you will find that the "comfortable" way you used to sit is what was causing your back pain all along. My lower back and tailbone haven't hurt in weeks since using this. I love it! ... show more

Built as advertised, but too thick for my seating
Color: Grey
This pillow is high quality and very well made. I particularly like the firmness, which makes my back feel great. But after a few days, I began to realize this pillow is causing another problem. Because it is so thick, it pushes me forward in my chair and thus out of alignment with the center of the sculpted "seat pan" in my chair. I am told by the ergonomics people at my company that there should be about 3 fingers width of distance between the back of your knees and the front edge of the chair. But adding this cushion to my chair increases that distance significantly. After a few hours, my back feels fine but my butt is aching from being "out of position" for my chair. And I have a similar experience in my car (which also has a highly sculpted seat pan). If you have oversized chairs, or simple chairs that don't already have a lot of ergonomics already built in, or ones that allow you to extend the seat front further than usual, this pillow will probably work just fine. But for me, it's been a miss. To be fair, I now realize it's unlikely that any lumbar cushion would work with the sculpted design of any highly ergonomic chair that is designed to keep you positioned in one ideal position. It certainly doesn't work with my Herman Miller. I now realize that my best solution is to rely on the ergonomics that are built into my chair and not add any extras like this at all. ... show more

Excellent quality item!!!
Color: Black
I absolutely love this! I put this on my desk chair at school and it is so good for my back. I love the way the strap has little grip on it and it kind of helps keep it in place! This is an excellent well made high quality item! I highly recommend it!
