Premium Quality for Long Workdays and Travel
I love this lumbar back support pillow! Lifesaver for Back Pain – Excellent Support! This Xtreme Comforts lumbar pillow is absolutely amazing! The memory foam provides the perfect balance of firmness and comfort, cradling my lower back beautifully. Since using it, my posture has improved significantly, and my daily lower back pain is completely gone. It stays perfectly in place and doesn't flatten out over time like cheaper pillows. I love how easy it is to move this lumbar support pillow around. The adjustable strap holds it tightly to my office chair, my car seat, and even my kitchen chairs without slipping. The mesh cover is breathable, so it doesn't get hot during long hours of sitting. but Xtreme Comforts nailed the design on this one. It is an absolute must-have if you spend long hours sitting at a desk or driving in a car. The ergonomic shape perfectly targets the lumbar region, relieving pressure instantly. The cover is easy to unzip and wash, and the overall construction feels premium and durable. True value for money! It is a fantastic, high-quality cushion that goes everywhere with me! Highly recommend!

LOVE this back support! Perfect fit for me :)
I bought two cushion supports for my car seat (which have helped a lot). I'm driving a 2017 Prius and the drivers seat (combined with other factors I'm sure) caused my back to have incredibly severe, painful spasms. I've been doing many things to help Heal it (more details below) and one of them was to buy support cushions. The first cushion I bought (and I'm still using) is a wedge shaped cushion to sit on. My seat is slanted oddly so the front of the seat is higher than the back of the seat which irritates my back ... I wanted it to be more even so the wedge cushion made by Clever Yellow works well enough, and is available on Amazon. The second is this cushion to support my lumbar region. I like it because it has a convex (rather than concave) shape... most lumbar support cushions seem to be concave and that tends to bother my back. This cushion was one of the only convex cushions I could find and I love it!! When I first sat back on it I felt the relief up my spine/back and felt like I was entering a transcendent state. It really was that helpful to me. I also like it because it's taller than most, just the right amount of firmness for me, very thick, has a removable cover, and really supports the length of my back (taller cushion than most). I tried this cushion on a variety of different couches and chairs in addition to my car seat and it worked well on most of them. It was only a bit too thick on one, for me ... a traditional, rolling office chair. It felt like I was falling off the chair a bit because of it at first, although I adjusted it and it was ok. I don't tend to need a cushion on that chair anyway because it offers adequate lumbar support. It *is* a thick pillow. So that is something to consider when purchasing. It pushes me forward a bit in my car seat, which I actually like (I just put my seat back), but that may be an issue for some people. To me, because it is thick, it is also firm. I can sink back and still feel very supported. The cushion doesn't get flattened out like some. I also tried another lumbar cushion by NurtureSoft but it was more concave shaped than I thought it would be from the pictures and it was not as thick or as firm. It didn't work out for me but it got very good reviews so it may work better for you! It was roughly the same dimensions of this one I think, but rather than being taller (vertically), it's wider (horizontally). I wanted and needed more support up the length of my spine. Someone else might want/need more support on the sides. That could help determine which one you choose. Plus your height/torso length! So it may take a little trial and error to find the right one. Luckily, the Xtreme Comforts cushion was my first choice and ended up being my favorite! :) Some other things that have helped my back, that might help you too ... * The book Freedom from Pain by Peter Levine. I can't write much about this one yet, as I just received it today, but I'm looking forward to reading it. I've been doing Trauma/Tension Release Exercises (TRE) multiple times a day and they have really really helped me (along with gradually increasing the distance of my walks), so I'm optimistic about learning about other exercises in the book! * Also planning on buying insoles and new shoes, as well as do Network Spinal Analysis at the chiropractor (a very gentle approach ... traditional chiropractor tends to trigger my body and make the bracing worse). I'm hoping the chiropractor might be able to suggest insoles/shoes and posture-correction apparel as well. A month ago I was unable to move because of my back pain. It's gotten much better and I have Faith it will continue to do so! Grateful for these supportive products to help me function better along the way!! If you're reading this and in pain you're in my heart and prayers. Hope you feel better soon!!! :)

A Game-Changer for Long Hours at the Desk – Supportive, Comfortable, and Travel-Friendly
After trying several seat cushions that flattened out or shifted around, the Xtreme Comforts Memory Foam Coccyx Seat Cushion finally delivered on what it promised. I work from home full-time and sit for long stretches, and this cushion has noticeably improved my posture and reduced the pressure on my lower back and tailbone. The U-shaped ergonomic design really does relieve that “numbness” that creeps in after hours of sitting. The memory foam holds its shape well—it feels firm but comfortable, offering real support without collapsing like cheap alternatives. I also appreciate the non-slip bottom, which keeps it in place even on slick office chairs. Bonus points for the carrying handle and storage bag—I’ve taken this cushion on a few long drives and it works just as well in the car or on bleachers. It’s a versatile option if you travel often or want something you can move between office, car, and home. If you're someone dealing with sciatica, tailbone pain, or just general discomfort from sitting too long, this cushion is absolutely worth the investment

Good Quality but pushes me too far forward in my vehicle
This cushion works okay but it pushes me too forward in my vehicle, as do most cushions like this and I was hoping it wouldn't. I don't use it the entire time I'm driving on a long trip and was only intended to be used to change the position of my back after about 90 minutes of driving assuming I'm driving at least another 30-60 minutes longer. Although I would not buy this again I do think it's one of the better seat cushions on the market. How I review: When I review a product said product automatically starts with four stars as I rarely will purchase anything below four stars. I then add and/subtract stars based on certain criteria as listed below. 1. If an item is exactly what I expected and nothing more it will receive a four star rating 2. If an item surpasses my expectations it will gain a star 3. If an item goes slightly below my expectations it will lose a star 4. If the instructions for the product (if needed) are poorly written (hard to understand due to language issues or grammar) or just too hard to follow it will lose a star no matter if the product meets or exceed my expectations 5. If a product is significantly below my expectations I will deduct two stars 6. It will be rare that I would give a product one star since I buy mostly items that have a 4+ rating but in rare instances there may be a good reason that even a four star product gets a one star rating from me. It could be because of customer service issues from the company but whatever the case is I will clearly explain my reason for giving a product only one star

Comfort + Support!!!
Paired with the chair cushion, this lumbar back support pillow is providing both comfort and support as I work from my desk 8 hours a day! Lower back pain has definitely lessened since I've started using this combo!

Great cushion!!!
I love this cushion! When I was young, I broke my tailbone and have always had trouble with it. This cushion takes away all the trouble. I bought one for our vehicle and then I bought one for my seat at the kitchen table. I might even buy one for our second vehicle because it's wonderful to have the comfort of this cushion!

Helped my pregnancy back pain
I work at a computer and this helped my back pain when I was pregnant. The only downside was that it was thicker than I expected which left me a smaller seat capacity. But it was soft and the straps were flexible enough to be positioned on the chair as needed.

Supporting & comfortable
the supplied lumbar cushion I got with my chair was trash. took a punt and got one of these, the soft memory foam had me straight away and I ended up getting 3 of them (Car, Home and Office). Only knit pick is the strap should allow it to be tighter around your more narrow chair backs, apart from that its great.
