Perfect lumbar support
Size: Back
I purchased this for our new Honda Civic seats that lacked lumbar support. I already have the Purple seat cushion for my work chair and it is outstanding, so I wasn’t surprised when this provided just the right amount of support we needed.

Very Comfortable, Great Support vs. Silly Setup, Bad Strap
Size: Back
Most lumbar support pillows I’ve bought feel like leaning on bumpy rock. This actually cushions and I feel better when I stand up whether it’s hours or minutes. However, the strap that’s supposed to hold it in place needs adjustment every time I sit down. Now I just lift it into place when I sit down. Setup was a bit frustrating. The picture shows the cushion coming out from the side of the case. However, the zipper runs across the case in the middle. This means you have to bend and twist the cushion to get it in place. If Purple is reading this, move the zipper to the top or along the side as pictured it would change install and removal time from minutes to mere seconds. I still wouldn’t return it to go find another back cushion that’s as good as this AND has a more secure strap system. The quality is that great. This is so comfortable Im now looking into possibly buying their bed.

Great for the Rowing Machine
Size: Back
Bought this to put on my rowing seat. Figured out I needed a cushion after I developed constant numbness on my thigh. The cushion puts the support where I need it, and the cover that comes with it keeps it planted on the seat. Zero slipping. I was worried the cover might fray and tear, but it hasn't after 3 hours a week for 5 months. This thing is expensive, but being comfortable is priceless.

The Purple Back Cushion
Size: Back
If you order this product you better use AI to figure out how to put this crap together. No instructions in box what so ever. For a company of this size not having instructions included is ridiculous. This is why I am only giving 3 stars before I use it. I actually think there are cheaper product out there without the confusion. I am using this product on my sofa. I have been using it for several days now and all I can say is don't bother throwing away your money. You can roll up s bath towel and place it in small of back against couch and get a better result.

Perfect back cushion
Size: Back
I love this cushion! I use it at sporting events and on airplanes. I also used it for my office chair after I had back surgery. Makes a big difference for me as far as comfort goes. The only con is that since it’s heavier, the strap can’t keep it in place very well, but it’s not a big deal to adjust it occasionally.

Over priced mediocre product.
Size: Back
Okay, well I bought this back cushion AND the super duper expensive seat cushion. I tried to review them separately but apparently they are just different versions of the same thing so Amazon is forcing me to combine their reviews. I REALLY wanted to like these. I like to spend time on my days off sitting at my pc and playing various games. All gaming chairs seem to think they need a seat pan that is hard as a sheet of plywood "to promote good posture". What if I don't care about my posture, darn it. Just give me a comfortable chair. Anyway, I digress. I have bought many seat cushions and have yet to find one that is big enough, soft enough, does not slide off or cause ME to slide out of the chair. Now none of them have been as expensive as these but I figured enough was enough. Time to pay for premium. Unfortunately what I got was just overpriced mediocre cushions. I have gotten same result from cushions that cost 1/4 this price. The back/lumbar pillow is just too heavy to sit properly. The single strap does not provide an adequate way to secure it to the chair. I feel like part of the blame is the style of chair I have so for the back pillow I would actually give it 2 maybe three stars. But regardless, it is NOT worth $80. Not even half that. I am sorry Purple, but this is true. Now for the seat cushion. Wow, when I first pull it out I am surprised by the sheer weight of this thing. I put it in the cover and set it on my chair. I go to sit down and nearly needed to call an ambulance because the chair shot out from underneath me causing me to have to catch myself from falling flat on my back. I am no spring chicken so this caused a little physical discomfort that will likely last a week or so before I recover. Here I go digressing again..... So, I grab the chair, slide it back to the desk, try to sit down slower this time while keeping a firm grip on the arms of the chair. Okay, the cushion is pretty thick, maybe I need to lower the chair a little. I lower the chair go to sit down again and nope. I feel like I am sitting on a cloud. You would think that is a good thing, right? Now imagine that cloud trying to buck you off, make you slide, shift, shimmy in all directions at once. I try to adjust and figure out how to get it to quit feeling like my chair is trying to run out from under me or give me one heck of a roller coaster experience. I finally get settled in a reasonable approximation of comfort and settle in for a couple of hours of dungeon crawling and doing my best to unalive every creature I encounter. Within ten minutes I have slid down in my chair to the point I feel like I am being folded in half and my lower back is absolutely on FIRE. Save your money and try something else. This just isn't it. I am sorry Purple. I love your commercials and the gimmick with the eggs. I resisted a long time trying your products and now wish I had kept resisting.
