I drove with it today, and here is my review. First, it's the right size for a Ford Bronco. If you've driven in a Bronco, you know that their seats are somewhat comfortable for shorter drives, but sometimes a little hard. But long trips can be hard. I did buy a different cushion in the store on said long trip, and passed on the purple cushion (not ultimate) due to it being twice the cost. However, the shortcomings of that cushion was it was too small. I then got another cushion on desertcart. It's a lot better and bigger (width wise) cushion on desertcart. The quality is pretty good, but again, it was too small for the Bronco seat, and it came up short under my legs and sides. Though, I like the feel on my behind. I can even sit on my wallet which is big and bulky, and not feel it. I finally measured my seat (got the tape ruler out), and found that the ultimate purple looks like it may fit. The purple cushion is the right size width. It's wide enough for my seat so that my body isn't spilling over the sides, and it comes up under my knee right where the calf turns down. It's the same thickness as the desertcart bought cushion, but since it fits better on the seat, it seems taller (maybe it is?). Anyways, I almost feel like it's too tall, but I can't argue with the cushiony feel on my behind. Wish list for purple: 1. offer straps to secure to the car seat. It's heavy enough to almost not shift, but it does shift a little when getting out of the car. This is a small annoyance. My other two cushions are annoyances. 2. Maybe taper the front a little bit. Make it more of a wedge. Maybe if I got this wish, it might not work out. I think it's worth trying, though. 3. Get rid of the spine cut-out. I fee like I'm being pushed down on the rear, and the front of my legs lifted up. Kinda exaggerating a little, but just a little. As mentioned before, although it's 2" in height, it feels like it's taller than the other 2" cushion that I got prior. I'm not sure if it's really taller, or maybe because it fits to my knee, maybe that's what's making it taller? Also, it seems with the added height, that I had to adjust the mirrors to the height. It also makes looking at the street traffic lights a little bit more challenging. Would I go back to other seat cushions? Or use no cushion at all? Not on your life! Even with these "flaws", it's the best seat cushion that I've been able to find (so far). If I could have just one thing, it would be to get rid of the cut-out for the spine. I don't think it's needed. update: loving this seat cushion. I turned the seat cushion around so that the spine cut-out is now in the front. I think it fits a little better in the Bronco seat, and my behind is a lot happier. The spine cut-out is between my legs now, so it's not really an issue anymore. Maybe a leg might drift into that area fit better? I dunno. I feel like that's the "taper" I was hoping for, kinda. Review: It's worth the price and that's saying a lot! - At $127 on sale, I really wanted this cushion to not live up to the hype...but, dammit, it exceeded the requirements I set in my head to be worth keeping. I've owned many, many seat cushions in the past decade since hurting my back. If I were to add them all up, I've easily spent more than $200. I've tried many formed memory foam with the coccyx cutout and a few honeycombed gel cushions that are pretty much imitations of the Purple Double. They've all helped, but they've also had some things lacking. The honeycombed gel pads all bottomed out, while providing some relief, and that bottoming out caused pain after a few hours of sitting. This Purple Ultimate relieves all of the pressure and it feels like I'm floating on a very comfy and resilient cushion. It is thick and heavy, being made from the same blow molded polyeurethane as the Purple mattress, in three layers with different supportive design laters. So, being made from the same stuff as the mattresses, this is a heavy cushion. Carrying it on an airplane would be a chore. Also, it is very wide; the widest cushion I've ever owned. These sound like I'm building to a negative review but I'm not. Its totally worth the hassle. I highly suggest ordering one to try it out for yourself. Its a game changer. That being said, I also ordered the Purple Double. That isn't worth the expense. It is made out of the same gel as the much cheaper $25 gel honeycomb cushions and it feels exactly like them. It is NOT worth the $111. That one will be getting returned. UPDATE 4/20/2026: This cushion had lost no cushioning or form. It has not degraded in any way. It is my goto cushion. It's usually in my car, but I move it around if I I'm going to sit in my office chair fir a long time, whenever I have to sit on a hard plastic or folding chair, sometimes on my recliner if I'm experiencing bad back pain. If it wasn't so expensive I'd have multiple ultimate purple cushions all over the place. I'm now faced with a dilemma. I'm going to Japan soon. That's a 16 hour flight. I've lost 2 cushions while traveling in the past. I don't want to lose this one, but my second best cushion would leave me laid up in bed in the hotel, unable to enjoy my vacation for the first 2-5 days I'm there. So, I'm going to take the ultimate Purple cushion , and I think I'll tie a paracord between the cushions handle and my backpack handle. That'll solve the problem on the plane. I'll have to figure out some way of not losing it in taxis, trains, hotel luggage storage areas, etc. If I lose it, I will definitely buy another, but I'll have myself for losing such an expensive cushion. It is just that effective. ## Features - 92% Polyester Fiber, 8% Spandex Fiber - LUMBAR SUPPORT FOR LONG DAYS: The Purple Back Cushion molds 100 percent GelFlex Grid to the curve of your lower back, supporting posture and easing pressure so you stay comfortable through long days at your desk, in the car, or in a gaming chair. - ADJUSTABLE STRAP FITS ANY SEAT: A strap and buckle hold the back cushion in place on office chairs, gaming chairs, car seats, and recliners, no sliding.

It gives good support and seems like it will hold its shape well. The size was perfect for the car seat, if placed with the shorter sides at the front and back of the seat. It laid flat that way. Note: you shouldn't leave this on your car seat if the car will get over 100 degrees. So you'll need to move it to a cooler place in your car if you leave it in the car. Since this is fairly heavy to carry around, I don't think I'll use this on an airplane. ## Frequently Bought Together - Purple Back Cushion | Pressure Reducing Grid Designed for Ultimate Comfort | Designed for Chairs, Gaming, and Travel | Made in The USA - Cushion Lab Patented Pressure Relief Seat Cushion for Long Sitting Hours on Office & Home Chair - Extra-Dense Memory Foam for Soft Support.
