Fantastic for Recliner!!
Okay, sorry this is so long, but I'm going to compare the Ultimate to the Purple Royal, RoHo, and Purap for a recliner and computer chairs. I hope it will save someone from having to buy a bunch of different cushions for trial and error. I bought the above cushions for my leather Lazyboy recliner because the seat cushioning has flattened over the years, but the recliner itself is still great. The Purple Ultimate is THE ABSOLUTE BOSS in a recliner. I sometimes do embarassingly long movie marathons on my days off, and can legit sit for 12+ hours with the Ultimate cushion. I have tried both an air filled RoHo and a Purap cushion in the recliner. Neither came close to the Ultimate. The Royal would probably work in the recliner, but I haven't bothered to try it because the Ultimate is just that good. My Purap was passably comfortable for about 8 hours in the recliner, but got destroyed because it couldn't hold up to the punishment of extended couch surfing sessions. I fear the same is probably true of the RoHo. The Ultimate cushion is amazing for this purpose. Now let's talk computer chairs. I have lumbar, tailbone, and restless leg issues when I sit too long without the proper "cushioning" or alignment, so I use a Humanscale Freedom computer chair. Now keep in mind that the Freedom chair is highly ergonomic, which might make cushions act a little differently because it forces you to sit upright and aligned over the top of your hips (it's way more comfy than it sounds). This chair has a comfortable, but "hard" seat that slopes in the front where your thighs sit. I am also talking about extended sitting with only getting up to go to the restroom (e.g., extended computer gaming session). The RoHo cushion absolutely slays all other competition in a hard seat computer chair. I have been able to work all-nighters on the RoHo without any significant discomfort. The Purap was okay in my computer chair for about 4 hours (but would probably be fantastic in a wheelchair or softer computer chair). The Purple Ultimate was okay for about 5 hours, then the restless legs kicked in...I think it's because there is no downward sloped edge where your thighs sit. My lumbar still felt great though, so I guess it depends on what symptoms you're trying to minimize. The Purple Royal is definitely the 2nd best for my computer chair, but restless leg starts to kick in at about 7 or 8 hours. So, if you are looking to cushion a seat that doesn't have much give, go with a RoHo air filled cushion if you sit for very long periods and your chair forces you to sit upright/have decent posture. Go with the Purple Royal if you have a hard seat and sit for very long periods but do lots of stand up breaks OR sit for medium-long periods without breaks and sit with upright posture. The Royal would probably also work in a hard chair if you sit for very long periods, but with more slumped or relaxed posture (e.g., aren't sitting right over your hips). If you will be sitting in a "soft" chair, the Purple Ultimate is hands down the winner, no matter how you sit. For long periods in a vehicle, I think the same rules above would apply, but tbh, I haven't actually tried, so am just imagining based off my experiences. I hope this helps! :)

Purple seat cushion pushes all the proverbial buttons
I ordered this seat cushion and got it yesterday. 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 amazon. It's a lot better and bigger (width wise) cushion on amazon. 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 amazon 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.

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.

Extremely Happy
I've had long-term sit bone pain along with back pain. I tried a lot of seat cushions, but none gave me satisfactory relief. Finally, I found the Purple Ultimate Seat Cushion and decided to give it a try. As soon as I put it on my office chair, I felt relief right away. It's an amazing product! I can sit on it all day without any butt pain. There are no pressure points on my bottom, and it really distributes the pressure, alleviating my chronic sit bone pain. Even though my ErgoTune Supreme Ergonomic office chair provides great back support, its seat is a bit hard. This cushion has really helped relieve my sit bone pain. I'm extremely happy with my new Purple Ultimate Seat Cushion—it's the best seat cushion I've ever used.
