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.

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.

I was fortunate to be able to "test" sit at a Purple store near me, if able to try out for yourself first before buying, I would reccomend you do so. I was initially wanting to buy the Royal one, but after sitting on one in the store, it was not near as soft for my needs. I sat on this Double one and it was perfect. I have a fused back, with three vertebrae fused at my lower back with 6 screws and plates, I had bought a brand new Ashley Furniture brand office chair that seemed comfortable enough when I tried it out at the store, but for sitting for 7 hours plus a day, ended up being very uncomfortable and required frequent getting up and moving around. Rather than return the chair and invest in a super padded, very expensive Big N Tall one that would likely work for me, I thought I would try this option first. I am happy to report it made a night and day difference for my repaired back and I can comfortably sit all day in my office chair, and my back and rear end are extremely thankful for my purchase of this cushion. It is pretty heavy, but this is to be expected for a dual thickness Cushion, it is not overpowering but it does have some heft, and would likely be a bit of a nuisance if you wanted to carry this around for different seating situations, but is doable. It did have some smell upon opening as others have commented on, but it was minor and not overpowering. I just put it in my bathroom and opened the window for 24 hours. It fits snugly in the cover, I have mine smaller honeycomb side up (part you sit on) , and larger side down on the chair (as suggested). It does move around a bit on my office chair as some have also made note of. I will try some grip tape and see if that makes any difference. I am very happy with this Cushion so far, it fits the bill for my needs, and is very comfortable, it does compress quite a bit while on it, so the double thickness is not a issue for me as far as raising me up on the chair, I am 6'2 and over 200 pounds for reference, someone smaller and lighter may experience a bit of a lift in the chair while sitting on it. **Exceeded my expectations, as a side note the same Cushion in the actual Purple store cost $50 more than here on Amazon, and salesman said they would not match online prices even though this Cushion ships direct from the actual Manufacturer, so try on in store if possible, then buy here on Amazon to save $$.**

I don't spend money just for the sake of spending money, but I think this is one of the products that's worth buying the name brand. Several months ago, I tried a knockoff of the same type of cushion (grid, etc.) that was about 1/3 of the cost and the entire month I had it I was debating whether or not it made enough of a difference to justify keeping (I returned it). With this one from Purple, as soon as I sat on it the first time, I knew I'd keep it and still feel the same way about it after using it a while. I deducted half a star because I think it's somewhat overpriced, even with buying it on sale. I deducted another half star because it doesn't stay in place quite as well as I would like, especially considering the price. It stays in place moderately well, and it would probably do a bit better on some chairs than the one I have, though I can imagine it doing worse on some other chairs too, but I still have to slightly reposition the cushion every time I sit down if I need or want it to be in the "right" place. I've now been using this cushion for a month - long enough to feel qualified to say it has significantly improved my ability to sit and work at my computer for extended periods, but I haven't owned it long enough to offer insight into the longevity. It feels like it'll last a while, but only time will tell. I've also been using the cushion exclusively at my desk, but when I'm able to get back out on the road for some long trips in my van, I'm looking forward to using it there too. If it was cheaper, I'd probably buy a second one to keep one in the van and one at my desk. With my specific issues, on a good day, I used to be able to sit at my computer for up to maybe two or three hours total before the pain would be bad enough that I had to be done for the day, but with using this cushion I can go about three times as long. Sitting at my desk for sometimes several hours at a time, I don't know how to gauge the cooling effect, but I certainly don't get a hot butt. I had considered the next step down from this model, the "Office Chair Upgrade", but based on my experience with the other cushion I tried, I knew I wanted one that was big enough to cover the entire seat of my chair and that first one wasn't big enough. When I got the that one, I didn't think it would make as much of a difference as it does for me to have the cushion cover the full seat. The "Ultimate" is big enough to cover the seat side to side on my office chair and only falls a little short at the front edge, which is fine for me. Since my chair has a contoured seat already, I might have preferred a completely flat cushion, but not at the expense of size. For those who haven't tried cushions like this before, it's worth mentioning how it's going to affect the seat height and how that extra height could end up being positive, neutral, or negative. When I tried the knockoff, I wasn't thinking about how much it would change the seat height and it was a little surprising. But, I'm also a bit of a stickler when it comes to ergonomics, especially with some of the physical issues I have. Someone who doesn't need things to be as dialed in will be less affected. At my desk, I think the added height is an overall slight net positive: I'm tall enough to compensate for the cushion by adjusting my seat height without bottoming it out and since the armrests on my chair aren't adjustable, it slightly improves that for me so I'm using better posture and arm position for typing. For someone shorter, it could be the case they'd need to plan on a footrest or something to maintain proper ergonomics. In my van, though I haven't used it there yet, I expect it's going to be a solid positive because, while I'm tall enough that I'm not bottoming out my office chair even after adjusting it to compensate for the cushion, I'm short enough that the seat in my van (Ford E350) isn't comfortable for me for long trips since it isn't adjustable. This will give me the extra seat height there that I want there.

This made a long car trip comfortable. I was also cooler and less sweaty. 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.

I would just like to start out saying that Purple's customer service has been amazing! Jeni specifically was the representative that helped me and she was very attentive and responsive to my concerns. When the cushion arrived there seemed to be a few splitting marks at the edge of each side and when I showed photos she went ahead and sent me a replacement. I also did not need to go through the hassle of returning the defective one. I've used this cushion now for about two months and I've tested two other cushions from amazon (knock off's) as well as the ultimate and royal cushion from Purple, both of which weren't for me since they were extremely too firm. I am around 125lbs and petite, so unfortunately they both felt like i was sitting on a wooden chair. The knock off's were extremely thin and it was like i was using nothing so i returned those as well (learned that not all gel cushions are made the same). For the double cushion, it was the only one that made me feel a difference! It is plush and actually DID something. I am using it on a office chair handed down to me that has lost its cushioning so it was like sitting on cement, I needed something to hold me over before i can buy another office chair, and for me the double cushion sufficed. Now it didnt change my life and take away the pain completely, as I unfortunately still feel pain in my lower back/tailbone (but that could also be because of no lumbar support from my office chair so i don't want to put the blame completely on the cushion) and after 30 minutes to an hour of sitting i do have to reposition myself or stand up from my chair as I still do feel pain. That being said, it is usually recommended to get up and move around every 20 minutes or so of sitting so with that in mind it may actually be helping me! Using the cushion with an office chair that has more cushioning than my current chair may improve its efficacy though. I am using the smaller waffle side up and the larger side down, I believe they state for harder surfaces you should be using the smaller squares on the bottom but i felt more cushion with it facing upwards. Our bodies are all so different, so this may be comfier for you than it was for me or it may do nothing, so I would suggest trying it and then deciding! Hope this helps!

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! :)
