Purple Back Cushion, Lumbar Support Pillow for Office Chair, Car Seat

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.

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 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.

ok in short summary: feels firm but is soft enough to sit on an egg and not crack the egg surprisingly. 1.25" thick, supports my 225lb weight, after long sitting perioids in car and office playing games and doing i.t. work, i haven't had tailbone or coccyx strain/pain. and its not heat producing. hav sat in chairs or cushions that trap and generate heat after while. so more in depth thoughts and blabber: i love this cushion more than other cushions. most are foam. but its not hot it breathes. I tried sitting on an egg even tho this is 1.25" not the 2inch and the egg didn't crack. i did it slowly carefully but leaned back and raised my arms and legs to make sure my weight was on my buttocks and this thing is soft enough to conform to the pressure of an egg without cracking it. I'm 5' 6" / 7" and a bit hefty at 225lbs. so i'm not a light weight. granted the egg was in my butt crack which has a ... well crack or space to give, but i tried same thing with egg on a normal couch recliner chair with egg in a sandwhich baggy and that egg cracked and exploded. I slept on this as well just to see. i like firmer and fuller pillows , i'm a side sleeper , and threw this on top of a very thin pillow. its actually firm probably too firm for most people's heads my head didn't sink. this is very supportive of a lot of weight. I sat on this in my car and my office chair and i can tell i'm physically sitting higher like my knees almost hit bottom of my steering wheel in car and i definitely sit a lil higher. so this cushions and raises your body a good inch or so. but soft enough to site on an egg carefully without having issue. I would say its safe to assume if you're lighter in weight the 1" or thinner might support your body. i'm 225lbs and this 1 & quarter" thick supports my sitting weight fine. My office chair and sometimes in my car i get that Tailbone/Coccyx strain and pain. so this cushion , for me, is for providing long term sitting cushion and comfort and relive pressure and pain for me. i do I.T. work and sometimes work on my computer remotely all day, shop all day, and play games ... all in one day so this last week this thing has had a lot of use for one week. I did stretch this thing out and grabbing the ends and pulling apart, this thing stretches good. the material is like a firm jelly material. doesn't feel like typical anything really. but i've enjoyed it. i think this thing doesn't feel as soft as it is but it supports nicely and cushiony enough but feels a lil firm but so far haven't had that pain in my coccyx so i'm happy so far so good and its not hot. i live in houston its like 85-95 but feels like 95-105 with 200% humidity so i didn't want a cushion you feel as being hot and didn't want something that goes flat but can support me since i'm a bit over weight actually and i sit a lot. but no pain in the butt after long sitting period is a double!

After using The purple cushion for approximately seven months now, I believe I can give an honest review. The cushion at first appeared to be very comfortable after utilizing it day after day inside a vehicle you’re going to realize that if you sit for more than 8 to 12 hours on the cushion Pressure starts to accumulate and build on your hamstrings, the cushion is great for your butt, but not very good for your hamstring area. It creates hard pressure due to how thick and hard the cushion is built. Also, it does not stay in place on the chair. You have to remove it from the vehicle on very hot days. I also purchased the smaller cushion, which does not work very well inside a vehicle. It is softer but not as large as this one. Sometimes I find myself removing the cushion and just sitting on the vehicle‘s chair to alleviate the pain underneath the hamstrings. This is probably best for someone that works at home and an office chair or a gamer, but not for someone that drives and sits in a vehicle for long hours. If only purple can come to a solution to fix how your hamstrings sit on the pillow, they will solve this problem and the cushion would be a five star cushion. Hopefully my opinion will help some of you out.

Love this seat cushion. It's so comfortable and takes pressure off my hips & sciatica pain. Where have you been all my life?

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 $$.**

Very comfortable, quality design, can sit for hours with this and no back pain. No S.W.A.S. I use it on top of a subwoofer for a nice spot to sit and play my guitar, it prevents my legs/glutes from going numb even after hours.

Bought it for my brother in law Great for hip and back pain

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.

Best seat cushion I have ever used. Can sit there for 12 hours and you still won’t hurt

Following a Life-changing spine injury, going anywhere in a vehicle was awful, especially potholes and the like. After talking to a lot of people, especially long-distance drivers, the majority of recommendations were for the Purple Ultimate - which was too large for my car seat and hellishly expensive to order on Australia. This is the same thing, but in a slightly smaller size. It is really great at distributing pressure evenly, so there's no pressure points, and also absorbing those sharp jolts from potholes and the like. Recently tested on a 400km trip - my longest in a year - and it was amazing. I've tried the cheapest alternatives and they're rubbish by comparison. As a final vote of confidence, my 85-year-old dad tried it, and ordered one for himself the next day.
