See It In Action
Your lower back curves inward. Every seat you sit on is flat. That leaves a gap behind your spine that nothing supports, so all day, your discs strain to fill it while your full bodyweight bears down on your tailbone. Over time your discs compress and the natural cushion between them wears down.
If you sit more than 3 hours a day, this orthopedic set was made for you. It unloads your discs and sciatic pressure and fills the gap behind your curved spine, so every chair becomes the right fit for your lower back.
Most people hesitating aren't worried about the price. They're worried this will be one more thing that doesn't work. So test it in your own chairs, at your desk, in your car, for a full 60 days. If your lower back doesn't feel the difference, send it back and we'll refund every cent.
Support you can feel while sitting, not another cushion that gives out fast. Here's what Spruka users reported:
Based on a 30-day survey of 412 verified Spruka users · January 2026.
If your lower back doesn’t feel the difference, send it back within those 60 days and we’ll refund every cent. No forms to fight, no questions asked.
You either love sitting again, or it costs you nothing.
“Long sitting loads the tailbone, hips, pelvis, and sciatic pathway. Spruka’s Orthopedic Sciatica Support helps unload that pressure, improve sitting tolerance, and make everyday chairs feel safer. That’s why my patients love it.”

“A good seat support should do more than feel soft. It should help stabilize the pelvis, reduce shifting, and support the body through long sits. That’s why I recommend Spruka’s Orthopedic Sciatica Support.”

End Back Pain From Sitting
A chair starts hurting you at minute 30. Twenty minutes of driving lights up your leg. By 3pm you're shifting like the chair is made of gravel.
Every fix you've tried pads the tailbone. None of them unloads it.
The Spruka™ Cushion's U-shaped cut-out takes your tailbone out of contact. Not less pressure. None. Foam moves your weight to the two sit bones built to carry it, so your legs stay awake on hour three.
Problems that Spruka Fixes:
Most chairs leave a gap behind your lower back. Spruka™ fills that gap, restoring your natural curve and reducing muscle strain during long hours of sitting.
Uneven weight can stress your hips and joints. Spruka™ distributes pressure evenly, helping you maintain balanced posture and reducing hip strain.
The tailbone cut-out takes pressure off your tailbone, spreading weight across the cushion so you don’t feel that sharp, burning pain after minutes of sitting.
By keeping your hips level and spine upright, the cushion eases pressure on the sciatic nerve, so you can sit, drive, or work without that shooting pain running down your legs.
20x Cheaper Than Costly Fixes
Most people spend thousands trying to fix sitting pain:
Ergonomic chair: $800-$1,200
Weekly chiropractor visits: $75-$150 per session ($3,000+ per year)
Physical therapy: $200+ per session, often weeks of appointments.
Orthopedic Sciatica Support Cushion
A one-time purchase that relieves tailbone, back, and hip pain without draining your wallet.
Relief That Adapts Wherever You Sit.
The Spruka™ Cushion adapts anywhere you sit: the car seat, the office chair, the dining chair, the wheelchair.
The non-slip base stays put. No sliding around, no readjusting a dozen times a night, no rubber mat from the kitchen cupboard to hold it still.
High-density foam holds its shape instead of packing flat in a month. The cover comes off and goes in the washing machine, so it stays clean through daily use.
Use Spruka’s Orthopedic Sciatica Support daily for 60 days. It must make your seat feel more supported, easier to sit in, and less punishing on your back, hips, tailbone, or legs.
If it doesn’t help you sit longer without paying for it later, refund it.
Full refund. No questions asked.
Frequently Asked Questions
Is it only for truckers?
Is it only for truckers?
No. We built it tough enough for truckers sitting through 11-hour drives, but it’s made for anyone whose body suffers from long sitting. If your chair hurts your back, hips, tailbone, or legs, this was built for you.
Can I use it every day?
Can I use it every day?
Yes. Use it anywhere you sit for long periods, behind the wheel, at your desk, at dinner, or on the couch. It’s made for daily sitting support.
Will it help with sciatica?
Will it help with sciatica?
It helps unload pressure from the tailbone, hips, pelvis, and sciatic pathway — the exact areas long sitting tends to punish most. It is not a medical cure, but it is built to make sitting feel safer and more supported.
Why not just stand up and stretch?
Why not just stand up and stretch?
Because some people can’t. Truckers, drivers, office workers, and anyone stuck in a seat for hours need support while they sit — not advice that only works after the pain starts.
Is this just another cushion?Is this just another cushion?
Is this just another cushion?Is this just another cushion?
No. Most cushions are soft pads that flatten under your body. Spruka’s Orthopedic Sciatica Support is built to unload tailbone and sciatic pressure while supporting your hips and pelvis through long sitting.
What makes it different?
What makes it different?
Spruka was built around the reality of long sitting: pressure builds, pain spreads, and your chair can follow you long after you stand up. This support is designed to reduce that seated pressure before it steals the rest of your day.
I was very skeptical when I got mine, but I’m here to tell you it’s freaking changed my life. I got a bony ass and a bad back and I finally learned that the hard leather seats in my truck are why my back’s been hurting.. this cushion right here has relieved all my pain in a matter of days. I recommend this especially for CDL truck drivers that drive 11 hours a day.
Have a herniated disc and very very bad sciatica. Just received it today and it felt weird at first since I’m not used to back support like this, but within 20 minutes I felt much better. Less pain overall. Will continue to see how this cushion feels after 2 weeks, but so far so good.
I have severe pain in my tailbone and hips and it doesn’t help that my chairs are all hard (mainly wood). I’m ~280 lbs and 6’5 so I was skeptical about if it would fit bigger butts and actually be supportive enough for me. Lucky for me, it was. After about 5 days my pain had vanished and I bring this everywhere I go now! Will buy another one for my brother since he’s a trucker and sits 10-11 hours a day.
I commute to work which is about 3-4 hours a day and I’ve started suffering from low back pain and sciatica. Gave this a shot and it works! Sitting in traffic and driving on it feels really nice on the back and butt and it’s really comfy, like you are riding on a cloud. No longer feel pain or numbness
Outstanding! I use this now exclusively in my wheelchair. It's formed perfectly to provide support. It is thick and strong enough to hold its shape. Yet it is soft enough to be comfortable. It stays in place! No constant shifting and adjusting. Easy to remove and put back on when desired. No need to be fussing with a bottom cushion and back cushion and a lumbar support cushion. I love this all in one, shaped cushion.
Excellent orthopedic memory foam cushion. It is very comfortable and provides great relief for my lower back and tailbone. Since I use it, I can sit for longer without discomfort. The foam is firm but comfortable, and the cover is easy to clean. Very good quality and totally recommended!
I spend a lot of time sitting at a desk and this cushion and have developed back pain because of it. This memory foam is supportive without being too firm, and it helps me sit without pain for longer periods. One thing I was concerned about before purchasing was whether it would hold up to my weight. I weigh 273 pounds, and I am happy to say that the cushion provides excellent support without flattening out. For anyone looking for extra comfort while sitting, especially if you spend long hours at a desk or are looking for support at a higher body weight, I would definitely recommend giving this cushion a try.
Love this! This is a game changer for sure! Had broken my tailbone due to a snowmobile accident and with this, I am able to sit for longer periods of time, as it has the opening for the tailbone, so there’s no pressure on the tailbone. It is also super comfortable. I have one in my car to drive and another one for my office at work.
I was dealing with severe lower back pain and sciatica and this has eased my pain completely! It is nice looking and very comfortable, like sitting on air. I normally use it on my car, sometimes I will take it to our baby’s reading/play room use it as a floor chair to read story books for them.
I just received my sciatica seat cushion yesterday while I WFH. I loved it from the moment I sat down. I sit for long periods, and I’ve been dealing with severe sciatica pain and tailbone discomfort. This cushion has made a noticeable difference—my posture has improved, and for the first time in a very long while, I felt comfortable sitting at my desk. I’m extremely satisfied with this purchase and plan on buying another one for my car.
I bought it for my ergonomically-enhanced, electronic recliner. Even so, my back has been uncomfortable since I got the chair, even more so as I lost a significant amount of weight. I am a mildly arthritic 70 years young, 5'1 tall, weighing in at about 100 lbs now, which left little natural padding, and sitting was putting stress on my tail bone. I chose this product mainly because it has not only the seat pad, but the little part that encompasses my lower back as well. I also liked that there is a small cut-out that would hopefully take the pressure off the source of discomfort. I know it's really early in the assessment process, but I just sat in this recliner including the cushion, for the past hour and a half in complete comfort! If it holds up over time, my 5-star rating will stick, and I hope to enjoy this for a long time to come. I'm very happy with this purchase.
I really wanted this product to work because I've been dealing with sharp low back pain for years. My PT told me that it would not be possible to force my spine straighter through will power alone and that I would need some additional lumbar support, so I got this. It did feel very strange for the first few minutes and I thought the back wasn't going to be high enough but in a very short time it became very comfortable. Best of all, over the next few days, my back pain receded and eventually disappeared. Highly recommend!
Bought 2 of these, 1 for me and 1 for my wife. This is a great seat cushion with a cushioned seat back as well as a memory foam seat cushion. I have used seat cushions before, but the seat back provides a whole new level of support and comfort. I sometimes sit at my desk for 8 hours or more and get a back pain in my lower back. The memory foam allows enough back support to really help provide pain relief.
The cushion is wide enough to provide good support but still small enough to fit in both of my computer chairs. The material seems durable and tear resistant, and so far it has held up well.
I am very pleased with this purchase.
As a truck driver, I spend 10–12 hours behind the wheel most days, and my lower back used to be killing me by the end of a run. I've tried a few cushions before, but this one is the first that actually feels supportive. The tailbone cutout really makes a difference, and the built-in back support helps me stay comfortable on long hauls. I've been using it for three weeks now and don't leave home without it. Definitely worth it for anyone who drives for a living.
Its very comfortable & well worth it
it's working out pretty well. The comfort difference is notable.
Works well
extremely comfortable went on a 2 hour drive and i usually have a sore and stiff back but i got out of the car with no stiffness or soreness
The box arrived damaged and the cushion was a little deformed
Edit: Customer service reached out to me and shipped me a brand new one free of charge! A+ customer service 😃 would change this to 5 star if I could
I like my memory foam extra extra firm and this is more of a balance between firm and soft. Would probably be comfortable for most people but I'm a bit of a sadist lol. Do like the shape, just hope they have a firmer version come out.
Seat cushion is comfy and helps with my butt pain, I just wish there was a pink or white color to match my chair.
I bought this for my office chair, and it has been a total lifesaver. The memory foam material is premium quality—it feels sturdy and durable, yet the outer cover is gentle and soft to the touch. It has a great balance of firmness and comfort, and despite its solid support, it is lightweight and easy to carry. This versatility makes it perfect to switch between chairs. It has significantly helped with my spine comfort and relieved my tailbone pressure. Exceptional value for money and highly recommended!
This cushion exceeded my expectations. It provides excellent support and helps maintain proper posture while sitting for long periods. The material feels high quality, and the ergonomic design makes it very comfortable. Highly recommended for anyone looking for added comfort and pressure relief.
It’s painful for me to sit on hard chairs…we take this with us everywhere we go, and, although it’s a little bulky, it means I can sit comfortably in restaurants and in our truck. It’s well-made, and the memory foam is soft enough for comfort and solid enough to give good support. It adds about 2-3 inches, which makes it easier to sit down and get up from lower seats.
Purchased this for my father who is wheelchair chair bound . It relieved the pressure off his tail bone. He gets support on his back and buttocks. Glad to see he is more comfortable.
I bought this cushion for my husband, who spends a lot of time sitting at work, and it has been an excellent investment thanks to its ergonomic memory foam design; it provides very comfortable lumbar support that effectively relieves back pressure after long workdays. The outer fabric is quite soft, breathable, and easy to clean, and the non-slip base works wonderfully, keeping the cushion firmly in place on his chair without shifting. However, on the downside, he found it felt quite firm and rigid during the first few days until it molded to his body; additionally, its thickness significantly raises the seat height, forcing him to readjust his workspace setup.
