OrthoBase ™
Your lower back curves inward, and every seat you sit on is flat. That gap is what leaves your discs straining. The cushion fills it and unloads the pressure.
See It In Action
Lower back support pillow designed to ease discomfort in your lumbar region, buttocks, and coccyx—ideal for vehicles, workplaces, and residential spaces.
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.

Orthopedic Sciatica Support Cushion

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
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.
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.
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.
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.
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.
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.
