#1 Ortho-Recommended Car Seat Cushion
Your lower back curves. Every seat is flat. So every hour you sit, all your weight jams your tailbone into the seat while nothing supports your spine.
The OrthoBase fixes both at once. The hole keeps your tailbone off the seat and spreads your weight across the entire cushion. The raised back fills the gap behind your lower back, so the slouch and the pain never start.
Test it for a full 60 days, in your truck, your car, your chair. If your back doesn’t feel the difference, send it back and we’ll refund every penny.
SUITABLE FOR: Truckers, drivers, and desk workers whose back, tailbone, or legs start hurting by hour 3 of sitting.
FEELS LIKE: Firm, supported relief the second you sit down. Not soft like cheap cushions, not hard like your seat. Back, butt, and tailbone supported at once.
HOW IT WORKS: The hole keeps your tailbone off the seat. The raised back stops your spine from sinking into it. Less pressure, less shifting.
PERFECT FOR: Anything from a 3-hour sit to a 10-hour drive. Any seat that leaves you numb, stiff, or sore.
FREE FROM: No flat foam. No flimsy comfort pad. No “just stretch more.”
You have 60 full days to test it in your truck, your car, your chair. If your back doesn’t feel the difference, send it back and we’ll refund every penny. No questions asked.
You either love sitting again, or it costs you nothing.

Dr. Matthias Müller, MD, FAAOS
"Most of my driving patients were told to adjust the seat. You can't adjust a flat seat into lumbar support. An hour in, the lower back is hanging and all the weight sits on the tailbone. OrthoBase fills that gap and lifts the tailbone off the seat. That's why my patients keep the car instead of selling it."
You don't have a back problem. You have a seat problem.
The Problem + Cause
The Car Seat Is The Reason For Your:
Back Pain
+
Every hour you sit, that gap lets your spine slump and your discs take the load your seat should be carrying. That's why the ache starts a few hours in and follows you home. OrthoBase fills the gap, so your spine keeps its natural curve at hour ten, not just hour one.
Sciatica
+
The sciatic nerve runs right under the muscles you sit on, and a hard flat seat presses on it for hours at a time. That pressure is the numbness, the pins and needles, the pain down the back of your leg. The center cutout and contoured base move the weight off the nerve path instead of crushing it into the seat
Butt & Cheek pain
+
Flat seats press your full weight onto two small sitting bones. That's the aching cheeks, the numbness, the nonstop shifting. The contoured base spreads the weight so no single spot takes it.
Motor Vehicles Seats are the worst enemy For your lower Back
A one-time purchase that relieves tailbone, back, and hip pain without draining your wallet.
But Why OrthoBase?
Because it worked!

Frequently Asked Questions
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?
+
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?
+
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?
+
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. All the stretching will be undone when you continue sitting with bad posture hours every day.
Isn't this just another seat 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?
+
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.
