Description
Description
Built around a contoured cut-out seat, ErgoRelief™ works with your body to
take pressure off your tailbone and hips — the exact spot that starts hurting
20-30 minutes into a desk day. It’s the difference between a cushion that just
feels soft and one that actually changes how you sit.
What's included:
● ErgoRelief™ Seat Cushion — ergonomic cut-out design, memory foam with breathable mesh, removable washable zip cover, non-slip base and universal fit.
● The SitComfort 7-Day Reset Program (guided)
• Backed by a 30-day money-back guarantee
Designed in Australia for people who sit 6+ hours a day and are done compromising on comfort.
7-Day Reset Program
7-Day Reset Program
It's the difference between a cushion that feels good for a day and a system that fixes how you sit for good.
The 7-Day Reset Program is a guided, day-by-day plan included with every ErgoRelief™. Each day takes a few minutes and builds on the last — small posture cues, stretches, and setup adjustments that retrain your body to sit better, not just softer.
How it works:
● Day-by-day guidance delivered straight to your inbox — no app, no login, no fuss
● Simple, physio-informed movements and posture checks you can do at your desk
● Built to work alongside your ErgoRelief™ and LumbarEase™ set-up
● Takes 2–3 minutes a day
By Day 7, you're not just sitting on a better cushion — you're sitting better, period. That's the difference between temporary relief and a lasting fix.

Why ErgoRelief™ Feels Different
Softness isn't the fix.

Why One Product Isn’t Enough
Pressure off your tailbone
The contoured cut-out keeps your weight off the spot that starts aching first.
Your lower back keeps its curve
The lumbar support holds it there, so you're not holding it with muscle all day.
One makes the other work
The seat sets your hips at the right angle — which is what lets the lumbar support do its job.
Then it sticks
The 7-Day Reset retrains how you sit, so it holds when you're not thinking about it.

"The cushion helped straight away, but the 7-Day Reset showed me how to set everything up properly. After a few days, I stopped shifting around as much."
“The lumbar support is the best I've ever used. It doesn't flatten out like the cheap ones from Amazon.”
“The daily video cues were the missing piece. It's not just about the cushion; it's the habit training.”

Frequently Asked Questions
Really comfortable for long stretches of sitting. I'm often at my desk for 10-12 hours a day. Love that the memory foam is soft and moulds nicely to my shape. It definitely delivers on the pressure relief it promises — no more sore tailbone by the afternoon.
Also being anti-slip but not attached to a backrest is a big plus for me, since I shift forward a lot during the day. With this, I can just slide the cushion with me instead of being locked into one position.
I use this with the LumbarEase back support and it's really made long sitting sessions so much more comfortable and eased my back pain.
I love my ErgoRelief cushion! I set it up on my office chair and it is so comfortable. On Fridays I sit at my desk all day and I used to get lower back pain and just had a very tired and restless lower body. The cushion not only takes the pressure off my tailbone and relief the ache, it also encourages me to sit properly without crossing my legs or leaning in all sorts of wrong ways. This really helps me with supporting my posture as well and spine alignment. I use the cushion in combination with the Lumber support cushion and it complements the seat perfectly as I lean back and have the support for my back.
Great quality cushion! It feels very supportive and has definitely improved my overall sitting comfort. Highly recommend.
I used this in car and this is big help, I am driving a lot.
I wasn’t expecting a huge difference at first, but after a few days I started noticing I wasn’t shifting around as much in my chair. It’s actually really comfortable without feeling too soft, and it kind of encourages you to sit properly without thinking about it. I work long hours at a desk, so that made a big difference for me. Definitely feels like better support than just using the chair on its own.
Extremely impressed with Sit Comfort, the seat and back cushions have levelled up my home Office. For to long was I uncomfortable and sore. Now having use of it daily, it has helped my wellness, mood, posture and productivity at work. Love it and highly recommended the products!!
The ErgoRelief Seat Cushion is very comfortable and provides excellent support. It helps reduce pressure and discomfort when I sit for long periods. The quality is great, and I’m very happy with my purchase.
Great
Perfect back and spine support for long hours at work
Probably my favourite one out of the two that I got. It sits nicely underneath you and provides good support for long office days. It has grips so you don’t slide which can occur sometimes depending on what you wear but not enough to be bothered by it. It doesn’t slide off the seat though it’s secure. Would recommend for people needing better seating support, especially those who work from home like me.
Made of great material, instructions to wash are straight forward. Feels nice and warm as if seating in a slightly heated pad (great for the current wintertime).
High-quality foam that does not deform after a day's of sitting on it.
The seat cushion is soft and relieves pressure on my lower back and hips, perfect for sitting long time !!!
Extremely comfortable if you're sitting for long periods of time it wanting to make your chair extra comfy!
Makes a huge difference instantly as soon as I sat down. I feel so much more supportive and wished I had purchased this sooner
Highly recommended. It is bery comfortable.
