Real people. Real relief.

Description

Most "ergonomic" cushions treat the symptom. The ComfortBundle™ treats the cause.

Built around a contoured cut-out seat and a contouring lumbar backrest, the ComfortBundle™ works with your body to take pressure off your tailbone and hips, and gently guide your spine back into proper alignment — the two things that turn an 8-hour desk day into a genuinely comfortable one.

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.

● LumbarEase™ Backrest — contoured lower back support, memory foam, breathable air-flow mesh, adjustable dual straps and removable washable zip cover

● The 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

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 free with every ComfortBundle™. 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 [the full system] works

Why the full system works

Most people fix one area and ignore the rest. Full comfort comes from supporting seat and spine together — then reinforcing better habits over 7 days.
Hips, lower back and spine in one line
Pressure off your tailbone

Pressure off your tailbone

The contoured cut-out keeps your weight off the spot that starts aching first.

Your lower back keeps its curve

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

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

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."

Sarah L. Verified customer

“The lumbar support is the best I've ever used. It doesn't flatten out like the cheap ones from Amazon.”

Mark T. Verified customer

“The daily video cues were the missing piece. It's not just about the cushion; it's the habit training.”

Frequently Asked Questions

Most of them — office, gaming, dining and car seats. ErgoRelief™ sits on any flat seat. LumbarEase™ has adjustable straps, so it fits backrests with or without built-in lumbar support. They work best on a chair with a flat seat and a backrest you can strap to.
Most people feel the pressure come off the first time they sit down. Full comfort usually takes a few days. Sitting properly uses muscles you haven't been using, so a short adjustment period is normal — it isn't a sign it isn't working. That's what the 7-Day Reset is for. One short video a day, each building on the last, so the change sticks instead of wearing off.
Firm — deliberately. Soft cushions feel great for ten minutes, then bottom out and put you straight back on your tailbone. High-density memory foam holds its shape, so the support at 5pm is the same as it was at 9am. If every lumbar support you've tried has dug into your back, that's usually a too-thick one on a chair that already curves. LumbarEase™ is contoured to sit in the gap rather than push into it.
A short video each day, plus the setup and habit changes that go with it. - Day-by-day video guidance, one per day - Practical setup tips for your chair, desk and screen - Simple movement and posture routines you can do at your desk Each day builds on the last, so by the end you have a setup and a routine that hold without you thinking about them.
It's emailed to you after your order — no app, no login. Each day is one short video and one adjustment to make, about 2–3 minutes.

I’m very happy with the ComfortBundle Complete System. It is comfortable, supportive, and feels well made. It has made sitting much more comfortable for me. I’m very pleased with my purchase and would definitely recommend it!

Remi Davids

My absolute favourite has been the Lumbarease Back Pillow. I’ve found that it has really helped me be more intentional about maintaining good posture while sitting, especially during long periods at my desk. The cushion is soft, supportive and feels really comfortable against my back.

As for the Ergo Relief, I’m still getting used to it and figuring out the best way to incorporate it into my sitting routine. I think I may simply be accustomed to sitting on a flat surface, so it’s taking a little adjustment. I’ll definitely continue using it to see how I go.

Overall, I’ve really enjoyed trying the products, particularly the Lumbarease, and I can already see how it can be a great addition to a work-from-home or office setup.

Wendy Cheung

Got these two together and they've genuinely helped with long hours of sitting.
The ErgoRelief seat cushion is soft, moulds to your shape, and the anti-slip base means I can shift it forward when I lean forward during the day — it's not locked to the backrest so it moves with how I actually sit.
The LumbarEase back support is just as soft and moulds to the curve of your lower back. I've had scoliosis since I was young, so lower back fatigue is a regular issue for me, and when I do sit back into it properly, the relief is really noticeable.
Having set just means I have support throughout the day, however I'm sitting. They work really well together.

Wendy Cheung

This one's really made a real difference for my lower back. I've had scoliosis since I was young, so lower back fatigue is something I deal with a lot — when I do sit back into this cushion, it moulds to the curve of my spine and genuinely eases the pressure. I don't always sit fully back (I tend to lean forward through the day), but whenever I do use it properly, the relief is noticeable. I use it alongside the ErgoRelief seat cushion, and having both just means whichever way I'm sitting, something's supporting me. Love it

W
Wendy Cheung

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.

Being using the bundle for about 10 days, and noticeably have less hip tightness after a long day of meetings (although I have an alarm on to remind me to get briefly up every hour).
The material is good, although I felt a bit like seating on a heated pad in some occasions (not a bad thing as it is wintertime now), so curious to see how the seat will behave on that matter during the warmer months.
I feel like having the ComfortBundle is saving me from having to invest in an expensive office chair for home, allowing adapting the one I have for much more comfort and support whilst working from home.
WIll continue using it, and definitely recommending to family, friends, clients, neighbors.
Thank you

Giane Caon Camara

I have used the LumbarEase lumbar support for 10 days now.
Easy to unpack and fit in my home office chair.
great breathable material, it did not make my lower back feel hot but nicely supported in its lordotic curve.
I haven't had the need to wash it yet, but it comes with clear instructions on how to do so, and its seems pretty straight forward.
I'll definitely keep using it and recommend to my Pilates and Physio clients.

Caroline Warnes

I'm giving this 4 stars based on my first impressions, as I haven't had the opportunity to use it for long periods. I have a pre-existing spinal condition, so I spend as much of my day standing as possible (most of it at a standing desk) and am probably not the ideal person to fully test a seat cushion over extended sitting sessions.

That being said, from what I've experienced so far, the cushion is comfortable for the short periods of time I spend sitting, and I like that it's lightweight and easy to move between different chairs. I tend to work from a few different spots throughout the day, including at my dining table, so that flexibility has been useful. It's handy that it can adjust comfortable to a range of chairs, and I'm going to try it in the car on my next long trip.

My 10-year-old son has also been using it and seems to enjoy it, which has been an unexpected bonus. The cover appears well made and the cushion has held its shape well with the use it's had so far.

While I can't comment on long-term performance, my initial experience has been positive and I think it would be worth considering for anyone who spends long amounts of time sitting.

Monica

It’s comfortable, easy to adjust, and my lower back feels much more supported during long workdays. Definitely worth it!

Y
Yasaman

Very comfortable and supportive!

The seat cushion is soft and

relieves pressure on my lower back

and hips, while the lumbar support

keeps my spine in a much better

position. It makes sitting for long

periods far more comfortable and

helps me maintain good posture.

I'm really happy with this purchase! Thank you for this wonderful product

Nasim

I have been using the SitComfort cushion for about a week while working from home, and it’s made a noticeable difference. I don’t feel as much pressure on my lower back after long hours at my desk, and it’s much more comfortable than the cushion I was using before. Definitely happy with the purchas.

L
Luiza

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.

D
Daniela

I’ve been using the SitComfort bundle for about a week while working from home, and it’s made a noticeable difference. The seat cushion is supportive without being too firm, and the lumbar support helps me sit more comfortably for longer. It was easy to set up, and the quality feels really good. Happy with the purchase!

J

Comfortable with nice curve for the back bone.

N
Nikkiryan

I spend long hours at my desk, and this seat cushion with the matching lumbar support has made a noticeable difference. The memory foam is supportive yet comfortable, helping relieve pressure on my lower back and hips while encouraging better posture. Both pieces stay securely in place, and the removable covers are a great bonus for easy cleaning. Highly recommend for anyone working from home or sitting for extended periods!

B
Ben

Easy to set up and actually supports your lower back properly. I definitely feel the difference during longer sitting sessions.

J
Jenny

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.
