FAQs

Please read our FAQs page to find out more.

Who is the CabSupport M2 designed for?

The M2 is designed for anyone who sits for long periods and cares about spinal health. It’s ideal for office workers, students, long-distance drivers, teachers, professional gamers, artists, or anyone experiencing lower back fatigue. Whether you're working, studying, meditating, or creating, the M2 helps support proper posture and reduce lumbar pressure.

Why might I feel a little uncomfortable at first?

Mild discomfort can happen during the first few uses because many people develop subtle posture shifts from prolonged sitting. The M2 is ergonomically designed to guide your spine and pelvis back into better alignment, which may take time to adjust to. There’s no need to force it—use it gradually, starting with short periods and increasing as your body adapts.

What’s the difference between CabSupport M1, M2, and M3? Which one should I choose?

Each model in the CabSupport SpineSeat™ series is designed with unique features to meet different needs:

  • M1 – Built with high-density memory foam and an aerospace-grade plastic base, the M1 focuses on posture correction and tailbone pressure relief. Its larger size makes it ideal for larger body types or male users. Firm yet comfortable, it supports proper spine alignment, whether you’re at a desk, in a library, study room, or even driving.
  • M2 – Features a two-piece, breathable gel structure that distributes weight evenly, relieves tailbone pressure, and adapts to your movement. The soft, waterproof, and antibacterial gel makes it perfect for women and children. Lightweight and flexible, it’s suitable for long sitting hours at home, in classrooms, coffee shops, or in the car.
  • M3 – Designed with dynamic adjustable lumbar support, the M3 adapts to your body’s natural movement, providing ergonomic comfort without rigid correction. Best for users seeking all-day back support and relaxation at home or in the office. (Note: not recommended for driving use.)

👉 In short:

  • Choose M1 if posture correction, spine alignment, and larger body support are your top priorities, including in-car use.
  • Choose M2 if you want soft, breathable, tailbone-relieving comfort in multiple environments, suitable for women and children, including in-car use.
  • Choose M3 if you prefer adaptive lumbar support for long-term comfort at home or in the office.

Really helps with my posture and pain relief

I really like this product. It’s easy to handle and I can use it while working or I can take it to the car if I have a long drive. It feels good on my back and helps with pain relief. I also notice I sit better, and my posture improves

It changed my life

I’m completely serious when I say that it changed my life. I work a lot from home, sitting down all the time. I have problems sitting straight and nicely, even though I should with my herniated disc. This seat has changed it all.
It forces you lightly to sit straight and aline your spine nicely. The whole chair is firm, but it bends a little to fit into your body better. No adjustments, no knobs, just pure comfort anywhere you want.
I can honestly say that after using it for just an hour my pain started to go away. After two weeks of using it all the time, I can feel an improvement in my spine and decrease in pain.
It’s very light, so easy to place it wherever you want and take with you to another room.

This is AMAZING for my back and posture! I am SO grateful!

I work at my desk(s) usually 'perched' on the edge of a sofa or bed. And my back (and I) get so SO weary. As I sit there, I kind of look -- and feel -- like a badly curved C shape. I wish I could explain more fully just how AMAZING this feels for my back... I'm actually sitting upright and comfortably. And I can kind of 'rock' for a gentle back massage. My husband is trying to take it from me. But nope. It's mine all mine. Though it looks like I'll have to order one for him now! Thank you so much for an incredible back saver!

LADONNA BAILEY

A little awkward to sit in but i guess it’s something to get used to.

Hi Ladonna,

Thank you so much for sharing your honest feedback 💛

Because the SpineSeat M2 is designed to help guide the body into a more upright and supportive sitting posture, it can feel a little unfamiliar or awkward at first — especially if your body is used to a different sitting habit.

For many users, this feeling gradually improves with time as the body adjusts. We also usually recommend starting with shorter sitting sessions in the beginning and slowly increasing usage time instead of using it for long periods right away.

We truly hope it becomes more comfortable and supportive for you over time, and if you ever have any questions, please always feel free to reach out to us again.

Warmly,
Chloe

 That’s a great

I’ve been using the seat cushion for a few weeks now, and it’s made a noticeable difference in my comfort during long drives. The cushion is firm yet supportive, with just the right amount of softness to relieve pressure on my lower back and tailbone. The design fits perfectly in my car seat and doesn’t slip around while driving. The breathable cover also helps keep it cool, even on warm days. Whether you’re commuting daily or going on a road trip, this cushion adds an extra level of comfort. Highly recommended!

Ergonomic Lumbar Support

I like this more than I thought I would. I''ve been using this when I feel like sitting on the floor. It''s nice being able to have something to lean back on and feels wonderful on my back. The padding is much more comfortable than the floor as well, so I''m able to stay there for a much longer time period. (This makes my cat happy as well when she inevitably ends up in my lap.)

The cushions are a nice and welcome change to sitting out on a step. The back is nice and supportive, you won''t flip over unless you really try. Construction is good and professional.

Size Didn’t Fit My Setup

I found the lumbar support cushion to be a bit too large for my chair and personal seating space. It didn’t quite match my setup, so I wasn’t able to use it as intended.

Great product

Great product! I do feel a difference after sitting on this to play with my toddlers vs sitting on the floor. My back doesn’t hurt as much like before. Recommend!

Great for my back, but not quite wide enough for long time comfort.

Hi Elizabeth,

Thank you so much for taking the time to share your feedback with us 💛

We’re really happy to hear that the M2 has been helping your back, though we’re also truly sorry to hear the width hasn’t felt quite comfortable enough for longer sitting sessions.

Your feedback is genuinely valuable to us because comfort can feel very different from person to person, and comments like yours help us continue improving future designs and sizing considerations.

Thank you again for your honesty and support, and if you ever have any questions or need anything at all, please always feel free to reach out to us.

Warmly,
Chloe

Gradual Adjustment

I have a herniated disc and had high hopes for this chair as it seemed like exactly what I was looking for. At first, it felt a bit uncomfortable, but I gradually adjusted to it over time. Now I can sit for long periods without pain, and it really supports my back well. I’m very happy with this chair after giving it some time to get used to.

 Perfect for uncomfortable dorm chairs

'I’m a college student living in a dorm, and the chair they provided sucks, it’s hard on my back and when I study for a long time it really makes my back hurt.

I got this on a whim and it really saved my back honestly. I had this for a few weeks now and it made this dorm chair so much more comfortable. The back strap is sturdy and easy to attach this on to any chair. The memory foam is firm enough to keep my spine upright, but not so hard that it feels like I’m leaning on a brick.

I highly recommend for college students that study for a long period of time.'

Really comfortable

'Always kind of wanted one of these and this is just really nice quality. Being able to just sit wherever you want is nice and then to have good posture as well. I also got a computer chair that works well with it and improves the feel overall.

It flexes with your body just enough. You don't feel like you are going to fall over but it isn't digging into you either. The padding is nice and soft and can sit in it for a while. Overall It is really comfortable and promotes good posture, great product.'

Dorm chair survivor here!

Dorm chair survivor here! This chair cushion turned my cement-hard desk chair into a study throne. Pull all-nighters for finals? The arch pushes my slouching spine upright like a strict librarian。Roommate tried to claim it as ‘community property’. Nope. Get your own!

 Excellent lower back support

'One of the benefits from transitioning from working in the office to working from home has been my back pain, or more precisely, relief from it. For 20 years I had been using the same crappy chair assigned to me when our building opened and, after many years of 10+ hour days, I found myself slouching so much to just provide some relief to my back. Since most of my co-workers were in other countries, my life was dialing in to one call after another rather than walking from meeting to meeting, so my chair needed to go.
Working from home allowed me to set up a space with a real ergonomic chair which, for the first few years felt great but over time also began to lose it's comfort and my lower back began hurting again. I've used various cushions, which were nice but did little for the back support I felt I was missing. This simple device works amazingly well. In addition to providing some nice padding, it provides amazing support to my lower back in just the right places. Since my workspace can be rather warm in summer, I like how it's designed with ventilation in mind.'

Helps quite a bit!!

'I honestly didn’t expect this ergonomic back support to make such a noticeable difference, but it really has! I spend long hours working at my desk, and by the end of the day, I used to have so much tension and pain in my lower back. Since I started using this lumbar support, that discomfort has significantly decreased. It fits perfectly on my office chair and stays in place — no slipping or constant adjusting. The padding is firm enough to give great support, but still comfortable enough for all-day use.

I also appreciate how breathable the mesh material is — it doesn’t make my back hot or sweaty like some other ones I’ve tried in the past. It honestly feels like my posture is naturally improving just from using this consistently. If you sit for long periods, especially at a computer, I highly recommend giving this a try. It’s such a simple upgrade that makes a huge impact.'

 Works well, even for bigger people.

Sitting on this now! I am 5'7-5'8 153 and this works great. My husband who is 230 and 6'4 likes it too (he only used it once because thats all he could get before i took it back)... the price is much more reasonable than the $80 one I always see!

Supportive

This “cushion” is primarily made of rigid plastic with a thin cushion layer where it meets your back and butt. It’s comfortable enough and provides decent support, and the rigidity reminds me not to slump when sitting for long periods of time, which has helped with some back pain. I’ve been using it for two weeks now and even though it took some time for me to decide if I really liked it or not, I do think it is helping my posture. I also like that it’s portable and I can move it to another chair anytime I want. My butt is curvier than anything I see in the product listing so I had some doubts about the fit. I did have to try a few times to find a position that resulted in the promised support, and now I like it and use it every day.

This definitely helps

I was about a week into pretty severe lower back pain, when I decided to start experimenting with various contraptions to try and prevent this from happening again anytime soon. I sit at a desk all day in a chair that’s not the greatest. I started out with one of those foam pillows that has the cutout where your tailbone would be (to supposedly relieve pressure). It did absolutely nothing for me, and would be better advertised as a hemerrhoid pillow lol. Then I got this and immediately felt like it was actually supporting me and gently forcing my body into a better position. I’ve been using it for 4 days now and plan on continuing. Definitely helps a lot.

sturdy

I'm hoping my CabeVibe back support will meet my expectations; and it looks as though by the insert information there will be more uses - beach? office? yoga sitting meditation? how great. It is very sturdy with the nice soft cushions that attach easily to provide more comfort. My only caution would be that sitting in this very supported position for long periods - may cause some discomfort. So; with this I would advise to use the chair support for short periods until you are used to it - and of course as time goes on it will be more comfortable. Like a new pair of shoes it needs a little breaking in period.
