Review: Before I got this one, I tried few other popular lumbar supports on desertcart, nothing worked for me. Other lumbar pillows were all uncomfortable for it was too soft to support my back. This one is amazing, but if you are looking for something that is soft and comfortable, don't get this one. This is very firm and supportive. It feels like it also corrects my posture. I will give it a 5 star!
Review: es un buen cojín ergonómico pero es un poco duro.

## Questions & Answers

**Q: I have severe scoliosis in my lower back. Will this pillow relieve some of the pain?**
A: Hi Jan, thanks for asking! The lumbar pillow is shaped to provide you ample lower back support that helps prop up your lower back, improve your sitting posture, and open up your chest. It should alleviate pressure off of your spine and should help lessen scoliosis pain. Give it a try! I hope this helps, thanks!

**Q: Is it supposed to flatten within 2 days of use?**
A: I have had mine for weeks and use it every day. It has not flattened.

**Q: Hi, can I use an electric hot pad on lowest heat setting on top of this cushion?  Thanks**
A: I don't know why not.  I don't think its going to melt.   I thought it was going to be much softer than it is.  It's very firm....just thought I'd add that.

**Q: Is this safe to use, with its strap, in a car that has seat deployed air bags**
A: I never used mine in the car yet just on my chair.  I think you wouldn't have to use the strap in your car if you didn't want to. Pillow shoul stay in position once your sitting.

*by W***N on November 20, 2025*

The C CUSHION LAB Extra Dense Lumbar Pillow is a total game-changer for anyone who spends long hours sitting. I have tried several lumbar pillows, but none compare to this one's patented, multi-region firm back support. The "Extra Dense" description is accurate; this pillow offers genuine, firm support that doesn't flatten out after a few minutes. It gently yet effectively forces my lower and mid-back into a perfect, ergonomic posture. I noticed an immediate reduction in lower back strain and fatigue by the end of my first day using it. It targets multiple regions of the back, providing comprehensive support rather than just one pressure point. If you suffer from discomfort from long periods of sitting, or if you simply want to invest in better posture and spinal health, this is the product to buy. It’s worth every penny.
