I love the seat part. I recently took a job where I sit more. I have had back surgery and have rods, screws, wires and who knows what else in my lower back and sitting for prolonged periods or time is painful. This cushion helps with support, taking pressure off my tailbone, and keeping my hips in alignment so when I stand up I'm not so stiff. The back piece is great when I want to put it on to lean back and stretch out those upper back muscles. However it pushes me too far out in the chair and I feel like it's going to make me fall of my seat. I've tried it on 3 different chairs and it didn't work on any of them. But would 100% recommend the seat. All my coworkers steal my seat when I'm away from my desk.You need to know why you have back pain. Is it poor posture that leads to back pain, or back pain that leads to poor posture that leads to more back pain? I doubled my core workouts, with emphasis on my back, and that has helped. The cushion is very comfortable and only helps to remind me to sit properly, which I do for a good 6-7 hours a day. BIGGEST TIP: Pay particular attention to the width of ANY cushion, as your butt might be wider! The fact that it doesn't cover my chair seat is OK, because I've discovered that I lounge in my chair like a cat instead of sitting properly. I do wish that the seat had elastic straps like the lumbar support, though, to keep the seat from sliding around (which is because of my bad sitting habits).My mom is an older heavy lady who has dislocated disk in her back and arthritis on her spine. She has a hard time seating down that hadn’t flown in a while so this was worth a shot purchase.I got it for her and tried it on a short 30 minute car ride.She lives out in the country so she would always want me to drive 5 miles and hour for the bumps or she screamed of pain. With this chair cushion not one single slow down! So tried it on a 2 and half hour drive no stops for her to rest! Finally got her to fly out on a 4 hour flight and she is taking her chair Cushing everywhere. This chair cushion has definitely helped me bring my mom relieve and back out exploring different countries. Definitely recommend and for its price omg don’t mind buying several to keep in my car, her car and for my brother when he picks her up.This is a 2 peace set. I bought it for my side by side. I am only 5ft and need the extra boost so I could see out the windows. This has helped. The support is great, much better than the pillows I was using.I got this for work. Our chairs are painful to sit in for 10 hours. This cushion and back support has helped tremendously!I initially attempted to use both the back and hipcushions in my car, but neither cushions were very forgiving. The back cushion extends me out and doesn’t over any give when I lean against it. The hip cushion seats me up very high and doesn’t offer any give as well. I need the support in both areas which is why I rated it as high as I did.I have a slipped disk in my back that is painful when I sit. The seat cushion is excellent. I went on a 12-hour road trip and to my surprise I could walk when I got out of the car. I didn't think the cushion would be that helpful, it was and continues to be required for me when I get in the car!! Buy it!!After trying different office chairs I tried this seat and back combo and it has alleviated all my hip pain. I even have it on a hard metal chair and you wouldn’t know it. Is firm enough for support but have give still. Great deal.Was having back problems due to sitting on dining room chair working at home in lockdown. Happy with product and lower back much better. Couple,of issues 1) for the back pillow the straps are not tight enough and the back cushion falls down I’m going to use some cable ties to keep it where it should be. 2) the bottom cushion slips forward off the seat of the chair I’m using so when that happens the back cushion falls down and out of place - see pictures. Solution is to keep readjusting. Hope this is helpful.I hurt my back last week. To the point I could hardly walk..I'm a bus driver so the position that I sit in for hours on end, the seat itself, gear changing and braking made the rest of the day unbearable. My friend suggested a lumbar support cushion so I shuffled off home, went online, compared a few and ordered this little beauty!!Excellent delivery time.. It was ordered Thursday evening and delivered Saturday morning!!In my opinion it is So comfy, very supportive.. I feel like it's hugging me and provides extra padding round my tender back and seems to absorb the bumps in the road before they reach me..Obviously I'm not 100% pain free but would say this cushion helps massively.I believe it has truly saved me from having to take time off work..!Thank you xI have Fibromyalgia and Arthritis and spend quite some time on a computer, although I have a new computer chair I was still in pain with my lower back in particular. Having got my back support and cushion today I am very pleased with your product, I sit better, my spine is more supported and its helping with my pain levels. I have also invested in a foam foot cushion to raise my legs a little under my desk to help as well. All in all its a very good product. I didn't read the instructions and wondered why the cushion looked so flat lol but its plumped out nicely after reading that I needed to let it air for five to twelve hours. All is well. thank you. So keep the good work up! Deborah.I got this after a lower back injury (herniated disc L5 S1) in hopes it would give me some more support.After figuring out which way around it went, with the lumbar cutout at the back, I definitely felt it was helping keep pressure and compression away from my lower back. Also the backrest was so supportive, yet flexible, and really helped.It's a premium feeling product - I've had it for 6 months now, and it feels as new as the day it arrived. No sunken areas, no loss of shape. It's also quite grippy and easy to personalise and stay in a comfortable position with.It has definitely improved my day to day comfort and posture when working from home for 8 hours a day.My wife likes to come and sit in it from time to time as well, and she says it's so comfortable when she does.I have been amazed by this product! Delivery was extremely quick (less than 24 hours!) in spite of opting for free delivery and arrived well vacuum-packed and boxed. I left overnight before using.The first time I tried the cushion and back support, I was a little disappointed, although it was extremely comfortable. I used on the sofa at home (back support seemed to work fine with using straps) and on my office chair. Over the course of the next few days, I was really surprised by the amount of relief and support given to my painful lower back and hips. A week later my hips are now almost pain-free for the first time in ages, whilst my back is responding more slowly, but is definitely more comfortable and less stiff. In fact, I am considering buying another set for work to save me carrying them backwards and forwards! Thank you so much for such a good product that really works!
