Best Buy of the Year

After shifting to a work from home situation, my ongoing neck issues became worse. I had the choice to continue seeing my chiropractor every two weeks or change my home chair. After researching chairs like I had at the office, I came across the All 33 and felt like it was going to address the alignment issues I have better than the chair half the price at the home office store. I took a leap of faith and gave it a try and really happy I did. My neck and shoulder pain has been alleviated and I can sit through 2 hour conference calls now. I should add that my team wants to know when they're going to get one now, and I'm not sure I'll be able to head back to the office without it! Thank you for a wonderfully designed product with the user in mind.

My Long Search is Over

I have taken some time to really get a feel for my All33 Backstrong C1 Vegan Leather chair. First it took more time to open the box then to put together :D. Less than the 10 minutes quoted, and I was sitting in my new chair. I Co-Own a business that requires a lot of desk time. I have worked from home for the past 3 years. I have significant arthritis in my lower back, neck and suspect mid back as well. I have fibromyalgia. I cannot stand for too long as I also have plantar fasciitis. This causes a lot of pain in my feet. In October of 2019 I started researching and finally, in December of 2019, purchasing an electric lifting desk. The whole desk lifts so that I can stand and/or sit. I did find some relief from the back pain with the desk in the standing position. Since I cannot stand all the time, this led me to looking into and purchasing many different chairs. All of which I have either given away and/or are placed around my home. Eventually I ordered this chair. I was not sure at first, as the seat cushion is a little firm to start, but I have found that it does soften up, somewhat, over time. I also started making adjustments to the tension, as needed. The adjustments were small so that I could find just the right fit. I have been using this chair for over a month and have since purchased another All33 Backstrong C1 chair, only this time I got the color I really wanted Red and Black (the first one was all black still very nice) I just wanted to add color to my office. I gave the other chair to my business partner after she tried for a couple of hours and said, "my back has been hurting all week and after 2 hours in your chair the pain is gone". She is a Dr and sits all day to see her clients via Telehealth. She has a genuinely nice chair, but it does not have the support this one does. She is currently alternating between chairs and is feeling great. She has spinal stenosis and finds the alternating highly effective at helping her posture and pain. I am now in the position of having to soften the cushion on this chair, as I have only had the Red and black one for about a week, and it does take some time to soften the seat. I am no longer shopping for furniture that will reduce my pain. I have found what works, this chair, my standing desk with a standing pad and alternating between standing and sitting. I am grateful to have found this combination as without them I am afraid I would soon be filing for disability. I no longer even entertain that idea. Thank you for your dedication to quality and care of people enough to continue with you pursuit of making "a chair that is Just Right".
