I sit way too long, probably 10-12 hours a day. I am tied to my computer and often times forget to even get up. I was ready to throw my chair out the window, the second bought since the pandemic began. It is expensive (I am cheap). But I thought why not give it a try. My back and butt hurt and I couldn’t deal with the pain any more. As soon as this arrived I ripped the package and put it on my seat. INSTANT COMFORT!!!! I am now on day 3, my butt no longer hurts…..my back feels better. I will be buying more of these. Just a side note, I did buy another brand too. One for me and one for my 94 year old grandfather. He HATED the cheaper one I bought. I tried it and it was ok…but this is a blessing!!!! Now I have already bought him one 🙂 The company has already sent me an email asking if I had any questions. EXCELLENT CUSTOMER SERVICE……even though I didn’t need it!
