Omg let me tell you how grateful I am that I found this! I am prone to pain in my tailbone (coccyx) due to prolonged sitting and this most recent time, it wouldn't go away and I couldn't take it anymore!! Now sitting at my desk is much more comfortable and most importantly, pain free! No more tingling nerves either.The reason I gave 4 instead of 5 stars is because I couldn't find the right position on my larger office chair buuuut, I placed it on my smaller one and eureka! As you can see in the picture, the cushion and chair seat are about the same size so maybe that is why, or maybe I just needed a couple of days to get used to it. Whatever the reason, I am not making anymore changes because this is working! I tried it outside the office but again, it wasn't very effective placing it on my sofa but that's okay, this is specifically for the office and once I'm done for the day, I'm almost pain free for the rest of it anyway so... I highly recommend this product!Received in good condition, no smells or tears and on time delivery.Cushion seems of good quality, it pops back up into shape and I'm not short nor am I light so impressive! I will update if anything changes in about a couple of months.
