## Customer Reviews

### ⭐⭐⭐⭐⭐ Another cushion purchase from Ergo21
*by J***M on August 15, 2016*

The following is an e-mail I sent to the owner of the Ergo21, Steve Gambhir, on 08/05/16. This is my second cushion purchase from Ergo21.Steve:Thanks for reaching out to me. I don't know if you remember me from just over a year ago. I had ordered the original cushion (1.5" front to back) as well as the 2.0" Sport version. The Sport version was a bit to bulky and sat me too high in my car. Plus it was uncomfortable under my thighs because of the thickness. You and I spoke by phone and then I returned the Sport version to you.As you might recall, I had lost 100 pounds and, after buying a new car in November of 2014, I began experiencing severe buttock pain. I bought and returned more than a dozen seat cushions and, since I couldn't find one that relieved the pain while driving, I just gave the car to my wife. She ended up keeping the car but, whenever I drive it, I use your original seat cushion. For the most part, it does a good job of relieving the pain though not always. It really depends on how I am sitting in the seat. Since it is not my normal car, I have to adjust the seat until I can find the right position for the cushion.Fast forward to now. The old clunker that I am driving is finally on its last legs. I was hoping to find a new car with a seat good enough that I would not need a cushion at all. I have looked at over 15 cars but no such luck. But now I am going to have to pick something whether it has a good seat or not since I cannot walk everywhere I go. Plus I drive over 80 miles round trip to work every day (2 hours round trip).In the last few weeks I have found out what my problem actually is. It seems I have a problem with my Ischial Tuberosity. You probably know what that is but I only learned recently that they are the two "sit" bones on your pelvis. This is where the hamstring and other muscles are attached. Apparently, there is a bursa in between the bone and the attached muscles. The pain is created when that bursa becomes inflamed and pressure is applied directly to it from sitting on something hard. The pain can also be created from the hamstring being torn just below the bursa site. It really is quite painful, burning at the site and throughout the buttock region. It has been hurting much more lately as well because I have been test driving all of these cars without using the cushion, hoping to find a seat I could use without the cushion.To make matters worse, we are going on vacation in a couple of weeks. I live about 25-30 miles north of Baltimore and we are driving down to Myrtle Beach, SC. The trip is over 500 miles and will take us about 10 hours. So I will certainly take my original cushion with me. But, because I have never traveled that long or far using the original cushion, I wanted to get your latest version to see if that makes a difference. Plus I will try it as I continue looking for a new car. Now that I know I will not be able to find a car with a comfortable seat, I will try both of your products as I continue my search.Since the original cushion was 1.5" front to back, I notice that your newest version has increased by a half inch in the back and decreased by a half an inch in the front. I assume the thinking was to provide more cushioning in the back and less pressure under the thighs in the front since it slopes down under the thighs. Hopefully, the newest version will be even better than the original one. I am keeping my fingers crossed. In addition, if it turns out that the original 1.5" works better for me, I was wondering if you have any of those still available. It is always helpful to have more than one so you don't have to carry it in and out of the house and, of course, having an extra one is always good in case your main one becomes damaged or lost.So on this order we'll go with the newest version (2" down to 1"). If this works for me I'll probably get one more of the newest version and, if available, I'll probably get one more of the original 1.5" version, too. I should know what works one way or the other when we get back from vacation. In the meantime, thanks so much for your help and for taking an interest in your customers. I can tell from the reviews that your customers are surprised but pleased that you do all you can to help them out. Your sincerity is also evident in the video I saw of you and that woman who was interviewing you.And, incidentally, I have it shipped to my office because there is no sales tax in Delaware and there is always someone here during the day. Whereas, when things are shipped to my home, packages are left unattended outside all day. I'll be looking for this sometime next week. Again, thanks for your help and I certainly hope you have a nice weekend. And as I said before when we first spoke, I am so glad you were able to come to the United States and realize the American dream. With all of the hate and fear mongering throughout the country, we really are good people and this is an excellent place to live. Talk to you later.

### ⭐⭐⭐⭐⭐ Really effective, high quality, thoughtful design.
*by J***H on May 21, 2023*

A friend of mine who'd been in the car business for a long time once told me that the average car seat is designed to be most comfortable for seven minutes, since that is the average amount of time a new car buyer sits in the seat of a car they are considering purchasing. No wonder then that many of us become bewildered when way sooner than we expect we have the feeling, then the certainty that our car seat has given out and is no longer comfortable and does not support us.The Ergo21 cushion is a very legitimate and thoughtful design that addresses this issue in a very sophisticated and effective way. A combination of very high grade foam and a fantastic technology of liquid cell suspension it supports and cushions all at the same time. During the winter I am often driving three hours at a time one way then making the return trip a day later. If your seat is not comfortable for three hours you know it. The Ergo21 original cushion made my rides an absolute pleasure. The cushioning and support is absolutely superior. Then. add the fact that the two inch cushion has a gentle taper that levels out the height of your bottom and knees created by most car seats and certainly by bucket seats. When your bottom is below your knees it can create back and posture issues that are exacerbated the longer you drive in that position. The Ergo21 addressed all the issues I was concerned with at a level of quality and efficacy I had not even imagined. Add to that the incredible responsiveness of the company and the owner and designer Steve Gambhir and you have a very high quality and effective product with amazing customer support. I was so curious as to the liquid cell technology and overall effectiveness and quality of the product that I called and Steve was only too happy to delve in to the technology as well as the application and effectiveness of all the Ergo21 products. This is a unicorn people, a very high quality product thoughtfully designed and old fashioned customer service at the very highest level.

### ⭐⭐⭐⭐ Effective Product
*by B***O on March 19, 2015*

Purchased the Ergo21 due to the drivers seat in my 2011 BMW X5 breaking down. Drives of more than 10-15 minutes were not kind to my upper legs and rear end. This cushion makes a significant difference in comfort and backs up the claims made. So, why 4 stars instead of 5? The width of the cushion should ideally be about 2 inches wider. I find it challenging to position the cushion perfectly so that I'm not hanging over one side or the other, as it is smaller than the actual seat that I am sitting in. That aside, this is an effective cushion that makes a significant difference in comfort, especially on longer drives.
