"Great work. Very professional,looks like it was factory installed. Absolutely great craftsmanship. I highly recommend them to anyone looking for a new interior on their vehicle. You will LOVE it."
Eliseo did a great job on installing my Katzkin custom leather upholstery! I love how it turned out and would highly recommend him!🧡
I can not express enough with words what a pleasure it was to work with this company and my local installer (EM Upholstery Technology; Eliseo)! Outstanding service, from start to finish. And my local installer, holy cow, he was the epitome of a professional, a true expert at his craft! I am continuing to do business with this company and of course the installer, Eliseo! I would definitely recommend friends and family!
Eliseo is absolutely amazing, so easy to work with, super informative and such quality work. They are definitely the best at what they do. I’ll be returning to him again
I had Katzkin leather installed in my 21' F150, and I'm very satisfied with the results. Eliseo got it done much faster than anticipated. I would definitely get more upholstery work done here.
This is the second vehicle I have taken to Eliseo. After the first time I was not even worried about the outcome the second time! I highly recommend EM Upholstery. I even moved further away and made sure that I still went to Eliseo. He finishes in one day, he communicates and he treats your vehicle as if it were his own. I came to pick up my truck and he had even cleaned the whole inside of my truck. I will always go back when I need leather!
