This product is ideal for those who otherwise can’t buckle up in their Cadillac DeVille, which may include:

    High Quality Seat Belt Extender

    Posted by Nancy Fancy 1960 on 8th May 2018

    Even though my Cadillac is in mint condition going on 19 yrs old, the drivers seat belt was becoming increasingly difficult to pull out of the housing area and buckle into the lap area. I was worried given the age of the car I wouldn’t be able to find someway of replacing the seatbelt. I purchased the adjustable belt to match the cream interior and it works beautifully. Fast shipping and excellent communication as to the shopping status. I highly recommend this product and company.

    Extra Comfort

    Posted by Joe on 18th Aug 2017

    I have almost always been strangled by seat belts rubbing against my neck. A friend recommended that I try a seat belt extension. I ordered an adjustable seat belt extender because I wasn't sure what length I would need. What a difference this extender has made! The seat belt no longer is rubbing against my neck. I have much greater comfort while driving. I highly recommend a seat belt extender to anyone having discomfort from a regular seat belt.
