Polyester seat covers?are our basic level products. Polyester fabric weight per square meter for our?high quality?car seat covers is around 75-90g ( we also have 110g or above weight polyester for premium seat covers ), while other competitors will usually use 60-65g polyester instead for a lower quote. The way to make a distinction between good and second?quality seat covers?is very simple, pull the polyester harder by your hands, if it draws back, it's the good quality polyester weighted more than 70g, if it doesn’t come back, it’s the cheaper one. Although cheaper 65g polyester will win some orders due to its lower cost, it will also draw negative feedback from customers who is dissatisfied for the poor quality.
