✔️ Each set includes two tracks—one for each side of your window shade.
I purchased one set, afraid that they wouldn’t work or would look off. Easy to put up and it’s so perfectly dark now. I’m getting another set to finish the job.
Sleepy Time Tracks not only offers a great product, but their customer service is what truly sets them apart. Robert, in particular, went above and beyond to make sure I was completely satisfied with my order. He was incredibly responsive and followed through until everything was perfect. It’s rare these days to find a company that genuinely cares about their customers making sure the product is perfect. Thank you, Robert, for your outstanding service!
The tracks were easy to install and have darkened our baby’s room considerably. No more painter’s tape holding the sides of the shade shut!
