Side-tracks for Blackout Shades

Choose the Right Light-Blocking Solution

Sleepy Time Tracks are light gap blockers designed to work with your existing blackout shades and blinds. Choose L-Tracks for simple, effective side-light blocking, Side Channels for maximum side-light control, Top-Tracks to block light above the shade, or Extensions for larger gaps, shallow window openings, certain outside-mount applications, and other non-standard window setups.

Frequently Asked Questions

What are Sleepy Time Tracks, and how do they work?

Sleepy Time Tracks are light-blocking side, top, and bottom that eliminate light gaps along blackout window shades, creating a darker, more restful space—without tools or stress.

What types of products are offered?

There are four main solutions:

  • L-Tracks – versatile fit for most shades, available in removable or permanent versions
  • Channel-Tracks – U-shaped side channels designed for roller shades, featuring adjustable width for a custom fit that seals side gaps and blocks more light.
  • Top-Tracks – Top-Tracks – flexible strips that seal the top edge of roller shades, blocking light leaks where the shade meets the window frame.
  • Extensions – Wider gaps? Shallow frames? Outside mounts? Solved. Sleepy Time Track Extensions are built to handle the trickiest installs, giving you extra reach where standard tracks fall short.

How effective are Sleepy Time Tracks at blocking light?

Sleepy Time Tracks block up to 97% of incoming light by sealing the gaps that standard blackout shades leave behind. The black, light-absorbing interior reduces glare, reflections, and streaks of light—creating a darker room and enhancing your privacy.

Can I trim the tracks to fit my window?

Yes—simply cut them to the desired length using utility scissors or tin snips for a precise fit.

Do I need tools to install Sleepy Time Tracks?

No tools are required. Tracks come with either magnetic strips or high-bond foam tape, making installation quick, easy, and renter-friendly.

How long do Sleepy Time Tracks last?

Sleepy Time Tracks are made to last. The adhesive or magnetic strips stay put, and the durable track material won’t warp or crack with regular use.

What’s your return policy and how fast do you ship?

We offer a 30-day return policy—if you’re not satisfied, just reach out and we’ll make it right. Most orders ship within 1 business day and include tracking for your convenience.
30 Day Money Back Guarantee

Our no-hassle 30 day guarantee removes any risk on your part for trying Sleepy Time Tracks.  If you are not absolutely delighted with your purchase then simply return them for a full-refund. Buyer pays return shipping.
