  • I work night shifts at the hospital and sleeping during the day was a nightmare. Tried everything — eye masks, regular curtains, nothing worked. Installed Blackly in literally 5 minutes and my room went completely dark. I'm finally getting real sleep before my shifts. This thing is no joke."

    Sarah Mitchell

  • Our newborn was waking up every time the sun hit the nursery window. My wife found Blackly at 2am and we had it up by morning. No more early wake-ups, no drilling holes in the walls. Wish we had found this 3 months ago honestly.

    James Reynolds

  • Living in NYC with a street lamp directly outside my window was destroying my sleep. Landlord won't let me drill anything so curtains were never an option. Blackly solved both problems. Room is pitch black now and no damage to the walls. Worth every penny.

    Nicole Williams

    How Does It Work?

    • step 1

      Measure your window and mark where the blackout panel needs to be cut. Leave a small extra margin around the edges to ensure complete light blocking.

    • Step 2

      Trim the blackout panel to size using the included cutter, ensuring a clean and precise fit.

    • Step 3

      Peel off the adhesive backing and attach the Velcro and magnetic strips to the window frame. Repeat the same process on the blackout panel to ensure a tight, light-blocking seal.

    • Step 4

      Secure the blackout panel in place by attaching it to the Velcro and magnetic strips, ensuring a firm seal around the edges.

    • Blackout Complete

      Your room is now fully dark — ready for deeper, uninterrupted sleep.

        FREQUENTLY ASKED QUESTIONS

        contact_support

        ❓ Does it really block 100% of the light?

        No "mostly dark," no "pretty dark" — we mean pitch black. BLACKLY's high-density fabric with reflective silver backing eliminates every trace of light, including sunrise, street lamps, and car headlights. When it's installed correctly, your room goes completely dark. That's the whole point.

        Zero risk. BLACKLY uses adhesive Velcro that removes completely clean — no holes, no marks, no damage. We've had customers in NYC apartments use it for over a year and remove it without a trace.

        Order a size larger than your window — that's the rule. You can always cut more, but you can't add material back. If you're unsure.

        That's exactly who we built this for. Once installed, your room becomes pitch black regardless of what time it is outside. Sunrise, noon sun, whatever — your room stays dark until you decide otherwise.

        As long as your window has a frame to attach the Velcro strips to, yes. BLACKLY has been installed on arched windows, angled windows, and even skylights. If you have a unique window shape, reach out before ordering and we'll help.
