Cordless Cellular Shades 29 in x 64 in Beige TDBU - Blackout

Our review of these cordless cellular shades finds them ideal for renters and families who want a clean, dark bedroom without tools or drilling. The LazBlinds top down bottom up (TDBU) design and true blackout silver-plated cell liner deliver room-darkening performance while the cordless system keeps cords out of reach of children and pets. Installation is unusually simple because the product is designed for inside mount only and uses a patented No Tools-No Drill spring rod that presses into the frame, so the biggest reason to buy is fast, damage-free fitting in appropriately deep window frames.

Key Features

• No Tools-No Drill system: The patented spring rod installs without screws or brackets, so renters can fit the shade in about 30 seconds without damaging the window frame.
• Top down bottom up operation: The TDBU mechanism lets you lower the top and raise the bottom independently to control privacy and light at the same time.
• Real blackout cells: A silver-plated layer inside each honeycomb cell blocks sunlight and UV rays for daytime sleeping and better light control.
• Cordless safety: The cord-free design provides a tidy window appearance and reduces entanglement risk for children and pets.
• Thermal insulation: Non-sagging honeycomb structure traps air to reduce heat transfer, helping keep rooms cooler in summer and warmer in winter.
• Precision fit for inside mount: The shade is made slightly narrower than the ordered width to allow a snug inside mount fit; the spring rod extends about 1 in to secure in frames 28.7 to 29.6 in wide.

Who It's For

These shades are a strong fit for renters, landlords, and homeowners who need a blackout solution without drilling holes. They are especially useful in bedrooms or nurseries where complete darkness and cordless safety are priorities, and for anyone who prefers a neat, fabric-covered window that also provides thermal benefit.

They are not suited for windows with less than 1 1/5 in of frame depth or for outside mount installations, since this model is designed for inside mount only. Buyers who need a wider size, outside mounting hardware, or continuous cord control should look at alternate products.

Pros & Cons

Pros

• Quick, tool-free installation that avoids drilling or permanent changes to the frame.
• Effective blackout performance thanks to the silver-plated inner layer.
• Clean cordless appearance and safer for homes with children or pets.
• Thermal and noise reduction properties from the honeycomb construction.

Cons

• Inside mount only with a minimum frame depth requirement, so not usable on all windows.
