35in x 48in White Cordless Cellular Shades - Top Down Bottom Up

In this review of the 35in x 48in White Cordless Cellular Shades from LazBlinds, the bottom line is simple: these shades are aimed at renters and homeowners who want a quick, no-drill solution for inside-mounted windows with a clean, cordless look. The single biggest reason to buy is the patented No Tools-No Drill system that installs in seconds and avoids permanent changes to the window frame while still offering a top-down/bottom-up design for flexible light control and privacy.

Key Features

• Inside mount only: The shade is made for inside-frame installation and includes a standard 3/8in deduction so the finished blind fits neatly within the window jamb.
• No-drill installation: LazBlinds patented No Tools-No Drill system lets the shade be installed without screws or brackets, ideal for renters and quick installs.
• Cordless operation: The cord-free design creates a tidy window appearance and reduces hazards for children and pets while allowing simple raise and lower control.
• Top-down/bottom-up: The mechanical TDBU stopper enables precise positioning of the middle rail to adjust light and airflow while maintaining privacy.
• Thermal and acoustic benefits: The non-sagging honeycomb cells provide light filtering while helping insulate against heat and cold and softening outside noise.
• Fit range and capacity: The internal spring rod can extend about 1in so the shade fits window widths from roughly 34.7 to 35.6in and supports up to 30kg when mounted as directed.

Who It's For

This shade is best for people who need a tidy, renter-friendly solution for inside-mounted windows and want light filtering plus modest insulation. It fits typical living rooms, bedrooms, and dining areas where privacy and soft light are priorities and the window frame depth meets the minimum requirement.

It is not for anyone needing an outside mount, blackout lining for full darkening in larger rooms, or a custom-width solution outside the stated fit range. Also skip this model if your window jamb is shallower than the minimum 1 1/5in depth required for inside mounting.

Our Verdict
