BERISSA Top Down Bottom Up Cordless Cellular Shades No (Style ZZRW)

In this review of the BERISSA Top Down Bottom Up Cordless Cellular Shades, the bottom line is simple: these shades suit anyone who wants true blackout, flexible light control and a rental-safe no-drill install. The reviewer found the dual-mode top down/bottom up design especially useful for letting daylight in from the top while keeping privacy below, and the cordless, tension-bracket mount makes fitting to window frames quick and nondestructive. Installation notes and real-world performance on light blocking, insulation and noise reduction are covered below.

Key Features

• Dual-mode design: The top down bottom up function lets users admit natural light from the top while preserving privacy at the bottom in one simple motion.
• 100% blackout core: The honeycomb fabric blocks light completely when fully lowered, making it suitable for bedrooms and media rooms that require darkness.
• No-drill tension system: Dual-tension lateral brackets anchor to frames without drilling, enabling fast installation and clean removal for rentals or retrofits.
• Insulating honeycomb: The cellular structure forms air pockets that improve thermal performance, helping reduce heating and cooling load.
• Cordless safety and ease: Smooth cordless operation is child-safe and provides straightforward height adjustment without tangles.
• Sound dampening: The honeycomb channels also absorb noise, offering a quieter indoor environment.

Who It's For

This product is ideal for renters, families with children, and homeowners who want blackout performance without altering their window frames. The quick 1-3 minute self-install process and removable brackets make it a practical choice when drilling is not allowed or desired.

Those who need exact custom machining, motorized controls, or specialty decorative trims should look elsewhere, since this cordless, no-drill system focuses on functionality, insulation and privacy rather than custom automation or ornate hardware.
