BERISSA Top Down Bottom Up Cordless Cellular Shades No (Style WS9K)

In this review the BERISSA Top Down Bottom Up Cordless Cellular Shades are evaluated for renters, families with children, and anyone who needs reliable blackout and privacy without drilling. The reviewer found the dual-mode design to be the single biggest reason to buy: it lets sunlight in from the top while keeping the room dark and private below, or fully lowers for total blackout. Installation truly requires minimal tools and the no-drill lateral tension brackets make it easy to fit into many frame types, which is particularly useful for renters and quick window updates.

Key Features

• Dual-Mode Top Down Bottom Up: Allows controlled natural light from the top while maintaining privacy below or full blackout when lowered from the bottom.
• No Drill Installation: Lateral tension brackets anchor without drilling so the shades can be installed on drywall, wood, glass, tile and other surfaces with minimal effort and no damage.
• 100% Blackout Fabric: The honeycomb core blocks light completely for bedrooms and media rooms and helps reduce glare for daytime naps.
• Energy Saving Honeycomb Structure: Cellular pockets trap air to provide insulation that can lower heating and cooling costs compared with standard blinds.
• Cordless Child-Safe Operation: Smooth pull-down action provides easy, safe control and a clean look without dangling cords.
• Removable and Rental-Safe: Brackets can be loosened and removed without residue, making the shades suitable for temporary or rented spaces.

Who It's For

These shades are best for apartment dwellers, parents, and homeowners who want a balance of privacy, light control, and energy savings. The cordless design and no-drill mounting make them a good solution for renters or anyone unwilling to alter window frames permanently.

People who need motorized scheduling, ultra-fine custom sizing beyond the listed dimensions, or a more decorative fabric may want to look elsewhere. Also, rooms that require exact fit for unusually shaped windows might require custom solutions rather than this ready-fit model.
