Blinds that go up from the bottom are usually called top-down bottom-up shades: their lower rail can rise while the top can also open downward. The SUNFREE shade is best for buyers seeking blackout and cellular construction; LazBlinds and Shade&Beyond suit renters who want no-drill installation, subject to specific fit requirements. Persilux emphasizes removable tension mounting, while MYshade offers a black blackout option. Check each product’s listed size and installation details before choosing.

SUNFREE Top-Down Bottom-Up Cellular Shades
The SUNFREE shade measures 22 inches wide by 36 inches high and uses a cordless top-down bottom-up design. Its listing describes three opening and closing configurations, allowing the user to adjust light and privacy. The honeycomb construction includes aluminum foil in the fabric and is presented as a blackout, noise-reducing, and insulating option.
Best for: Buyers who want a cellular shade with blackout and seasonal insulation features, along with flexible opening from the top or bottom. Choose this if those features matter more than a no-drill mounting system.
Limitation: The provided product details do not specify a no-drill installation method. Confirm that the shade’s dimensions and mounting requirements suit the window before ordering.
LazBlinds No-Drill Cordless Cellular Shades
This LazBlinds shade is designed for inside mounting and uses a cordless, no-drill system. The listing gives an actual shade size of 26⅝ by 48 inches and a window-width fit range of 26.7 to 27.6 inches. It requires at least 1.2 inches of frame depth. The middle rail can be repositioned to adjust light and air circulation, and a stopper is designed to prevent the bottom rail from lifting the middle rail.
Best for: Renters or homeowners seeking a tool-free installation and top-down bottom-up adjustment. The specific window-width range makes it easier to assess fit before purchase.
Limitation: This is an inside-mount-only product. Avoid it if the window frame does not meet the stated depth or width requirements.
Persilux No-Drill Blackout Cellular Shades
Persilux lists this white shade at 18 inches wide by 36 inches high. Its tension-based mounting is described as requiring no drilling or tools, and the shade can be removed, repositioned, or moved to another location. The cordless, dual-direction design allows light adjustment while maintaining privacy, including the option to block views from both the top and bottom.
Best for: Buyers who want a removable, no-drill shade and a compact listed size. It is a useful choice when avoiding holes or being able to take down the shade is a priority.
Limitation: The listing advises consulting its size chart to select the shade width for the measured window. Check that chart rather than assuming the listed shade width equals the required window width.
MYshade Blackout Cellular Shades
The MYshade shade is listed as 19 inches wide by 36 inches high in black. It has a 1.5-inch cordless honeycomb design and is described as a blackout shade for light control and privacy. The product information also highlights aluminum material and says the fabric is intended to resist flaking, cracking, and fading after sun exposure.
Best for: Buyers who specifically want a black cellular shade with top-down bottom-up operation and blackout-focused light control. Its listed dimensions may suit a narrower window than some of the other options here.
Limitation: The provided details do not explain the mounting method or give a window fit range. Verify installation requirements and sizing before selecting it.
Shade&Beyond No-Drill Cellular Shades
Shade&Beyond offers a no-drill, tension-mounted top-down bottom-up shade for inside mounting. The listed actual shade size is 21⅝ inches wide by 48 inches high. Its spring rod can extend up to one inch, with a stated window-width fit range of 21.7 to 22.6 inches. The listing requires a minimum frame depth of 1.2 inches.
Best for: Buyers who want tool-free mounting and a taller shade, provided their window fits the stated range. Raising the bottom or lowering the top offers two ways to balance daylight and privacy.
Limitation: It is for inside mounting only, and the stated fit range is narrow. Measure the frame carefully and check its depth before choosing it.
Buying Guide: How to Choose Bottom-Up Blinds
What does top-down bottom-up mean?
These shades have movable rails that allow the bottom section to rise and the top section to lower. Raising the lower rail can expose the upper part of a window while keeping the lower area covered. Lowering the top can admit daylight while limiting direct views, depending on the window’s surroundings and shade position.
How should you measure the window?
Start by deciding whether the shade will mount inside the frame. Measure the window at the locations and in the way specified by the product’s instructions, then compare those measurements with the listed shade dimensions and fit range. Do not treat the product’s nominal width, actual shade width, and required window width as interchangeable. LazBlinds and Shade&Beyond provide explicit ranges and minimum frame-depth requirements.
Is no-drill mounting the right choice?
A no-drill tension or spring-rod design can suit people who want to avoid making holes. However, the frame must meet the product’s stated depth and width requirements. Check whether the product is inside-mount-only before buying. If mounting requirements are not provided, as with the listed MYshade details, confirm them with the product information.
Should you choose blackout or light-filtering features?
Choose a shade based on how much light control you need and the product’s stated features. SUNFREE and MYshade are described as blackout options; Persilux is also listed as blackout. Cellular construction is highlighted by several products, but the provided details vary on insulation and other performance claims. Compare the exact product description rather than assuming all shades perform the same way.
