Which is better for a bedroom?

Both are blackout roller shades. The Joydeco Pro is sold as 100% blackout, so pick it if total light blocking matters most. The DEZ blocks light and adds a heat insulation coating for less money.

Is the Joydeco worth the extra $35?

Only if you need the 75-inch drop or want the 100% blackout claim. At $34.44 versus $69.99 as of November 6, 2026, the DEZ covers the same 42-inch width for about half the price.

Which one is cordless?

The DEZ Furnishings shade is cordless with a free-stop system, so you can set it at any height. The Joydeco Pro listing does not state a cordless feature.

Will either fit a 42-inch window?

Both are 42 inches wide, which usually suits a window with a slightly narrower opening. Measure your window first; roller shades are typically ordered at or just above the opening width.

Neither maker publishes a lifespan. The DEZ uses aluminum alloy rods and a coated finish, which suggests sturdier hardware. The Joydeco gives no material details, so there is no clear durability winner.

Where can I buy each one?

Both are priced new at Amazon as of November 6, 2026. The DEZ is also priced new at a second store, so compare both before buying.
