Overview
A universal replacement canopy from Alion Home sized 20 feet by 10 feet in a muddy water tone, meant to slide over an existing wood or metal pergola frame in place of a worn-out cover.
This is a cover only: the pergola frame and the weighted rods that slide into its rod pockets are both sold separately. The listing is explicit that the PU-coated side must face outward toward the sky for the waterproofing to work, and notes some buyers have installed it backward. Custom sizes are available direct from the maker in California.
- 20 ft by 10 ft cover size
- UV and rain resistant polyester fabric
- Corner tie-down and rod pocket system

What buyers say
From Amazon customer reviews.
Buyers consistently like the fabric's thickness and color and say it blocks sun well, with several calling it truly waterproof when installed correctly. The recurring complaint is water pooling on top in heavy rain, which several reviewers say eventually seeps through despite the coating, and one buyer's corner tie-down stitching failed in roughly 20 mph gusts.

Questions about the Alion Home pergolas
Common buyer questions answered straight from the product spec data - no fluff, no "it depends".
Is the Alion Home pergola cover fully waterproof?
The fabric is coated to repel rain, but several buyers report it is more water resistant than fully waterproof once water pools on top rather than running off.
Does the Alion Home pergola cover include the rods or frame?
No, the frame and the weighted rods that slide into the rod pockets are both sold separately.
Which side of the Alion Home cover should face up?
The PU-coated side must face outward toward the sky for proper waterproofing; installing it backward is a reported mistake.
