Price and rating as shown on Amazon when we collected them. Both change.

The Palram Canopia Sierra Patio Veranda 3x4.25 is a lean-to garden canopy: a powder-coated aluminium frame carrying clear 6 mm twin-wall polycarbonate roof panels, with two integrated rain gutters running off it. It sits at number four in this guide at £1,179.00, rated 4.6 out of 5 from 198 reviews.

The interesting part is the arithmetic. The title sells a 3 x 4.25 structure, while the Item Dimensions field on the same page reads 4.34 x 2.95 x 3.05 m (L x W x H). The weight is stated twice and the two figures disagree — 66.7 kg under Item Weight, and "60.9 Kg" under a field called Unit Count, which is a count field being used for kilos. The visible star breakdown (80 five-star, 14 four-star, 2 three-star, 4 one-star) totals 100 against the 198 reviews the headline quotes. Every figure on this page is copied from the Amazon listing rather than measured by us; we have not assembled or tested this pergola.

What buyers actually say

Quoted from customer reviews on Amazon

Verified purchase

“If I could give 10 stars I would what a piece of kit, fantastic price, quality is amazing love it, now the real bit, I built this on my own across three (not full) days, very hard work, I used clout nails in the mortar as a line for the bulk head, then used clout nails & washers as a temporary hold for the 1st post, had everything ready to connect THATS THE HELPING HAND BIT there after you can crack on by yourself & build it, seal the bulkhead well, I sealed the rear of the bulkhead & across the top, let both dry over night then went over the top seal again, you will need an impact driver way easier, seal BOTH sides on the center gutter wheel, MAKE SURE YOU HAVE THE GUTTER SECTION THE CORRECT WAY ROUND it has holes that need to line up with the rest, DON'T rush this or you will make mistakes.”

“What an amazing purchase! From the delivery, they kindly offered to carry it through to the garden as it was very heavy, to the quality of the product. The instructions were very clear and easy to use. We are delighted with our new pergola!”
