DOLALIKE Expandable Countertop Shelf, Widens 13 to 23 Inches, Height Adjusts 5.1 to 7.5 Inches, Black

Two dimensions move on this metal shelf rather than one. Width pulls out from 13 inches to 23 inches, and the legs set the deck at anywhere between 5.1 and 7.5 inches, so a run of tall bottles or a stack of pans can dictate the height instead of the other way round. Each shelf carries up to 22 lb, so keep heavier cookware near the legs.

Units stack on top of one another, which is how a single deep cupboard turns into two or three usable levels. Assembly takes four screws and the printed instructions; read them first, as the leg holes decide the height. Cupboards, larder shelves and bathroom worktops all suit it as well as an open kitchen counter.

A note on the listing data: the attribute panel records three shelves and a 9 by 17 by 2 inch size, both of which conflict with the single-shelf pack described in the bullets. The adjustable range quoted above is the more reliable figure.
