A pocket with a deep end only: stated by 4 listings, left out by 7 listings. Part: The quilted cover.

Must contain

A total has to sit inside the pocket of the cover that goes over it, and covers of the same size do not promise the same window.

Every listing that states it

11 rows, grouped by the part each listing is filed under.

Five cover listings state 8 to 21 in. The other six state five different figures: 20 in as one number (2 listings), 16 in as one number, 18 in as one number, 8 to 16 in and 8 to 20 in.

Some of those are ranges and some are a single number. A range prints both ends; a single number prints a deep end only, and this site does not invent a shallow end for it.

Read together, every stated pocket here contains a total from 8 to 16 in. Past 16 in the listings part ways, and a total can sit inside the pocket of a cover and outside the pocket of another cover of the same size.

A listing filed with the toppers also states a pocket, 6 to 18 in, on BEDLORE Queen Mattress Topper, Thick Pillow Top. It is counted on the topper side of the catalog and left out of the figures above.

What goes wrong

Treating the range of a single cover as if it were every cover’s. Listings of the same size can give different deep ends, so a total near the top of one range can land outside another.

What the listings do not say

The single-number listings do not say whether their figure is a maximum, a typical fit or something else. This site reads it as the deepest fit and prints that reading on every row where it is used.

Check it with a tool

Stated heights, thicknesses and pockets are added and compared in the Depth Fit Check.
