Depth Fit Check

Stated inches, added and compared. Pick a mattress, add a topper of the same size if you want one, and every quilted cover of that size is checked against the total. The tool measures nothing; it only works with what the listings print.

Mattress

Topper

Switched off until a mattress is chosen: a topper can only be added to a mattress of its own size.

The rules this check follows

The tool adds stated inches and measures nothing.
The mattress and the topper must state the same size name before any arithmetic; a topper of another size is switched off.
Total = the mattress height the listing states + the topper thickness the listing states. With no topper, the total is the mattress height.
Where a listing leaves the height or the thickness out, no total is calculated and every row reads that there is nothing to check.
Covers listed are the quilted covers that state the same size name as the mattress.
A pocket stated as a range contains the total when the total is at least the shallow figure and at most the deep figure.
A pocket stated as one number is read as its deepest fit: a total at or under it counts as contained, and the row says no shallow limit is stated.
A cover that states no pocket gives nothing to check against.

Every combination this tool allows was run through these rules: 40 combinations, giving 47 rows that contain the total, 0 rows that miss and 64 rows with nothing to check, plus 13 combinations in a size with no cover filed. The miss state is part of the rules and does not come up with the listings in this catalog.

Choose a mattress. The result shows its stated height, the stated thickness of any topper you add, the total, and each quilted cover of the same size with its stated pocket.

Why the sum matters is set out in A topper adds inches to the total, and the difference between range and single-number pockets in Pocket ranges that do not line up.
