Fit

Which encasement size and depth fits your bed

Two numbers decide the fit: the bed size on the label and the depth you measure. The finder below lists the covers for both.

Size and depth

Which encasement fits your bed?

Pick the bed size, then measure the mattress from the bottom seam to the top of the pillow-top.

    Measure the depth

    Stand at a corner, where the mattress is not pressed down, and lay a tape from the bottom seam straight up to the top of the mattress, pillow-top included. That is the depth an encasement is cut for.

    If your mattress measures between two cuts, take the deeper one. A cover that is too shallow strains the zipper, and a strained zipper is the one that splits.

    Read the size on the label

    The tag sewn on the mattress names the size. Full and queen look close by eye, and so do king and California king, but a cover for one will not close on the other.

    Box springs are thinner

    Most box springs are 5 to 9 inches deep. A box spring cover is cut for that depth, while a mattress cover pulled over a box spring hangs loose at every corner.

    Depth is the third number, and it changes from mattress to mattress: measure yours.
