ensures that the padding or packing 22 therewithin is
also prevented from displacement. The fastening of the
internally packed sheaths 20 ’to the core assembly by the
fasteners 48 is thought to be of particular importance in
securely tying the several elements together. The con

of the invention shown, it should be borne in mind that
the sidewall assembly has a height approximating the
height of the spring units of the core, so that in each case
the connections 26 of the tubular sheath to the sidewall
are spaced intermediate the planes of the upper and lower
of the mattress, such stress being distributed oppositely
from the point of application lengthwise along the sheath
and ultimately being transmitted to a substantial number
of the springs of the core.

larger in length and width than the length and width of
