One piece foam mattress core encasement
View Patent ↗A one piece foam mattress core or innerspring encasement is a single contiguous piece of foam having a mattress core or base and four perimeter side supports and which fits with a mattress core or innerspring to provide an integrated mattress construction. The mattress core or base of the encasement is positioned below the mattress core or innerspring proximate to or against a bottom surface. The mattress core or base and the perimeter side supports are connected along fold lines or grooves in the single piece of foam so that the perimeter side walls can be folded to vertical positions about a perimeter of the mattress core or innerspring. The single piece of foam of the encasement is producible in different sizes to fit with different size mattress cores or innersprings.

a base located beneath the mattress core;
four perimeter supports which are in direct contact with a perimeter of the mattress core;
wherein the base and the four perimeter supports are part of a single contiguous piece of foam, the perimeter supports being folded relative to the base to extend perpendicularly from the base and substantially surround a perimeter of the mattress core.
2. The mattress core foam encasement combination of claim 1 , wherein the mattress core foam encasement is made of polyethylene.
3. The mattress core foam encasement combination of claim 1 , wherein the base of the foam encasement has a plurality of v-shaped grooves.
4. The mattress core foam encasement combination of claim 1 , wherein the foam encasement further comprises a generally V-shaped groove between the base and each of the four perimeter supports.
5. The mattress core form encasement combination of claim 1 , wherein the mattress core is in direct contact with the base.
6. The mattress core foam encasement combination of claim 1 , wherein the density of the foam encasement is in a range of approximately 1.0 to 1.5 lb/ft 3 .
7. The mattress core foam encasement combination of claim 1 , wherein the foam encasement has a total weight in an approximate range of 1.75 lbs, to 3.27 lbs.
8. The mattress core foam encasement combination of claim 1 , wherein a width dimension of the foam encasement is in an approximate range of 50 inches to 86 inches.
9. The mattress core foam encasement combination of claim 1 , wherein a length dimension of the foam encasement is in an approximate range of 87 inches to 97 inches.
10. The mattress core foam encasement combination of claim 1 , wherein a height dimension of the four perimeter supports when oriented perpendicular to the base is in a range of approximately 6.5 inches to 7.5 inches.
11. A one piece mattress core foam encasement comprising:
a substantially rectangular base having a right side, a left side opposite and parallel to the right side, a top side and a bottom side opposite and parallel to the top side, the top and bottom sides being perpendicular to the left and right sides;
a right perimeter support connected to the right side of the base along a fold line;
a left perimeter support connected to the left side of the base along a fold line;
a top perimeter support connected to the top side of the base along a fold line;
a bottom perimeter support connected to the bottom side of the base along a fold line;
wherein the base is placed below a mattress core and the right, left, top and bottom perimeter supports of the foam encasement are folded relative to the base and positioned generally perpendicular to the base and about a perimeter of the mattress core, and
wherein the base and the mattress core have substantially the same length and width measurements.
12. The one piece mattress core foam encasement of claim 11 , wherein the mattress core foam encasement is made of polyethylene.
13. The one-piece mattress core foam encasement of claim 11 , wherein the fold lines between the base and the right, left, top and bottom perimeter supports are in the form of generally V-shaped grooves having an angle of approximately 120 degrees.
14. The one piece mattress core foam encasement of claim 11 , wherein the base and the right and left perimeter supports include a plurality of v-shaped grooves.
15. The one piece mattress core foam encasement of claim 11 , wherein the base is connected to the right, left, top and bottom perimeter supports at connection which have a generally V-shaped configuration.
16. The one piece mattress core foam encasement of claim 11 , wherein the right, left, top and bottom perimeter supports and the mattress core have substantially the same height measurement.
17. A mattress comprising a mattress core and a one piece foam encasement positioned about the mattress core:
the one piece foam encasement having a substantially rectangular base having a right side, a left side opposite and parallel to the right side, a top side and a bottom side opposite and parallel to the top side, the top and bottom sides being perpendicular to the left and right sides;
a right perimeter support connected to the right side of the base along a fold line;
a left perimeter support connected to the left side of the base along a fold line;
a top perimeter support connected to the top side of the base along a fold line;
a bottom perimeter support connected to the bottom side of the base along a fold line;
wherein the base of the one piece foam encasement is positioned proximate to a major surface of the mattress core and the right, left, top and bottom perimeter supports are positioned proximate to respective sides of the mattress core;
and upholstery which fits over the mattress core and the one piece foam encasement.
18. The mattress of claim 17 wherein the right or left perimeter support has a length dimension which is greater than a length dimension of the base, and wherein the top perimeter support or bottom perimeter support has a length dimension which is less than a width dimension of the base.
19. The mattress of claim 17 wherein the right or left perimeter support has a length dimension which is less than a length dimension of the base, and wherein the top perimeter support or bottom perimeter support has a length dimension which is greater than a width dimension of the base.
