Cushion covers, cushions, and methods of using the same

1. A cushion system comprising:

an interchangeable cushion cover including:

a top member;

a band portion extending downwardly from the top portion, the band portion including a top edge portion attached to the top member and a bottom edge portion;

a bottom member separate from and attached to the bottom edge portion of the band portion, the bottom member interconnecting opposing sides of the bottom edge portion of the band portion and arranged to reinforce the cushion cover against radial outward forces exerted on the band portion;

an interior space defined between the top member, the band portion, and the bottom member;

a bottom opening defined in the bottom member, the bottom opening dimensioned for insertion of a conformable cushion insert into the interior space and draining of the cushion insert while the bottom member retains the cushion insert within the interior space; and

a releasable fastener system including a first part attached to a top surface of the bottom member, the releasable fastener system being concealed within the cushion cover and selectively attachable to and detachable from a bottom face of the cushion insert.

2. The system of claim 1 , wherein the bottom member defines a width between the bottom edge portion of the band member and the bottom opening.

3. The system of claim 2 , wherein the width of the bottom member is variable.

4. The system of claim 2 , wherein a portion of the bottom member surrounding the bottom opening is dimensioned and configured to retain the cushion insert within the interior space.

5. The system of claim 1 , wherein the releasable fastener system includes one or more elongate strips forming a frame around the bottom opening.

6. The system of claim 1 , wherein the releasable fastener system surrounds the bottom opening.

7. The system of claim 1 , wherein the shape of the interior space is conformable to a shape of the cushion insert.

8. The system of claim 1 , wherein the cushion cover is interchangeable with different cushion covers adapted for different styles.

9. The system of claim 1 , wherein the cushion cover is interchangeable with different cushion covers adapted for different weather conditions.

10. A cushion system comprising:

an interchangeable cushion cover including:

a top member;

a band portion extending downwardly from the top portion, the band portion including a top edge portion attached to the top member and a bottom edge portion;

a bottom member attached to the bottom edge portion of the band portion;

an interior space defined between the top member, the band portion, and the bottom member;

a bottom opening defined in the bottom member;

a cushion insert removably positioned within the interior space of the cushion cover via the bottom opening, the cushion insert including a bottom face formed of a fabric defining a network of through openings, the through openings and the bottom opening collectively arranged to promote at least one of drying and draining of the cushion insert within the interior space of the cushion cover, and the bottom member arranged to retain the cushion insert within the interior space; and

a releasable fastener system including a first part attached to a top surface of the bottom member of the cushion cover, and a second part attached to the bottom face of the cushion insert and covering at least a portion of the through openings, the first part engaging the second part to releasably secure the cushion insert within the interior surface.

11. The system of claim 10 , wherein one or more of the through holes have a selected lateral opening dimension arranged to allow passage of air or water between an interior surface and an exterior surface of the cushion insert.

12. The system of claim 10 , wherein the releasable fastener system comprises a hook-and-loop fastener system.

13. The system of claim 10 , wherein the releasable fastener system includes at least one of a magnet, a snap, or a clip.
