How to keep Chase cushion from leaning? It tilts down at t?

You could add velcro to the cushion and the chase. That way you can still take the cushion off and wash it.

Hi Julie. Trying to think outside the box. You could use magnets to keep the cushion in its place. You could glue the magnets inside the fabric using a strong adhesive like Gorilla Glue. Good luck Julie. Hoping all is well with you.

It’s not sliding off, but tilting down on one side. Like the cushion inside the zipper Med cover is wearing down on that one side, and it’s only 2 years old. I can’t turn it over because it won’t fit any other way.

It’s just looking smushed at one end? Is it foam or fiber filled? If it’s foam, maybe try manipulating it around. If it’s fiber fill, try adding more fill. It could be there’s a problem with it, maybe have an upholsterer replace the insides.

I agree with Becky. Adding foam or fiber fill is the best solution.

To have most longevity, upholstery foam must be the right thickness and density for the function of the particular piece of furniture.

From how you describe the problem, I would say that the foam filler inside your chaise cushion is not dense enough to withstand the constant weight and pressure of the feet on it.

Try adding fasteners to the back side. Ties or hook & look (velcro) would work.
