I have an 8 inch deep Mammoth foam mattress. I have so far been unable to find a fitted sheet that does not ride up the sides. I’ve even tried a few bits of duct tape, without success. Anyone found a solution to this problem?

velcro?

I used to have a super king and none of my bedding would stay on tight. I stitched a couple of bits of 1 inch webbing across the underside of the sheet, towards each end.

Then when making the bed, just lift up the top and slip the webbing underneath, then do the same at the bottom. You could stick some across the middle too I suppose.

John Lewis do extra deep ones.

We got an extra deep (not sure it’s 8′ though) from dreams for our memory foam matteress, it the only one we have that fits properly.. Must get another (the rest don’t fit like the OP’s)

I hear spam mattresses are great for bad backs.
