How can I make corner bench seating

[Molofololo]

I have searched everywhere online. I want corner bench seat. Upholstered. But I don’t want it to have a back to it. So like those bench seats that you use to store toys in. But corner shaped. Does anyone have For instance a ikea hack etc that would allow me to make one up somehow?

I made a straight one out of an ikea bench, took the top off on to the side and made a new top from plywood, foam and fabric with a staple gun.

If you don’t mind it isn’t symmetrical then two storage benches pushed together into an L.

Ikea Kallax individual boxes turned on their sides? Would need to stack two for height but you could just join inside and make a lid.

Thank you. I had a look at the kallax idea and think I could maybe manage that.
