Sleeper sofa shopping?

Looking for somewhere to get a new sleeper sofa. Mother in Law is coming August 8th and she’ll be sleeping on it.

Ideally cap at $1500. I live in the loop but not worried about having to drive out to get it.

We really like the Friheten (https://www.ikea.com/us/en/p/friheten-sleeper-sectional-3-seat-w-storage-skiftebo-dark-gray-s69216757/) from IKEA but they’re sold out for awhile.

Any suggestions?
