If you are feeling brave, you can spend $2,575 on a sectional couch from Wish. This is a real, full size couch according to the description. It even includes storage compartments, lights and you can add on a coffee table separately.
The couch says it will arrive within a week or two, but in the description, there is a note that this could take 10-16 weeks to special order with some options.
This is a big deal because it is expensive and heavy. Surprisingly shipping is only $14, so it must be built into the cost of the couch. I'm not willing to spend $2,500 on Wish, but perhaps you are.
