Cant speak from personal experience. But from what I've read elsewhere re: the LC sofa reproductions, a lot depends on the quality of material and workmanship employed in making the reproduction. So hard to say if $835 is reasonable as it is dependent on the quality factor.

If price is the primary driver, I've attached a link below for an LC reproduction for $760

They are offering a price of $795 but I feel their price is fair enough seeing their sofa.
In my view I liked the product and also the price.
