When I was looking for a new sofa. I came across the LON sleeper sectional. I was looking for a couch that would be comfortable and modern, but getting sleeper was a bonus. The sectional is firm, very firm 

and roomy. It is nice and modern looking and I expect years of use out of it.  I wish the legs were beefier, otherwise great purchase!!

Update:  This sectional is extremely firm. I mean extremely. I love it aesthetically, however and the comfort sometimes gives me buyers remorse. I hope if gives for the sake of wasting money.
