Basically, I'm looking for advice on mattresses and/or couches.

I just moved to Madison and am about to sign a lease on a 1 bedroom apartment. I have zero furniture to my name so thats going to need to change. IKEA has some sale going on through the 17th, but I've heard mixed reviews on their quality. I'm not looking for super cheap stuff, but I'm not stanky rich either. Help is greatly appreciated cause I'm a complete noob in this area and google was less than helpful. Thanks team.
