We need a king-sized bed, under $500. Our current boxspring/mattress are sitting on the floor, so this has been a long time coming.

For reference, there are 2 pics of what the rest of our bedroom looks like in terms of bedding, wall/floor color, other furniture, etc. We're not looking to replace anything else, just add a bed to the mix.

The first bed is from Overstock. It has been my only option for over a year, as I like it best of anything I've found in our price range. DH likes it best of the 3, but part of me thinks it kind of looks like a hospital bed and wonder if it will "work" in the room.

The second bed is IKEA. I think it would work best of the 3, but it's IKEA and I don't know if we want to get into assembling the whole thing. Plus, I feel like we should be getting away from IKEA furniture at this point in our lives.

The third bed is off Amazon. I think it would work well in the room but it's the most expensive of the three.

Help!
