What is the bounce rate like?
If it's low then the cluttered look works and should result in to click throughs to merchants or adsense because in fairness there's not much else to click on.
I am truly interested to find out. Coming from a design based background I see such sites and shudder. If I were on the browse for a bed I would visit, think beds...beds....beds...nope no prices, no suggestions, no info just lots of text and links - can't see the wood from the trees and then wham, just hit the back button and a potential commission is lost.
I know I'm quite blinkered and quite obsessed with neatness of a site but if on the other hand a general, non-designer, user is less fussed, doesn't necessarily see what I am seeing and is staying with you, clicking the first links they see and you're racking up your commission then great.
My opinion is nothing has grabbed me within a few seconds. Different colours all across screen and even the 'King Size Bed' page title is lost. Have to scroll down just to see a picture of a bed (no wait just seen another on the left hand side below the navigation bar - did miss this first time around). No prices, no pictures - why am I am here again, oh yes there it is - the back button. Goodbye!
Guess point is there's no focus. Get the focus and the draw-in for the click through and hopefully you'll see bounce rate reduce and commissions increase.
Do like your model but are you not tripping dup filters with so many similar templates?
