I'm ready to purchase Mohawk Smartstrand carpet for a master bedroom. Does anyone have an opinion on thick-weight vs mid-weight carpet? We will use a thick, almost memory foam pad and there are no pets or children. The thick weight feels noticeably better than the mid but that may be just an over-reaction to the sorry carpet we are soon to replace. The dealer recommends mid-weight and states that is mostly what they sell. Part of me says it's a waste of money and the other part says, don't be foolish, get what you want. Any thoughts will be appreciated. Thanks.
