    I was thinking of laying a laminate floor in an upstairs bedroom on top of the existing very thin carpet. Any reason not to do this or disadvantages? Thanks.

    We put down laminate floors, though I'm not an expert by any means, so these are just my thoughts, not advice really. To my mind it does sound odd, the carpet would have to be very thin I imagine, as I'd be worried about providing a stable surface for the laminate.

    OTOH they also advise putting down an underfloor layer first for isolating/levelling purposes, so if your carpet was really very thin, could it play the same role as the underfloor? I suppose it really depends on how this carpet is fixed (is it glued or stapled?) and just how level it is.

    I would think carpet would be too thick and flexible leading to problems with flexing as you walk on the laminate.
    Most laminates are best laid on reasonably firm underlay, the 8mm I laid upstairs was laid on a green fibre type underlay and it is very firm, thin carpet would still be too bouncy IMHO.

    Yes That's what I've been thinking, our underlay was blue not green, it was for sound insulation apparently, but it didn't feel like carpet, it was more like a very thick, solid foam material. I don't think carpet would have the same effect.

    I wonder could you put the underlay down on top of the carpet though - or that only making the problem worse?

    Carpet is by nature soft, the underlay I am talking about is called finefloor, made from wood fibre. Its not really soft at all.
    Laminate works best over as flat and as rigid a base as you can find, carpet will allow the tongue to flex and you will end up with movement and cracked boards IMO.
    Lift the carpet and use a thicker underlay if necessary maybe the 5,5 mm stuff might work better if the floor is uneven.
