Computer Room Design

I’ve seen websites and software where you can build a room with specifications and then put items (beds, couches, chairs etc) in it so you can see a full design. Where can I find these websites, or the software?

hi, im designing my new room in our new house and its been really hard doing that on paper because if i want to move the bed or change any of the sizes and measurements i end up having to do it all over again.

so i was wondering if there is any designing software thats really simple to use that i can download for free from limewire.

i tried autocad but that was waaaaaaaaaaay to complicated for me i want something really simple like “paint” for example, just instead of choosing lines and colours i want to choose different beds and furniture.

thank u soo much for your help
