I am trying to decide which size of bed to buy for my new apt. - double/full, queen or king - I would like it to last me for around ten years, so I am wanting to make sure I make the right choice to last that long and don't have to re-buy within the next few years (cost is a factor though, as I am a full time student, so on the other hand I don't want to go nuts and pay for more space than I really need). I share the bed with four cats, and while I don't share it with a human on a regular basis at this point, I'm hoping it's not outside the realm of possibility that I will within the next ten years, so I'd like it to be suitable for two people and four cats. So, how big is your bed, and do you share it with an SO or pets? Do you feel you have enough space with the size you have, or are you cramped (or alternately, do you feel you have more space than is really necessary?). Other thoughts? Thanks!
