Congrats on the condo purchase! I assume, when you say "maximum sleeping", you mean the maximum number of people in one room. I have a small cottage bedroom that we can sleep 6 in. We bought a double over double bunk bed. It also has a double trundle underneath. This is a neat and tidy way to have an entire family stay in one room. It wouldn't be an ideal situation for every day living, but it works very well for guests. Enjoy the new place! :)

As in your larger 12' x 10' bedroom, two bunk beds for children, or two twin beds (not extra-long) for adults. A narrow chest between the bunks for drawer space; a nightstand between the twins. You may want to invest in an inexpensive rolling plastic chest with drawers for the closet to add drawer space for adults.

Hi, stars68! How many guests are you planning to accommodate in this room? If you plan on three adults, a full-size bed is not very comfortable for two. If you are planning on two guests, then you could have two full-size extra-long beds. (A daybed is the equivalent of a twin.) You need to calculate approximately how many guests you need to accommodate at any one time and how many days (in a season) they will be visiting. If you are going to have guests for 30 days, or less (in toto), I would suggest purchasing a hi-riser. This will give you the equivalent of two twin beds, but will also free up floor space in the guest room. You could watch TV there, read, or set up a portable sewing machine. If you choose the hi-riser route, make sure to buy bunky boards for each mattress. These shallow "box springs" will protect your mattresses from rust stains and holes, as hi-riser springs are metal and the ends of them are sharp.
