With our adult son out on his own, we want to update our guest room situation without spending a fortune, since we'll probably be downsizing in 5 years or so.
We have a 4 bedroom home - all BRs on the 2nd floor
1 master BT
1 large BR that serves as my husband's office for several businesses (computer, fax, files, etc.) with 2 closets for biz supplies and off-season clothes, I don't want to mess with this.
1 good sized BR that was our son's, that currently has a good quality full size bed and my keyboard/music files (I sing in some choirs and need a place to practice)
1 smaller BR that currently has a twin bed, a dresser and a tall bookshelf
I'm thinking of moving my son's full bed into the smaller room, and getting a trundle bed for his room that can open up into a king bed for guests. Putting guests in the double bed just isn't feasible, and it's not all that feasible when our son comes home with his girlfriend. And we have guests expected in the summer. So a smaller bed would work for most of the time, with a king option for special occasions. Friends had trundles for their daughters which were easily popped up into kings when we visited or even when the kids had a sleepover, and they seemed to work well.
So, have you done this? I see prices all over the place, and I'm looking for an easy-to-pop-up bed to use maybe 6 times a year (not every weekend!). I'm willing to buy mattresses separately (I assume that's how it's done although I wonder if some of the expensive sets include mattresses). Some trundles are sold as day beds which function as a couch mos of the time, but when we had a day bed in the past, it was a huge pain to make and for guests to get into. That's why I wonder if a basic twin bed would make sense, with a trundle option.
I think storage underneath might be useful for the pillows and blankets, so I wonder if that's a good option. Anything I need to know? Have you bought on line, from a furniture store, or what?
ETA: I understand what a day bed is. I saw some with drawers underneath the trundle part, but that made me think there was no hardware to pop up the trundle to be regular height, just a flat surface with drawers beneath. So I thought that might be good for a kid's room where the 2nd child (like a sleepover friend) sleeps on a lower level, but I know it's not appropriate for an adult.
