Bed tents & IKEA Kura tent
You *could* make your own with some thinnish pvc pipe though? The kura is made with about 3/4 or maybe 1/2" pvc piping. 3 lengths of that to bend into arches over the bed, 6 brackets to screw to the bed frame to hold them in (hard to describe what I'm thinking... _n_ sorta like that?) and then she could pick her own fabric even All you'd need is some ribbon to sew thru the tent to tie around the arches and you'd be set!
I thought about ceiling curtains. My only worry is if my cats decided to use them to climb, but it's definitely something to think about.
I also had a mosquito netting kinda thing that I got from IKEA (also cheap) and had that up on the ceiling for awhile, but we have popcorn celing and I just put it up with a cup hook so it came floating down at some point. I think that could have worked pretty well had I put it up more securely, but our top bunk is pretty tall and fairly close to the ceiling so anything up there starts to make me feel claustrophobic. It also makes it harder to change the sheets.
Anyway, the latest thing I did was to take the mosquito net thing off the hoop (it just velcros or snaps or something) and put it under the top bunk mattress so that it drapes over the bottom bunk, but leaves the top bunk open. My kids both like to sleep together on the bottom bunk (it's a double) and just play on the top one so that works for us.
This is long way of saying, I'm sure you could rig up the Kura, but I'm not sure it's going to be all that your dd hopes it will, but it's cheap so you could give it a go and see what happens.
FYI...I got my daughter's tent on freecycle.
cross posted with beanma basically saying the same thing( it can be rigged).
Ohhh...found this for you. Has instructions and pix!!
I was thinking about using flat sheets for the KURA...we have not bought the bed yet, but are figuring out all the things we will need for it. I have seen the bed in person and love it. It is perfect for the space we have. I am rethinking the tent now. I also saw that in person, but am thinking about doing curtains instead.
Well we got the bunkbed. We love it. We also ended up getting the tent. The bed itself is wonderful. It gave us more floor space, since your able to make an area under bed. Right now we have an ikea organizer with the plastic bins under the bed that holds all her barbie "stuff", and her barbie houses are also spread out underneath. The bed is pretty sturdy. I can see where there are issues with changing the bedding. We have hardwood floors, so it is pretty easy for me to just slide the bed over to get to the other side. The mattress was a little weird to me at first, but my daughter still bedshares with us, so the mattress isn't a huge deal, it is comfy to her though. I also decided to buy twin jersey sheets...those have been awesome for the mattress. I wasn't sure what to get, but they are the best option besides the ones you can buy at Ikea. All and all...we are very happy with the bed.
