I am not one of those people. My sister and I had bunk beds when we were kids. (She was on the top .. when she snored, I would kick her mattress .. and she would roll over and hit the wall. Her snoring stopped, mission accomplished! lol!)
No bunk beds. After big sister left my parents took our large bedroom and partitioned it to make a small bedroom for my brother. Better solution in my opinion lol :)
Even though I was one of seven kids (six of us boys), the only times I slept in bunk beds were in Boy Scout camp and the sleeper car on a train (my better half and I eschewed the top bunk and shared the bottom one - narrow and crowded, but all the better for snuggling.)
