Upper Bed
Here are some details about the upper ("Penthouse") bed. We love the panoramic view and (potentially) cross-breeze when sleeping on this bed.
There is quite a bit of extra room for elbows and heads beyond the mattress in the rear area. This unpadded area beyond the rear mattress is just fine for pillows. Here are my measurements (looking down on the penthouse bed):
We use "eggcrate" foam for both mattress sections, but we only store the piece We've cut out for the front mattress section on the bed itself. We find that there is no room to store anything above the rear mattress section when the top is down — so we store the rear piece of foam somewhere else. If we do try storing anything above the rear mattress section, the top doesn't completely close. The mattress sections themselves are 2.75" thick, of which 1" is wood (leaving 1.75" of built-in padding).
The bed hangs from the ceiling when not in use. There is more room (an extra 1.5") above the front mattress section because those two rectangular penthouse roof support pieces don't hit it like they do for the rear mattress section. (See the white padded rectangle with a metal handle on the roof in the photos below.) Here's what the front mattress section looks like with the top up & down:
