Aditya Kids Twin Over Twin Bunk Bed with Trundle

Perfect! Just what I was looking for. It doesn't have much clearance between the bottom and top bunk but my daughter is 4 years old and is able to sit on the bottom bunk without her head touching the top.

The gap between the top bunk and lower bunk is not functional. It took nearly 12 hours to assemble this, so we don't want to dis-assemble and ship back, but my four year old son can't even sit up in the lower bunk. We have a standard mattress in the lower bunk, which is 9" (half an inch higher than the max recommended) - the lower bunk is absolutely not a functional sleep area with a standard mattress. Even finding one a few inches thinner likely won't do the trick. Bummer!

This is a rating for the standard height bunk bed, not the low version. I bought this bed through a different retailer, but wanted to post my review here as a warning. We bought this bed because we wanted a very sturdy bed that didn't wobble when climbed on, and that was made of real wood -- the bed met our expectations there. However, I must say that when we first received the bed, we had a horrible experience. First, the bed arrived in multiple boxes, and there is no explanantion as to which box holds which pieces of the bed. Once we opened all the boxes, we realized some major pieces were missing (the slats for the top bunk and 4 posts). We called the manufacturer and they said those pieces were back-ordered so we had to wait several weeks before receiving them. When we finally received the missing pieces, it took forever to assemble the bed -- my husband and I worked on it for at least 6 hours. There are many, many pieces, and the directions are not very specific. If you are thinking of buying this bed and hate assembling IKEA furniture, think again before buying it. That said, our kids (4 & 6) have been sleeping on it a few months now, and they love it. So, it was a rough process, but it ended well.
