Question: Will a queen size mattress fit on the bottom bunk? [60 in × 80 in (152 cm × 203 cm)]
Document: Assembly took 4 hours. The main issue is the bottom bunk is big we have a newer full size mattress and it was too small. There is an extra 3 inches of metal hanging off the side. The bed is what it is cheap. It would be ok if the mattress actually fit.
This bed looks great, not difficult to put together, but two people are better than one. Be sure to read the directions through before you start, they are not very clear as to how to place the different rails. We do question the size of the  bottom bunk , it Is bigger than the 53-54 inches stated for a full size mattress. So the bottom mattress slides all over theplace. Can I use the box spring to help secure it?
I ordered these to fit in a small guest room for extra sleeping space. I assembled them myself (one 60 year old woman) in a couple of hours with just a few mis-steps from the picture-only instructions from China. Not quite as heavy duty as I had hoped. When a full-size adult climbed the ladder to the top bunk, the bed felt as though it might try to pull over, but it did not lift off the ground.
But this product is strong as long as you use it to sleep on only.We also had some issues installing the guardrails as the screw alignments were off. But we managed to screw in 3/4 screws on each side so that it was somewhat safer. This price is a steal. ALSO! Make sure you buy the full mattress sold by Dorel Home Products as well. It fits perfectly on the bottom bunk and feels extremely comfortable (for a spring mattress).
I purchased this bed for my 16 and 19 year old boys who still have to share a room. The full size on the bottom was an approvement for my 6'4&#34;  son to spread out a little. He can have the bigger size without it and another bed side by side taking up all their room space.
My roommate is 120lbs and is 5'6&#34;. The bed holds up very strong. I know it can support much more weight both on the top and bottom.Installation of this product was difficult. Alignment, tightening the screws, and TRYING to eliminate swaying were a huge headache. One of the mattress support bars was bent during shipping (there are over 30 of these small bars, so it didn't jeopardize the structural safety at all).
I actually returned the bed, because my order was a misstake. I thought I was buying a adult size bunk bed, its more for childrens weights though. I am giving it a 5 star review cause, amazon customer service was so great to work with when I needed to cancel the order and get my refund. Great customer service at amazon, it's a sure thing, promise!! Jeff
We got this bunk bed set for our two boys whom share a room. Ages 14 and 9. They fit well and comfortably on it. It's sturdy. I didn't put the bed together but three people did just to get it done before the boys got home from school as a surprise. They love it!
Even with a thick duvet and sheets there's about 2inches to spare on either side of the mattress (which I found somewhat annoying as the mattress does move around a bit).The frame is sturdy and the base of the upper and lower bunk provide good support (which for me was very important). All in all I would recommend this bed.
I was expecting a cheap-looking glossy finish.One last thought:  You can easily slide another 6&#34; mattress underneath the lower bunk to use as an emergency sleeping arrangement for a guest, or for your kids' occasional sleepover. If you look for bunk beds with a trundle, they can be quite expensive, so you can satisfy the same occasional need just by sliding a mattress underneath this unit...like a poor man's trundle bed...
Answer: No because a full size fits snug in the bottom bunk
