As per the title: the both bed frames are larger than a standard twin (top bunk) and full (bottom bunk). More information and what I did as workarounds are below.

That said, pros:
- Sturdy. Very sturdy. It's going no where.
- Easy to assemble with clear directions and parts very well labeled
- Pro, but mostly opinion: attractive piece that looks more expensive than it was

Cons:
- Top bunk: standard twin size mattress is ~4 inches shorter than the frame, width close enough once bed was made (maybe 0.5-0.75 inch per side unmade)
- Bottom bunk: standard full mattress is ~2-3 inches narrower than frame on both sides, length fine
- Most of the build requires an Allen wrench which adds to time to build (and painful on the hands after awhile)

Neutral:
- Takes about 4 hours to assemble, which would be expected considering, but something to be aware of
- Did not have a strong smell as per some reviews
- Direction of bottom bunk can be flipped and is in directions how to do so
- Be aware all three windows for top bunk are the same height as the top rail and large, so potentially easy to fall out of if a child isn't careful/supervised
- Note this is a junior height loft, so clearance/head room for the full bed is limited
- Spacing between ladder rungs is relatively large

Additional notes:
- We used an existing 14" mattress with topper so head room is extremely limited. Based on experience, would suggest an 8, 10" maximum mattress for the bottom bunk
- Purchased a 6" memory foam mattress for the top, did not immediately notice any sagging between the slats which are 4" apart, but purchased a bunkie board for the top bunk for additional support (maybe not necessary, but the spacing is enough with a non-spring mattress for concern). Top bunk can easily accommodate an 8" mattress with plenty of safety railing left above it.
- To resolve lengthwise gap in top bunk, purchased a trianglular bed wedge (VEKKIA Twin Size Bed Wedge Pillow) and placed it point-down in the gap at the head of the mattress which closed the gap nicely
- To resolve the side gaps on the bottom bunk, determined space between corner supports of frame is 38" and filled gaps on each side with two bench cushions (one on each side). Purchased "Klear Vu The Gripper Non-Slip Tufted Omega Universal Bench Cushion, 36 inch."
- Due to not having a headboard plus frame creating space between head of bed and wall for bottom bunk, purchased another bed wedge to fill in the gap
- "Modifications" with cushions and wedges cost an additional $140 plus $60 for the bunkie board, which is something to consider into the price. In retrospect, I may have chosen a different bed at that higher total price point to save the aggravation of the workarounds.

My child absolutely loves the bed and beyond having to solve for the length/width issues, I found the assembly a breeze and believe it to be a solid piece of furniture.

My son loves his new bed! He's 4 and has some difficulty climbing back down but he's learning. I wish ladder steps were wider so it was easier to climb up and down. One thing I did not think about was how to get sheets on mattresses. We have the bed in the corner of the room and it is difficult to change the sheets. It's definitely a work out but he loves his bed so much it's worth it. Plus this is real wood!!!! It does have the real wood smell for awhile but we loved that about it. Most furniture these days isn't the real stuff. Wasn't difficult to assemble but definitely a job for 2/3 people. Just pay close attention to which side of the wood has the varnish and which side is painted. It does matter when assembling though they look a lot alike.

I ordered this bed on April 21st and it arrived to my house on April 27th!!! I didn't have amazon prime so to me the shipping time was AMAZING!!! I'm super satisfied with the quality, the sturdiness and just overall I'm loving this bed so far for my son!! It took my fiancé 3 hours or so to build it, but he didn't have any complaints it was sooo worth it! I saw some reviews on this talking about a strong odor, but to be honest it smells like fresh wood so I'm not sure what others are talking about because im almost positive that it's not a chemical smell it's just a strong smell of newly bought furniture. I plan on buying another bed from this company for my daughter here in a few days!!! Thank you so much!!!!!

Had this bed going on 3 months now I think and my 2 boys love it. They're 4 and 2 years so it's perfect for them. The smell from the packaging did take about 1.5 months to go away completely but for the price and quality of this bed that's a deal! It also doesn't take up a lot of room and is way sturdier than I expected. It was a little hard assembling it solo but if 2 people do it it's easy. The only thing I will say that was annoying was..some of the screws for the slats ABSOLUTELY would not go through the wood..and I used a power drill. I managed though. Also the shipping process was annoying because amazon doesn't specify number of boxes too expect so Amazon should probably do that. Otherwise, such a cute bed! Definitely buy this bed here because I price checked EVERYWHERE and this was THE BEST PRICE by far.

Bed took almost 5 hours to put together (two of us) mainly because the hardware was very difficult to install. Predrilled holes lined up fine, but they almost weren't big enough to fit the screws provided. It took every bit of my husband's strength and the use of a vise-grip locking plier (at times) to get those bad boys in. The tiny tool provided is just not enough. Other than that, it was fun to put together - the instructions were clear and easy to follow. It's a big hit in our house! The bed is for our 3-year-old son, but our 6-year-old daughter is loving it just as much as he is! (Tried to upload photo but error with file. Sorry)
