Features
- 3 Beds, 1 FootprintGive three kids their own sleep space without filling the room with separate beds. This twin over twin over twin triple bunk bed is a smart fit for siblings sharing one bedroom, weekend sleepovers, cousins visiting, compact guest rooms, or vacation homes. Note: This triple bunk bed is a fixed unit and cannot be separated into individual beds.
- Stairs with StorageThe 4-step wooden staircase makes climbing to the upper bunk easier than using a narrow ladder. Each wide step is designed with a front walking area and an extended open storage section behind it, giving kids a handy spot for bedtime books, slippers, toys, blankets, or everyday room clutter.
- Top Shelf or Twin XLThe upper bunk includes a fixed wood shelf at the bed-end area, perfect for keeping a water bottle, glasses, books, small toys, or a phone within reach when using a Twin mattress. Need more sleeping length? The upper bunk can also fit a Twin XL mattress when the shelf is not used for storage. Recommended upper mattress thickness: 6 inches or less.
- 330-Lb Metal SupportBuilt with a black metal frame and supportive metal slats, this metal triple bunk bed gives each sleeper steady mattress support without a box spring. Each bed supports up to 330 lbs, making it a practical choice for kids, teens, and overnight guests in busy shared bedrooms.
- Guardrails & AnchorsFull-length guardrails help create a more secure upper sleeping area, while included anti-tip wall anchors add extra stability for daily family use. This 3-person bunk bed comes with clear instructions, tools, and hardware for assembly. Ships in 2 separate boxes, which may arrive at different times.

This bunk bed frame took about 2 hours to help with a second person helping. Instructions were very clear and all parts came with it. Very sturdy and strong. I ended up putting a thinner twin mattress on the top because the thick one I had just didn’t look too safe it was almost the same level as the guard rail by a couple of inches and my 7 year old likes to roll over and move a lot. The top is also sturdy my husband got on there to fix something (195 lbs) and it seemed very strong. Although I wouldn’t recommend to have that weight on the top always unless it’s for a reason but at least we definitely know it’s strong. It’s noise free and the space between the top and bottom bunk is enough to not hit your head I can sit on the bottom mattress without my head touching the top (I’m 5’3) roughly 200 lbs. overall nice purchase and I like that the ladder can be on either side .

Don’t over tighten the screws support flats may break and poles will warp However while mounting leave them loose and tighten at the end Remember to build in the room that you are going to put it in as it may not fit a regular door If you are substituting another bed in a small room you may have to take the old one out of the room first as both might not fit in the room

Right out of the box the assembly wasn't too bad but several holes were just far enough off to make putting the bolts in a nightmare. A few spots were completely welded upside down (such as a ladder spot, several in a row correct and then 1 upside down, then more correct) ultimately the few that were messed up were not threaded spots, just the flat tabs where a few pieces junctioned, and weren't going to affect much as only the ladder one was in a weight bearing spot, so I just used a metal drill bit to put the hole where needed and it assembled it. The issue was it was a little rickety right out the gate, but seemed solid enough for my small 5y/o and my average 7y/o. I was wrong. Within just a couple months the ladder pieces broke (ironically the ones that were "correct" to start with broke first) I was annoyed but used some metal screws and 1x2s and just filled the gaps, since the rest of the bed was holding up OK. Fast forward to now, exactly 6months after purchase, and the bed rails are all sagging despite nobody over 60# ever even sitting on the beds, the safety rail on top snapped off the metal at one end (again ironically one of the "correct spots") the ladder came disconnected at the bottom, creating a serious Hazzard, and the whole thing swayed like a hammock every time my sons climbed in either bunk. I tried tightening the bolts to no avail, they just loosened back up the next day. I finally decided to give up and buy new wooden beds instead. This was a waste of money and could have been a serious problem if I didn't tuck them in each night and notice the things breaking. Don't waste your money. People may not have the issues I did at first and write a great review on the first day or week, but I'm telling you, 6 months in I'm having to toss them with only use by children under 60#. The only parts that survived were the parts I ended up fixing. This bed and its loft counterpart are both trash.

Very sturdy and easy to put together. The finish looks top notch as well. We will see how it stands up to my two grandsons. The price is right as well

First off, it looks really nice once it’s put together. The black metal frame gives it that clean, modern vibe, and it doesn’t make the room feel crowded, which I was worried about. It’s also actually pretty sturdy once everything is tightened properly. No scary wobbling or anything like that, which is a big deal for me.
