Not long lasting
Size: Full, Size: Full
Very pretty bed and it seemed sturdy at first, but unfortunately it didn’t even last a month. I use the bed regularly with normal everyday use no heavy activity or excessive weight and the middle support beams still gave out completely. It might work well as a guest bed that isn’t used often, but I wouldn’t recommend it for daily use. The frame actually gave out while I was simply sitting on the corner of the bed. And before anyone assumes otherwise, I’m not a large person. I rarely leave reviews, but this experience was disappointing enough that I felt I needed to warn others.

Engineered PERFECTLY!!!
Size: Queen, Style: With Headbroad
So the reviews are pretty accurate, this bed is UGLY!!! A bright ugly orange hahaha! BUUUUUUUT, if color is not an issue for you (like it wasn’t for me), THIS BED IS SOLID!!!
Solid wood, solid build, solid product!!! Also I want to add that the way it’s designed, it’s very hard to mess up when building. They engineered this bed that all pieces fit perfectly together when the correct pieces are placed in the correct spots. If the holes are off, switch the pieces around until the holes match perfectly! I am in love with this bed!!!

Great bed frame solid wood
Size: Queen, Style: With Headbroad
I read other reviews about this product and someone said that it was sort of orange in color and yes it was I might try and stain the wood a different color not sure but it still looks okay I am not sure if I follow the directions correctly I installed the head board with the hardware showing from the front but I switched it to the back and it looks much better now great value seems well built easy to put together the only problem I had was with the sides I had them switched the boards that are attached go to the top not the bottom other than that it went easy to follow the directions
