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

Too good to be true
Size: King, Style: With Headbroad
Very orange, wish i would’ve read the reviews better. The two cross bars are too long so we had to drill our own holes into 2 of the 14 and make it work, one if the feet didnt have threads and i’m pretty sure when my mattress arrives it’ll hang over the bed.

Sturdy Big Kid Bed
Size: Twin, Style: With Headbroad
My son loves his new bed! He is in this "big kid" bed now and he has adjusted well. I built this with my husband and the instructions are easy to follow. It helps to have a power drill to drill the screws in quickly for the platform. The bed is very sturdy and stable and has a very classic look to it.

If you truly want a brown piece of furniture this is not it.
Size: Full, Style: With Headbroad
The bed itself is great and very easy to put together although it did take some time. The only thing I was disappointed in was the color. It was orange- not even close to being brown as it was said to be.
