For the price you are getting a solid metal frame that looks the part, with very clear assembly instructions and even an included ratchet key tool. I went for super king and the extra height allows me to store a lot more underneath which is great for small space living, however - I am 6,3" so it's easy to climb on (in fact I prefer it), but if you are below 5,7" it might be a bit more of an obstacle. 

I appreciate the flat wooden mattress supports for a more even distribution; although I kind of wish they were a hard wood instead of a soft flexible wood, since the added movement makes your mattress feel softer. Also, on the super king - the support planks don't seem strong enough to take my full weight on just 1, hopefully that will never be a problem.
