I just got these. I had someone put them onto the twin beds. The holes in the back were set up to make the headboard be MUCH lower than I wanted. They looked dinky. I have high ceilings and the short look of the headboards just did not work. I made the worker flip the legs around for the bolts to be put in the lower part of the bedframe. This may be wobbly in come cases. It worked great and I have nice high headboards. 
These are in a guest room however. If you have beds that are used a lot, then the lower height would be less stress on the wood. The manufacturer should make the wood holes flexible for different heights. All we did was flip the wood legs. There is not much support but OK for my needs. I used the lemongrass color and it is true to the picture. 
The fabric and studs are nice and so far the look is good.
