Easy setup. It does make the bed, once set up fully for sleep, firmer. However, my mattress itself i bought for it from Walmart was a no. This steel frame was a first time going with a "modern bedframe" instead of the old school coiled box springs. I dont have an issue with this item so far. Just make sure you spend the money on that mattress!
