Big on style, with meticulous craftsmanship, the satin black metal bed provides unassuming charm and gracious style. Shift from beachy to Bohemian to traditional to shabby chic... it all depends on how you layer it. The base frames come with sprung wooden slats which are 20% thicker than slats provided by other manufacturers. The gap between slats is 65mm and compatible with most mattresses available on the market.
