There are wood, metal, upholstered, and wood and metal frames - all of which are available in single, double, king and super king sizes at Zinus. Go deeper into your choices and find thin bed frames and chunky options, beds with rounded edges and blocky, angular ones. There are literally endless designs to choose from.
The CB2 was the simplest bed frame to assemble. With only eight main components, it had fewer parts to keep track of than other, more complicated beds we tested. It took only about 40 minutes to piece together the frame, but the CB2 was also the heaviest bed we assembled (so consider skipping arm day at the gym post-assembly). Still, one tester was able to move each piece into place without expending too much sweat.
The CB2 frame required only eight bolts to piece it together (it came with a hex wrench to help) and an additional 16 bolts to secure the slats onto the frame and the center beam. Fourteen 2-inch-wide, -inch-thick pine slats are attached to canvas strips; they unfurled like a rope ladder, so they were a little easier to manage than the many individual pieces on some other beds. And of the three beds we recommend, the CB2 had the least space (2 inches) between the slats, which gives it a very sturdy build.
Zinus obviously engineered this frame with easy assembly in mind. Although it has more parts to piece together than other models we tested, the Moiz also includes the most straightforward, step-by-step instructions of any bed we recommend, a rarity with most DIY furniture. There are also identifying stickers affixed to each of the major parts. Unpacking and assembling the Moiz took us 40 minutes, about the same amount of time the CB2 model took, and we were pleasantly surprised by several small details not always found at this price: individually sealed packaging for hardware, the inclusion of extra parts, a ratchet wrench, and pre-drilled parts. 59ce067264
