Review: Easy 45 Minute Assembly with sticky notes - I knew there were going to be a lot of parts, so I decided to be as organized as possible. After opening the box, I marked each group of items with a sticky note to make assembly as easy as possible. It took 45 minutes total to label, assemble, and put the cover on. I especially loved the mini ratchet tool that was included; it made tightening everything much faster and easier than using a standard allen wrench. Everything fit as expected and was easy to move into our rolling adjustment frame. The King mattress fits nicely on the metal box spring and does not slide around at all. It looks great and feels very solid. We are looking forward to having family visit and hope they enjoy the comfort. If you take the time to organize the pieces first and use the provided ratchet, this is a very straightforward and high-quality setup
Review: Good upgrade over wood - Upgraded an old broken down wood box spring with this metal one from Zinus. Setup was just a few minutes, and done with 1 person. Seems very sturdy, I have a larger full size mattress on top as well, and have not noticed any flexing or noise after months of use. I appreciate the fact it is metal, and will probably last longer than the standard wood box springs. My only complaint would be the top is open, so when you go to tuck in sheets under the mattress, your hand will slip in there, but super small complaint. Still 5 star item for me, because the material is good and the price is right.
