Very easy to assemble can't wait to test it out 😂

If you know how to pop in pieces with clicks and put about eight screws in the frame, and then lay all the crossbars into slots this thing was easy to put together. Just make sure you keep the little pieces that you screw in tight you should be fine. It's a decent build very quick.

Excellent product. I was a bit leery at first because this is nothing like the "box spring" I was used to. I waited days before putting it together because the picture showed so many pieces. Assembly was so simple that I was embarrassed for having waited. There were six main pieces, six connector pieces, six screws and a cover. It's very sturdy and fits well into a regular bed frame (my frame fits, full, queen or king). Once the cover is on, it looks like what I've been used to. **NOTE** Hold cover at bottom when placing on placing on frame so sides appear smooth. EXCELLENT PRODUCT!!!
