The Kana Japanese Joinery Bed Is A Comfortable Sleep

Fast assembly

Most people don’t think much about the bed they’re sleeping in — they bought it who knows how many years ago and went through the annoyance of dealing with metal bed frames that fell on feet and caused yips and curses when being confronted by soft toes. Putting those bed rails together without gouging and scratching floors is no picnic for sure and most get real confused about what goes where and how to ensure that one end properly lines up with the other. So that’s where the Kana Japanese Joinery Bed comes into play: it’s a special designed solid rubberwood frame that assembles with ease and doesn’t cause a headache in the process.

Setting It Up

So with the existing metal bed frame, box spring and mattress out of the way, it’s time to get the varoius boxes that the Kana Japanese Joinery Bed comes in over to the now empty bedroom space. While Flexispot provides an online manual, the easiest way to understand what to do is to look at it on YouTube — keep in mind that the whole assembly is designed to be done well within 15 minutes — made even more efficient by having two people working together.

So we’re going to be assembling this almost like it was a jigsaw puzzle, in that there is slots to use and no tools and few hand-tooling bolts required. We start by assembling the two sides as they stand on their own and follow that by attaching the back and front sections — pushing ends sort of like they were Legos. And keep in mind that there’s just a few of those bolts, accompanied by some washers and metal plates. You do need the two people to hold up the sides so as to make it easier to lock them into position.

Then the 2 parts of the headboard get placed into position and these use the bolts, followed by the support beam being done with legs getting metal plates. This cross section is then attached to the side slots to form a brace for stability and they get bolts also. Now there’s a support system at the center of the bed frame.

Wedges now get inserted into the slats that have been aligned with the bed frame — on the video they just pop in but in our case they had to be “wedged” into position which was aided by a soft mallet. Now it’s time to place the slates down. This works like an accordion as it gets pulled from front to back and is solidifed into position by Velcro (and some serious pats to have it lie down flat). Then the second section of slats gets placed down from back to front and you’re done. Sure it might sound a bit complicated but it is not — especially when compared to having to put together one of those metal rails bed frames that always end up taking skins off knuckles. Give a shout out to the rounded and inward facing legs that help for stability in placement and avoids getting wacked against.

Flanking both sides of the bed is Flexispot’s Kana Nightstands, coming in assorted colors. It has two drawers, both of which glide open quickly and quietly. No sticking out handles as a depression in the top end of the drawer makes for a simple grip while maintaining the smooth design. They come fully assembled.
