    I was asked, what was the total time and investment, it was roughly this:$4,000 total USD:- $1300 for the floor (Those squares are $45 ea, and I bought over 30).- $2700 for the box- about 9 days of labor (I am slow and careful), the last two days were moving it upstairs and assembling it.And could a cheaper version be built:?You could save cost by using cheaper (lower grade BCX) plywood (maybe $400 saved), and skip the floor if you don't have downstairs neighbors, brings it in below $2500.I would not skimp on the sound proofing materials themselves. Same for the latches and hinges, stick with the good stuff.Also, now that winter has arrived I can comment there. Since I have sleep apnea, and fresh air pumped into my nose, I tried leaving the fan off and my heater off too. And yes, it ...

Since I have sleep apnea, and fresh air pumped into my nose, I tried leaving the fan off and my heater off too. And yes, it is toasty warm when 50 degrees inside the room, so it will save me some heating bills. Even with the fan on low, it still gets pretty chill inside if it's 50 in the room. That fan really does well given how quiet it is.

    It depends on the frequency of the snoring, the lower the frequency the more likely for it to get through. Snoring doesn't go below 100 hz, so likely it would block most of it:.https://www.ncbi.nlm.nih.gov/pubmed/12071989.From the article, different snoring types have different frequency ranges, the lower it goes, the more difficult to block..If a (hollow) bedroom door can stop it, that's a pretty good sign, as the box-bed is more effective than that.

    Here is the sleep report:.It's only moderately effective at the low frequency thumps and bumps, it does help, enough to be worth it, but does not stop all low frequency noise. I was hoping for better, but it is the hardest problem acoustically to solve..Moving up a bit in the frequency spectrum, dogs, garbage trucks, road noise, voices, it stops cold, frankly better than expected there, even with the ventilation ports..The ventilation is also quite effective, I was worried that fan wouldn't move enough air, but it hits the sweet spot for a barely felt breeze, and keeps the inside temp about the same as the outside temp when on high. I haven't experimented with turning it down to see if it gets warmer inside yet. We haven't hit the depths of winter yet, but I do anticipate it will sav...

    Just for fun, I am told some of my ancestors (notably my grandfather) slept in these as a child:.https://en.wikipedia.org/wiki/Box-bed.It seems I have rediscovered my roots.

    Here it is in the living room disassembled, thanks to the neighbor's sons for helping me carry it upstairs. I got my garage back too, that's it all cleaned up..Hoping to install it in the bedroom tomorrow.

    Here it is mostly finished, needs a velcro strap to hold the door closed from the inside, and the fan mounted. But it's ready to begin moving it upstairs tomorrow.

    And then there were two....Two panels left to cover on the inside, probably be done tomorrow, and move upstairs over the next day or so..

    Lost another day, the Amazon glue shipment was a day late. So yesterday was a thumb-twiddling video-game kind of day. Fortunately the glue arrived this morning (Sat). I am now about two days behind my original planned schedule, so this will go into next weekend unfortunately. Some neighbors came by my garage and dubbed it a sleeping pod. I am calling it 'the coffin' to my family. So far it has been quite enjoyable to build, I just hope it actually works..Appended are some progress pics for today, only four panels are left to be covered, and it will be ready to move..Moving it upstairs will be a whole day I think. I ordered some single person appliance carry straps. While no panel weighs more than 70ish lbs, and all but one panel should be in the 50-60 lbs range, they are large ...

I ordered some single person appliance carry straps. While no panel weighs more than 70ish lbs, and all but one panel should be in the 50-60 lbs range, they are large and bulky and the straps should help reduce chance of injury and accident..Pics include the foam sizing notes so the panels will line up right, various shots of panels being covered,the first two fully covered panels standing up. Guess which one is entitled 'patchwork'..

    Day 3, falling behind, worse, one spray can of foam cement barely covers a 4x4 area, so I need to emergency order 20 more cans. Won't arrive until Fri. Was hoping to be done on Friday, but it's going to push through the weekend for sure..But what's there looks good, the blue closed-cell foam is easy to work with, cutting it is like cutting a steak with a knife..The door is looking good, it closes perfectly with no effort and no squeaks, glad I got high quality heavy duty gate hinges, and a decent door closing spring..The ventilation fan and the hole for the CPAP hose intake are there, so all wood cutting is done, the top bar above the door is so I can grab it, it is reinforced to support my weight.

    End of day 2, roof is on, door is framed and hung, but I didn't have time to put it on for the pic..A few more shots of the construction too. The hard part was matching the door hinges, I put the side panel and the door on adjacent tables and that made it easy, The reinforcement for the door hinges is 1x3.5" maple board..The assembled pic is after it gets dark, I go until dusk, garage isn't well lit at night..Tomorrow will be finishing a few framing bits and hopefully most of the day will be gluing foam to the outside.

    Here is the first day, the sides are up, the door and roof are next. Proud of my tools, the right tools for a job makes the job much easier. That little Rockwell circular saw is new for this job. It's a small light-duty circular saw, it's holding up so far and delivering great cuts. The low-power adjustable-torque electric screwdriver with the socket driver is fantastic for driving the bolts to hold the latches. That Craftsman electric drill is about 30 years old and still going. I have a newer one but I keep using the old one to see how long it will go..The bed frame was a disappointment, it has raised rails unlike the pic on Amazon, so I had to fill the sunken area with MDF board (required a quick trip to home depot). Every smaller HW store near me is now out of business, so it...

Every smaller HW store near me is now out of business, so it's Home Depot or HD supply, both large warehouse-style stores, I miss smaller neighborhood joints..Tomorrow I hope to hang the door and start gluing the outer foam layer on. Once the outer foam layer is there the outside will be complete. I'll pad the inside last.

    Tested the glue yesterday. Turns out the 3m 74 foam spray is basically contact cement in a spray can. It comes out a little runnier than the canned stuff, so it soaks into foam a bit, meaning it works as advertised. It didn't melt any of my foams and adhered to everything well, so I ordered a bunch more cans. Tomorrow I find out if I can get next week off to work on this since everything should have arrived by then.

    Here is the first round of big stuff: the foam tiles and the memory foam.Love how the UPS guys carried it upstairs for me. I managed to open the door and push the stuff through with only minimal rearrangement of the boxes.

    The materials start trickling in today..My neighbors continue to try to be quiet, and mostly succeed, but fail often enough I am not regretting going through with this yet. The roof has been mostly quiet too, but I have had two sleepless nights from the roof in the past month or so, and it is expected to get worse as winter approaches. I just hope when this is done it attenuates the noise enough to have been worth it..I also found a speed controller for the fan, 0-800 RPM, with a switch to set the minimum RPM to 300, luxury and safety in one go..https://www.amazon.com/Noctua-NA-FC1-4-pin-PWM-Controller/dp/B072M2HKSN

    Here's the parts list..I have decided to abandon bolts and braces to join the 4'x4' panels, in favor of latches, this will make the whole thing much much easier to assemble and disassemble on the fly, The mattress will be a tight fit on the sides, so changing sheets may require the side panels to come off:.Rated at near 1000lbs ea, these should do the trick:.https://www.protex.com/60-655M1MSZN-YP-adjustable-....The variety of catch plate forms means they can be used for both straight and right-angle joins..The door (a 4x'4' panel) will need some heavy duty adjustable hinges, spring-loaded gate hinges seem to be the best for this application:.https://www.amazon.com/Closing-2-Pack-Finish-Adjus....They accept 1/4" bolts (I will not use wood screws, but drill holes, and use bolts, wash...

I won't be cutting the base, but the side and top panels will be 4'x4'..Some various tools (Rockwell small circular saw from amazon, with plywood specific high toothcount blades), and nuts and bolts from boltdepot..To glue the various layers I will be using contact cement, from the local OSH (Orchard Supply) or Home Depot. It comes in pints, I expect to use more than one..Spray paint for finish (to match the blue of the outer foam), will likely come from OSH.

    The foam pad came in, looks like a winner, it's closed cell and has both reflective and dampening properties, here it is:https://www.amazon.com/Incstores-perfect-lightweig...I am planning on painting the non-blue exposed bits to it looks better.The side-wall and top-layers will be:- foam pad (outside) outer air-tight reflective and dampening layer- 3/4" ply - the mass layer.- memory foam (2-3" 5 lbs/cuft) - this is the viscous/air layer, is porous, absorbs low-frequency sounds when sandwiched better than anything I have found so far.- foam pad (inside) inner air-tight reflective and dampening layer, doubles as the inner 'mass' layer, but isn't very massive unfortunately.I would prefer a mass-air-mass design with MDF board, but that would add too much weight, enough it could cr...

This will keep the whole thing to 500 lbs, not more than about 100 of which could fall on me. And it will be very softly padded so I think that will be fine in an emergency.I will need to test the smoke alarm that I can hear it inside this thing, that's going to be interesting.Now for the base:I found some excellent 2.5" thick rubber tiles for the vibration damping base:https://www.audimute.com/peacemaker-soundproofing-...I think I'll go big on this and cover the whole bedroom floor with it, it vibrates like a drum head, so it makes sense to dampen the whole head, not just a small part of it. It's heavy, so I investigated what appt floors are rated for, and I won't be above 25% load including everything in the room.
