High Bed Platform Build – Need Advice on Strength and Materials

Starting to work on my bed platform and could use some advice.
Quick background:
  • I need a LOT of garage space under the bed, so I’m building it much higher than usual (~50–55" high).
  • I want it to be simple, sturdy, and as thin as possible to maximize garage height.
Here’s my current plan:
  • Use steel tubing and notches (photo below for reference).
  • Attach a sheet of ¾" plywood to the frame with self-tapping metal screws (screwed into horizontal and vertical pillars).
  • Add a 2x4 with notches
  • I’ll also have a bulkhead that will help strengthen the platform.
Questions I have:
  • Will the self-tapping screws into steel pillars hold the weight?
  • Will the ¾" plywood hold the weight?
  • Will a 2x4 be strong enough?
  • Will the size of the steel bars (using 5 of them: 1-1/4 in. x 6 ft. Steel Tube, 18 gauge.) support the weight?
I’m open to other ideas too. Would love your thoughts—especially since it’s a bit taller than most builds. Thanks!

Hi Jing - thanks for the response. My concern is that my platform (steel rods) will be much higher than yours (like halfway up your window). Will the wood and screws hold in this higher position being so far away from the bolted horizontal pillar? and secured to an almost "fake" pillar?

Mr. Hammock here once again suggesting that if you sleep solo you don't need a platform bed. Of course you should also test if a hammock is comfy for you to sleep in. Given the height of the platform the OP is stipulating a hammock could very possibly be strung high and tight enough in a 159 to be above that height when deployed. I love that a hammock doesn't require a level van for comfort and if clipped in with carabiners it can be deployed or stored very quickly.
Love the out of box thinking...just not very comfortable for me. Thanks!

Hi Alaska,
I'd suggest you mock up the platform at the height (including mattress) you are thinking about and see if you can sleep in it comfortably.

Nothing worse than a bed that is not comfortable to sleep in.

Good suggestion. We do plan to mock it up prior to a full build. However, we currently have an old truck and camper that match the dimensions we are talking about and it works well for us.

Siding w/ DIYTECH. Hard to beat a try-fold ATV ramp. Holds 1k+ lbs, lightweight, hundreds of holes for air circulation (reduces mold / mildew), can be raised on the ends to access garage, super easy install (attached to 2x6" bolted to the wall ribs). :) This is a Black Widow brand.

Its hard to argue with that...and it would be easy to find them up here in Alaska!
