Topic tags/keywords: bed platform bed design stability question

Hi everyone,

I’m trying to design a bed so I don’t have to go out and spend $1000 for the same thing in MDF at a furniture store. However, I’m having a bit of trouble visualizing how stable my bed will be. I could go all out and reinforce the heck out of it, but I’m trying to get as stable a platform as possible using as little lumber as possible.

Below is my current (5th or so) revision. I did away with 4×4 corner blocks, hoping that extending the 2×12 legs all the way to the end rails will be stable enough. Was this a mistake, or do you think the bed will still be laterally stable enough so the legs don’t buckle under the weight of a mattress and two sleepers?

Also, I should note that I’d like to be able to disassemble this sucker fairly easily if/when I move, so I’m considering careful placement of bolts

Here’s another option, with a corner support block. This method might allow me to better hide a bed bolt, if that is even necessary for added stability.

I think you’ve solved what you’re asking with the center support. You might want to run two instead of one—one centered underneath each sleeper. That way, most of the weight will be on that support and won’t sag.

Thanks Dan, I’ve considered the double support since it’s a king bed, and I may still go that way since I plan on using the cheapest material possible for the slats (1/2” plywood, probably). Besides, one extra 2×4 would be pretty cheap.

However, my concern is more with lateral stability, ie side-to-side movement.

Have your say...
