How to Build a Box Spring
Learn how to build a box spring with these free box spring plans. Easy project that is less than half the cost of a new box spring!
I recently moved from Missouri to Minnesota, and in the process Marie Kondo-ed a bunch of things. Except, instead of asking "does this bring joy" I asked "is this a pain to move?"
What item is always a pain? A box spring.
It's big. It's bulky. It doesn't bend. Basically, moving my boxspring pretty much requires hiring movers. And movers are expensive.
So the boxspring gets left behind.
In the past, I've gone and bought a new boxspring. $100 boxspring is cheaper than $1000 movers. But this time? This time I built it myself.
Total cost? $50. Win.
Ideas and Planning
I have a queen bed, so I planned for a boxspring that was 60" x 80." Here are the dimensions of other bed sizes:
- Twin: 39" x 75"
- Twin XL: 39" x 80"
- Full: 54" x 75"
- King: 76"x 80"
- California King: 72" x 84"
The standard box spring height is 9", but I really like having a taller mattress, so I boosted by box spring to be 12" tall. This is easily adjustable, so if you'd prefer a shorter or taller box spring, it's no problem.
The plans are written for a 9" queen box spring, however instructions are included for changing the height.

*I have a brad nail gun, which makes this a breeze. If you don't, you could always use a hammer or screws and a drill/driver.

DIY Box Spring
Step 1: Make All Cuts
Per the plans, make all cuts for the boxspring size you desire.
Step 2: Build Support Beams
Three main support structures run the length of the boxspring. Start by lining up (5) 2x4 pieces along a 1x4:
I eyeballed the locations, doing my best to space these evenly.
Then put a line of glue along the top of each 2x4.
Place the second 1x4 in place, and secure with brad nails.
Filp the 1x4/2x4 structure over, and repeat with the second 1x4.
Repeat for the other two support beams.
Step 3: Assemble
I highly recommend assembling the box spring in place, on the bedframe. That way, you don't have to worry about getting the thing from wherever you built it into the bedroom.
Start by spacing the support beams evenly so that they create a space 60" wide. Take two 1x4s and use them to attach the ends of the support beams together. See picture below for 1x4 placement.
Be sure to repeat this on both ends of the box spring.
Then lay out the remaining 1x4 pieces on top of the box spring, spacing them out evenly. I eyeballed this, but I actually think it would have been easier to measure.
Secure in place with wood glue and brad nails. Then the box spring is done!
Will this void my mattress warrenty?
Probably. Despite the fact I designed the boxspring to be pretty much structurally identical to boxsprings on the market, mattress manufactuers look for any reason to void warrenties.
Any DIY boxspring is probably going to void the warrenty. I'm sorry.
How long does a DIY box spring take to build?
If you're working with wood glue and brad nails, under two hours. The bulk of the time is in cutting the pieces.
If you don't have a nail gun, and are using a hammer or driving screws, it'll probably take a bit longer.
I learn better with video. Do you have a video of this project?
Since I just moved, I didn't have any scrap wood to use, so I bought all of the lumber new. Here's how the cost breakdown worked out:
(17) 1"x 4"x 8'
(3) 2" x 4" x 8'
I purchased the lumber from Menards (rebate-happy Midwestern home improvement store,) so I will get a few bucks back in rebates, but I think $49 is a decent estimate of what a DIY boxspring should cost.
This is about half the price of purchasing a boxspring new. It's a quick project, and I think the money savings is worth the time investment.
While this isn't the most glamorous project I've ever done, it's practical and a nice money-saver.
Plus my extra tall box spring has so much nice storage!
