DIY King size Platform bed

Gardening is winding down for the season and soon I will be doing more DIY home projects, crafts, and other cool stuff. I have a treasure trove of past projects that I hope to post over the next few months too.

Our new King size platform bed complete with the first napper

So today I am showcasing my new king size platform bed that took me months to convince my hubby that we needed. I know many of you out there know what I mean by ‘convince’. Husbands are not always willing to jump on the idea of building something with their wives. Am I right? It is a fact of life that men and women do not think a like and men have a hard time taking cues from their wives. It is the truth. My husband is the practical, common sense thinker and I am the impatient dreamer who wants to do it now…but my hubby reigns me in…

keeping me focused…sort of…

so it took me a couple months to convince him we needed to upsize (really go back up to) a king size bed. After all, we usually have 2 dogs and a cat on the bed with us. Plus we bought the worst queen size mattress in our 18 year marriage and I really needed a plushier and supportive mattress. There are two more reasons I wanted a platform bed-  I was tired of vacuuming under the bed AND I did not want the cats underneath the bed.

I have the pictures in order -step by step with measurements. The cost for 2x lumber is actually cheaper than 1x and I know it will not twist or crack like most of the 1x lumber does nowadays. The cost for the bed was around $150 which is cheaper than buying a platform bed PLUS we did not have to buy a box spring which was around $400 or more for our mattress.

Creating. Inspiring. Gardening without the rules!

After a couple weeks, I have to tell you I love my platform bed and now I do not have to worry about dog hair or cats going under scratching at the box springs. Plus this bed doesn’t jiggle or creak. It is a day project, if that, and will only take basic building skills. Good luck and have fun! Please note I may add more additional notes for building this because I lost several pictures due to computer crash. Any questions, please ask!

You will need (8) 2x12x8    (4) 2x8x8  (2) 2x2x8 (2) 1/4″ 4×8 sheet of hardwood (2) 15/32 flooring/roofing plywood 4×8 sheet

you will need 3″ screws or nails, stain or paint of your choice and it only needs to be the smallest can! not the quart size in picture

We have a planer so we planed off the outside for the stain (not needed but to stain the wood buy a stain conditioner because wood is coated and the stain may not go on properly)

Make base first which is (4) 2x8s cut (2) @ 74″ and the other (2) @ 60″ the (2) shorter 2x8s are for the end and head and are screwed or attached on the inside of the (2) longer side 2x8s

yard, bed 767

these are the measurements for the base to fit inside-cut 2 @ 62 7/8″ and 2 @ 73 7/8″ This picture is the top base which sits on the bottom base which supports the top base because of the (5) 2×8 slats are the support

For the base we are showing that you can cheat and use these angles found in the lumber aisles for decking-they are about 60cents each and easy to use

Just make sure to have the boards square either using a square or whatever method you choose

We bought this handy dandy square thingy and used it but it is not necessary

Overall cut boards for outside 2- 2x12x 84" and 2-2x12x 77"

flooring is 16" on centers and since we wanted to make sure that no sag and be able to use cheaper plywood for the base instead of that $50 a sheet stuff

Drill a pilot hole and then screw these 2x2s at the foot and end of the mattress base so the plywood has a resting edge

The (4) 2x8s for support need to be cut at 76 7/8″ the 48″ is the space between between the middle support and middle of 2×12 and the headboard and where /we /measured so a 4×8′ of plywood could go. the plywood and a smooth piece of 1/4″ hardboard cut at 76 7/8″ to slide right in there and be

the 2nd piece of plywood and another piece of 1/4" smooth pressed board is cut at these dimensions so it slides in here easily for the base and mattress to be put on.

We used the Kreg jig to attach the 1x4s which keeps the cats out from under the bed

No way a cat or other critter and hopefully dust will not end up under the bed

the wood split when we moved so hubby went back in and put a piece behind the cat deterrent. whatever your skill level you do not have to add this because it is only cosmetic and to keep critters out

2 layer of plywood-cheap roofing/flooring OSB sheets for less than $15 each and then you see the 1/4" at Home Depot for less than $9 a sheet pressed hardboard which works great for protecting the mattress from the pressed board plywood

Note! alternate the pressed board and the OSB so the seams do not match up

I used Minwax and did the pine with dark walnut to bring out the knots and grain. Pine turns yellow over time so I always use a walnut stain. You could also paint. For this we had to paint after all measurements because we were winging this!

King size mattress-so far this has been the best damn mattress I have ever had!

You can either screw the ends together from the outside and predrill pilot holes or invest in the $20+ Kreg jig. for the 2x12 lumber this is where the drillbit is set at

You set the jig out from the board the width of the board you are attaching it to

It is a great investment if you are going to build things (and we did not necessarily use the expensive screws that they suggest either)

  1. Nice job! So is it just the four 2 x 8’s that support the pedestal on the base? the head and foot end are not supported right? do you have any more picks?
    Thx Mike

    • I just realized that my updates had not saved. sorry. the base measurements are now entered and the top base sits on top of the bottom square base and is supported by the (5) 2×8 on the top base. I am looking to see if I can add more pics
