How do i change a full box spring to fit a 3/4 wooden antique bed fram

Hi. Hold onto the 3/4 until it's time to replace the full. There's no DIY for cutting down a mattress.

I don't know of a way to change the size of a "spring" mattress. Could you creatively rework the antique bed, like just using the headboard and footboard attached to a full sized base frame? Just a thought...older beds sometimes don't need the height of today's mattresses and foundations...so also measure what the antique can handle in thickness as compared to total thickness of your current mattress and box spring/foundation.

A lot of antique beds use wood slats (and maybe a bunkie board) instead of a box spring under the mattress. You can make your own bed slats using hard wood boards cut to fit side to side in the bed frame.

We have double old antique iron beds.....extended the rails with plastic plumbing pipes by a few inches taped on to the foot of the bed side rail....then i have a queen size matterest.....it just hangs over......have had it like this for 25 yrs.....i also sell antiques. So if you can....just let it hang over. Also, i am too tight to have a special mattress made for all my antique beds....i am a collector also, and live in a 1865 saltbox house.

I went to our local mattress company and had them make a mattress and box spring for my 3/4 bed. They only charged me the cost of a full size bed plus $75 to custom fit it to my needs.

Hi NO i don't.....but your mattress will just will lay on the bed and the sides of the matress will just hang over the sides. If the bottom part of the mattress falls thru......there was a lip inside of the frame.....we put boards across the inside so it would not fall thru....Forgot we did have a antique wood bed for my son's room. It was from the 1940's High headboard....and the end of the bed curved....we painted it a forest green and cut mooses at the top of the headboard.... We did the moosey lodge them....Had a old painted boat....someone put shelfs in....went to a sale and bought a moose head and old fishing equipment.....Gripped all the time about this look sold it all.....then a couple of years later....wanted it back...told him forget it it was too expensive to redo. Did the room now in old retro lockers.....those are heavy. Old lighted beer signs and and old 45 records hung on the wall found a old Mt Dew sign for the his room...........But back to your question.... any mattress will fit on those beds....i have never had one custom made way back in 1987 (this is how long we have been in this 1865 house) they wanted $700 to custom make a mattress. On the new matresses you have to worry about the length fiting. So exteding a wood bed...if it does not fit.....have to extend the sides....

On wood fit it in place on 1 end.....then get little chunks of wood and put them under each side of the bed....where totes will fit under the bed....i have totes under mine because i have no storage/closets in this house......by raising the bed....the totes will hold the side rails of the bed in place.....so then.... you need to cover all that up with a bed skirt.....they are expensive new.....soo i was at a auction and bought (can look on ebay or etsy) for old sheets or table cloths usely need 3 of those....this bed sheet is a little fancy.

I see i cannot put links....found this on ebay item # 250861528208.....Click on these pictures to make them bigger or Zoom in

seen i could not put links......These will make your bed skirt....line it up to floor.....and there is your bed skirt. Play with your own mattress and see how it is going to fit....and the adjust your bed without cutting the bed or the mattress... so it will fit.

Just seen that this is a full size bed....then put a mattress that you have to fit......full or queen.....do you have a picture of the bed? also the inside of the bed and the rails.....then i can tell you also if you can make this work. I have sold all my old wood beds we have used....and we just have old iron beds now.

Lay a piece of plywood (or more) over the rails on the sides of the 3/4 bed and place the double mattress on that, But first check to see if length is the same. We just found an adorable cot sized bed and will have to put that around a cot sized mattress/springs we have.
