I have a couple of those older Ikea countertops that I used for work surfaces
in my shop office. I supported them with large angle brackets on the wall. As
far as I can tell they are still flat.
If you can do without the top in the kitchen for a while, support it upside
down on the ends in the sun for a while to see if it comes back into shape. A
possible alternative would be to put a support under the center of it when
right side up & run a cable from one end, under the support & then to the other
end. Use a turnbuckle so you can keep the cable taught.
Last time I was in Ikea (last year) they didnâ??t have the solid ones, but
particle board with veneer. Would work well if you donâ??t need to cut or route
visible edges t& have plenty of support.
Peace,

I have an Ikea desktop made with solid 1" square lengths of who knows what
wood. Probably birch or beech. It's 30 x 60 and exactly an inch thick. I don't
see the product on their website anymore but it looks a lot like this:
https://www.instructables.com/Butcher-block-countertop-table-IKEA-hack/
I gave it to a friend who turned it into a guest bed with 4 short legs. I (200
lbs) slept on it for a few weeks. There are 2 metal straps underneath to hold
the glued joints together.
Fast forward 6 months and I have it again and am using it as a kitchen island
countertop, but it has gone concave along the length, as if my weight warped
it. I don't think it's a moisture imbalance issue because it's always been open
to the air on both sides. I've loosened the metal straps but the wood is still
warped. Is this something that will slowly un-warp as the weight of the island
base pulls down on it? The base is 2 old bookcases back to back, and I've
screwed the countertop to them with L brackets. Currently the lighter bookcase
is slighty off the ground, being held up by the warpage.
I'd like to eventually bind the two bookcase backs together but I don't want to
split the countertop.
thanks,
jim
