Best bunkie boards according to redditors

Don't use a solid material as it will retain moisture and grow mold. Humans sweat a LOT.

Just install a regular slatted bed frame. It's lightweight and inexpensive.

Edit: or possibly even this

Thanks! I've just posted a Home Depot parts list here:

The trim that you see on the left and right side is 5' (per side) of 1/2" x 1-5/8" Pine Stop Molding. They are filling a gap between my wood frame and the metal frame of the "Bunkie Board" bed foundation rails that the slats are a part of. Its adding support to the rails and protecting two of the KALLAX shelves. (if that makes sense)

The "Bunkie Board" frame foundation/rails that I used are these:

Use a bunk board.

Thanks whoever mentioned it was called a bunkie board like this. https://www.amazon.com/dp/B074TN94VV/ref=cm_sw_r_cp_tai_Gm7XCbBKBVPNG check the requirements for a foundation. Some require no more than 3 inches open between boards.

It's not that the ikea slats are horrible, its that most of them ( I believe all of them now) are bowed flexible. Problem with an expensive mattress, when you lay down, these slats start to flex downward which can cause wear or sagging in the expensive mattress. You should place it on a stable non flexible slat system, foundation, box spring etc. I am not a fan of box springs because they say that it reduces air flow to the mattress from underneath and can cause mold issues over time. I have an Ikea HEMNES bed and am giving this a try https://www.amazon.com/gp/product/B074TN94VV/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1

I read through the comments before ordering that some customers had success using it on a the Ikea Malm bed. No comments on the Hemnes, but I am going to give it a shot.

will this work for a memory foam mattress like the casper:
