There are 10 slats (~108cm length, ~9cm width, ~3.5cm thickness) on my bed right now spaced at ~11.2cm. Unfortunately, these slats are spaced too far apart and will void my hybrid (pocket spring with foam comfort layers) mattress warranty and it is generally advisable to have slats spaced closer together to provide better support for the pocket springs and reduce sagging risk.
I am planning on adding extra slats of width 6cm to the bed: 1 in between each existing slat, so there will be 9 extra slats in total. However, there are wooden spacers between each slat, as demonstrated in in the image below. The wooden spacers have a width and thickness of ~1.6cm. Two options come to mind and I am not sure which would provide better strength:
- Adding extra slats of thickness 3.5cm like the existing slats but adding a notch at the ends so that they can fit in at the side rails.
- Adding extra slats of thickness 1.9cm without a notch and resting them on top of the wooden spacers
Which would you recommend? Are there any alternative options that are relatively simple?
