Hi Nami,
Congratulations on your new latex mattress! As you may have learned, the support of a latex mattress is super important for integrity and longevity, and will contribute to the feel as well.
There is an industry standard for supporting all latex mattresses. The rule of thumb is to have slats that are evenly spaced, that are solid and non-flexible, and that there is a center support beam and leg.
For example, if the slats are 2" wide, then the gap should not be more than 2" apart. If the gaps are 3" wide than they should be spread about 3" apart.
An 8" gap is too wide, and there is a possibility that the latex (and your body) will dip through the gap, causing improper support and damage to your mattress.
This product is not showing much information on how the slats are configured inside the cloth material, and if they are solid or flexible. I would recommend reaching out, and specifically asking if it’s compatible with latex mattresses, and if they can provide more information on the structural build. An adjustable powerbase would be sufficient, or a foundation from the retailer who makes your mattress.
Depending on your location, I am happy to make other recommendations.
Good luck!
Laura
