Slatted bases offer great support to the back area as they're able to adapt to various amounts of weight placed upon them. They also offer a good level of ventilation giving even amounts of air circulation to your mattress.
What is better slats or solid base?
Bed bases with a slatted structure lend well to a spring bases mattress where as a solid structured bed base such as a plywood platform top would compliment a dense foam mattress better. Overall choosing the right base and complimenting mattress will prolong its life expectancy making your investment last longer.
Do bed slats break easily?
Individual slats are highly sensitive and can break easily with excess weight. If an overweight person kneels on one of the slats or bends in a way that places too much pressure on one slat, it may break.
