A "compliance" can not be expected from this slatted frame - at least with "low to medium" body weight. In our case this is desired, therefore, it fits perfectly.
Who something "sprung" preferred needs probably take thinner slats.
Reminder: Double Latte thickness => 1/8 of the deflection. (If all other parameters remain the same)
One must therefore not underestimate the difference between 20 mm and 16 mm (=> about 2-fold) OD. 14 mm (=> about 3 times) Deflection
