4、shed foundations and mattress constructions. Data devel-oped is for comparative analysis with no pass/fail criteriaapplicable.1.3 The durability test (Section 7), impact test (Section 8)and firmness retention test/surface deformation (Section 9)require upholstered samples. Firmness testing may be ra
