PROBLEM TO BE SOLVED: To provide a three-dimensionally knitted fabric readily restoring loss of bulkiness and deformation and keeping good appearance and cushioning property in a state in which load or stress is applied to the fabric for a long time at normal temperature and high temperature, e.g. in the case when a person sits down on the fabric or washes the fabric at a high temperature. SOLUTION: The three-dimensionally knitted fabric is constituted of knitted fabrics of two layers of inside and outside surfaces and a connecting yarn for connecting two layered knitted fabrics, composed of monofilaments having 50-2,000 dtex fineness and the fabric has 0.25-1.5 mm<SP>-1</SP>thickness index T<SB>p</SB>. Compression recovery rates after each retaining 50% compression in thickness direction for 7 days under environments of 20°C and 80°C, then allowing to stand under environment of 20°C for 5 min in noncompression state and subsequently allowing to stand under environment of 120°C for 1 min in noncompression state are each≥90%.
