There is disclosed a seat cushion (10), including a forward portion (22) for supporting the upper thighs of a sitter. The forward portion (22) is formed from at least a first resilient material. The seat cushion (10) further includes a rearward portion (24) for supporting the buttocks of the sitter. The rearward portion (24) is formed from a second resilient material, which is relatively softer than the first resilient material. The seat cushion (10) further includes an upwardly open transverse crevice (30) defined between the forward portion (22) and the rearward portion (24). The seat cushion (10) further includes a pair of intermediate portions (38, 40) for supporting the ischial tuberosities of the sitter. The intermediate portions (38, 40) are formed from a third resilient material, which is relatively firmer than the second resilient material. Each intermediate portion (38, 40) is embedded within the forward and rearward portions (22, 24) and extending across the transverse crevice (30). The intermediate portions (38, 40) are laterally spaced apart such that, in use, each intermediate portion (38, 40) is locatable below a respective ischial tuberosity of the sitter. |
