The edge protection sponge 4 fits well with the covering layer 3 and the core 1. The edge protection sponge 4 is made of extra-hard sponge. The thinness of the edge protection sponge 4 can ensure good support strength and reduce the unpleasant experience caused by the elasticity difference between the edge protection sponge 4 and the pocket springs 12. The pocket springs 12 of the core 1 are divided into main springs and edge protection springs. The elasticity of the edge protection springs is slightly greater than that of the main springs, which improves edge support while reducing the unpleasant experience caused by the elasticity difference.

[0087] Example 2

[0088] The difference between Example 2 and Example 1 lies in the bed core 1 and the corner protector sponge 2.

[0089] See Figure 10 In this embodiment, the bed core 1 includes non-pocketed springs 12. The corner protector sponge 2 is formed by bending a rectangular sponge 41, and the two folded edges of the corner protector sponge 2 are inserted into the gaps between the non-pocketed springs 12.
