The invention provides a hydrophilic soft sponge, and relates to the technical field of polymer materials. The hydrophilic soft sponge has a developed and interconnected pore structure and a polyurethane framework structure connecting the pore structure, and high-water-absorbent resin is combined in the polyurethane framework structure. The hydrophilic soft sponge is prepared from the following raw materials: polyether polyol, toluene diisocyanate, dichloromethane, silicone oil, water, dimethethanolamine, stannous octoate, cellulose, super absorbent polymer (SAP) resin, porous adsorption powder subjected to surface coupling coating treatment, and a non-ionic surfactant. The hydrophilic soft sponge provided by the invention has the characteristics of softness, slow rebound, high water absorption ratio, high water absorption speed and high water retention rate; the water absorption capacity is high; and when the hydrophilic soft sponge is impacted by an external force, dehydration does not occur easily, and the water retention is good.
