Washable and removable chair cover: The hanging seat cushion includes a zippered cover for easy removal and washing. The inner filling is reinforced to keep the cotton threads from loosening when you remove the cover. 15 cm thick padding: The cushion is padded with high-elastic PP cotton. 15 cm of extra thickness provides a soft, comfortable feel. This thicker cushion offers a less rigid experience than a swing or wicker chair, helps prevent hip widening, provides good rebound, reduces hip pressure, relaxes the hips, and delivers a softer, more comfortable sensation. Adjustable headrest: The outdoor hammock cushion comes with a headrest that can be positioned to suit your needs. It conforms to your head and helps relax the neck. Non-slip straps: The cushion and pad feature anti-slip straps to secure firmly to the hanging basket and prevent movement. There is no risk of them falling to the ground and getting dirty. The concave-convex thickened design fits the curves of the body for added comfort and pressure relief. Use scenarios: - Relax in a patio or balcony hanging egg chair while reading, sipping coffee, or enjoying the sun. - Use in the garden or poolside for a comfortable nap after outdoor activities. - Bring to a campsite or outdoor lounge area for steady, cushioned seating and neck support. Materials and compatibility: Washable cover, inner PP cotton filling, anti-slip straps. Designed for hanging egg chairs and similar hanging basket loungers. 15 cm padding and headrest provide ergonomic support and comfort.
