An ergonomic bed lounge is made with a fabric slip-cover enclosing foam padding on a main structure that is formed from plastic sheet material to provide the required strength while keeping the weight ultra light: lighter than all-foam construction. Side arms are provided that can pivot inwardly for storage and outwardly for entry/exit, for providing different resting conditions and for comfortable accommodation of different-sized users. The side arms are each equipped with a convenient storage pocket. A lower back support pillow is removably contained in pockets provided in the slip cover in a manner that enables the user to locate and orient the back pillow for maximum support and comfort. An adjustable neck pillow with an elliptical cross-sectional shape can be adjusted in height and oriented for optimal neck support in terms of head position and attitude. An accessory lap desk is fitted with a padded underside pouch by which it may be supported on the user's legs to provide a writing surface on the top side. The lap desk contains a storage compartment that is accessible through a top cover that forms the writing surface.
