I purchased these items for my mother, who is hospitalized and has a curved lower back. They are unused. The nurses at the hospital told me that because my mother's back is curved, I needed to bring something to put on top of the hospital mattress, so I bought these products. However, after purchasing these and writing my mother's name on them, I found out that she needed a soft cushion, about 40-50cm in size, that could be placed along her body, rather than a bed mattress. I have written my mother's name on the mattress and the Seventh Pillow cover, but if that's okay, please consider purchasing them. I have taken the products out of their bags, but they have not been used. ★ True Sleeper Premier Care Single ＜Set Contents＞ Main Body x 1, Inner Cover (for protecting the main body) x 1, Instruction Manual x 1 ＜Product Details＞ Size: Thickness 50 x Width 970 x Length 1950mm Material: Main Body: Urethane Foam, Inner Cover: 100% Polyester Weight: Approximately 4.6kg ★ True Sleeper Seventh Pillow Ultra Fit Single Size ＜Set Contents＞ Main Body x 1, Dedicated Inner Cover x 2, Instruction Manual x 1 ＜Product Details＞ Size: (Approx.) 680mm (length) x 900mm (width) x Maximum Height 100mm (excluding height adjustment sheets) Weight: Approximately 1.7kg Material: Main Body: Urethane Foam, Protective Inner Cover: 100% Polyester Outer Cover: Front Fabric: 100% Polyester Side/Back Mesh Fabric: 100% Polyester Height Adjustment Sheets: Urethane Foam, Large x 2, Small x 2 ★ True Sleeper Seventh Pillow Original Cover (Single) 2 pieces Size: (Approx.) 680 mm x 900 mm Composition: 100% Polyester ※ Due to the large size of the items, the shipping label will be affixed directly to the outer box. ※ Due to the large size of the items, the packaging may be damaged during transportation.
