A topper is a thin mattress that is used on top of a regular sleeping place: a sofa or a bed. It corrects the evenness and rigidity of the bed. On folding sofas, there is often a significant difference in stiffness between the retractable part and the static part. And plus a drop in the middle of the sofa will not please your back. And with a topper, the quality of sleep on such a sofa will improve significantly: the sleeping place will be without height differences and uniform rigidity.
And for those who sleep on the bed, the topper will be for those cases when the mattress is still new and has not had time to lie down to the desired softness of the springs. Or when the springs are too felt.
The topper is fastened with elastic bands, which are sewn in the corners. UNIQCUTE produces toppers in a wide range of sizes: in widths from 90 cm to 180 cm and a standard length of 200 cm.
