Päällislakana

Päällislakana is a flat bed sheet that serves as the top layer of standard bed linen. It is placed over the fitted sheet (aluslakana) and under other coverings such as a duvet, blanket, or comforter. The main purpose is to provide a clean, washable barrier between the sleeper and the bed coverings, contributing to comfort and hygiene. A päällislakana is typically rectangular and sized to fit common bed dimensions (for example single, double, queen, and king).

Materials commonly used for päällislakana include cotton, cotton blends, linen, and flannel. The fabric can vary in weight, weave, and finish, with popular options such as percale, sateen, or plain cotton. Some sheets may feature patterns or embroidery, but many are plain and color-coordinated with the rest of the bedding.

In use, the top sheet is usually tucked around the mattress and sometimes folded back at the head of the bed. Its presence allows sleepers to change the top layer without removing the duvet or blanket, and it can be easily washed or replaced.

Care and maintenance depend on the fabric. Most päällislakana are machine washable at temperatures recommended on the care label, typically around 40–60°C for cottons and lower temperatures for delicate fabrics. Tumble drying or air drying instructions vary with material.

Usage of a päällislakana varies by region and season. In Finland and other Nordic countries, it is commonly part of a layered bedding system, though some households may opt for sleeping without a top sheet in warm weather or according to personal preference.
