IMMER mattress protector

The IMMER mattress protector is a Celso de Lemos down-filled cover that goes on top of the mattress. The filling is pure white goose down. The maker says the down comes from Pomerania in Northern Poland, the home of the Pomeranian goose. The maker says it selects only the best down and feathers for its products.

Down makes up 91% of the filling. There are 80 g of filling per square metre, and its fill power is 850 cuin. The smallest protector, 90 × 200 cm, holds 145 g of filling. The largest, 200 × 200 cm, holds 320 g.

The cover's cloth is percale, woven from extra-long-staple Egyptian Giza cotton. The seams are double-stitched. Celso de Lemos is a Portuguese maker from the city of Viseu.
