The question most frequently asked of our service team. Those who follow this advice need to replace the cover far less often.
1
Close the zipper 90 percent of the way.
An open zipper damages the drum and the fabric.
2
Turn inside out
Protects the top surface against abrasion.
3
Wash at 60 degrees
The core is not washed, only the cover.
4
Tumble dry on low heat
In a laundry bag, so the zipper doesn't bang against anything.
Why these parts are available individually in the first place
Conventional mattresses and pillows are disposable items. If a layer gives way or the cover wears out, the whole thing ends up as bulky waste.
At Seven Sundays, every layer, cover, and insert is available individually. This isn't an extra service—it’s the design itself. That’s why your pillow remains the same pillow even after five years.
Frequently Asked Questions
How do I know which size I need?
The cover is sized to fit the pillow, not the bed linen. Neck pillow 60 × 40 cm, side-sleeper pillow 52 × 32 cm, travel pillow 45 × 24 cm. The dimensions are listed at the top for each cover.
What is the cover made of?
69% polyester, 31% viscose; handmade and removable.
Is a second cover worth it?
If you use the pillow daily, yes. With two covers, the pillow stays covered even on laundry day. The twin pack is cheaper than buying two individually.
