What is the difference between Percale and Sateen?

HHH Collections come in one of two weaves: Percale and Sateen. Percale is our most popular weave: crisp, matte and cool like a button-down shirt. Sateen is slightly thicker and softer, with a subtle shine.

Should I iron my sheets?

Keeping your sheets crease-free is all about personal preference. Whether you iron, steam or take matters into your own hands, make sure you follow our expert-approved ground rules. 
  • Ironing or steaming sheets
      • Do not dry all the way—sheets should be slightly damp 
      • Keep ironing/steaming area clean as sheets may touch floor 
      • Check iron for any dirt or residue before using 
      • Iron in segments, folding as you go
  • The hands-on approach
      • Do not dry all the way—sheets should be slightly damp
      • Lay sheets flat and smooth wrinkles with your hands
      • If sheets are being stored, fold immediately after smoothing 

How do I know what size my mattress is?

  • Full 54"x75"
  • Queen 60"x80"
  • King 76"x80"



A flange is the “wing” on a pillow or duvet – the decorative fabric that is attached to the edge where the insert finishes.


The insert is the “fluff” of the bed. It’s what you literally “insert” into a duvet cover or pillowcase – the pillow insert and duvet insert respectively. Many inserts are made with goose-down or feathers, but we prefer hypoallergenic down alternative fibers.


Loft is the height of the insert. The higher the loft, the fluffier the pillow.

Baffle Box

Without a baffle box design, your duvet would be very lumpy! A Baffle is a small interior wall inside a duvet that prevents the fluffy microfibers from moving around too much and keeps everything in place. The “box” refers to the box pattern that emerges when lots of baffles are sewn into a duvet insert.


Weave is what separates raw cotton (the kind you pick in a field) from the cotton products you know and love. Popular weaves include cable knit, chambray, broadcloth, canvas, chino.


Vertical yarns



Horizontal yarns

Long Staple

Long staple refers to the length of the fibers we weave to make fabric. As a rule, long-staple fibers last longer and break/pill (get scratchy) less often – they’re higher quality all around.

Thread Count

Thread count measures the number of horizontal and vertical threads (warp & weft) woven into a square inch of fabric. We don’t think thread count is a fair metric to use when talking about fabric quality. But more on that on our 40 Winks blog.
