Heymat X Sight Unseen Doormat
Iconic furniture silhouettes collapse into one bold organic outline, in three palettes: Emerald, Lilac and Peach.
Jill Singer and Monica Khemsurov of Sight Unseen designed the mat for Heymat's Iconic Women Collection, folding several recognizable furniture profiles into one continuous organic shape. Emerald pairs deep indigo with emerald green, Lilac sets lilac against olive green, and Peach runs lemon yellow and deep indigo through peach. The surface is 100% nylon over a 100% nitrile rubber backing, 0.3 in thick and produced in Poland. Browse the rest of the Heymat collection.

Common Questions
Can the mat be machine washed at home?
Yes. Heymat specifies 140°F (60°C) with bleach-free detergent, then tumble or flat drying. Both sizes fit a standard home machine, and Heymat suggests two to four washes a year.
Which size should I choose?
23 x 32 in suits a standard single front door and comes in Emerald or Lilac; 32 x 48 in is scaled for double doors, wide entries or a hallway landing and comes in Emerald or Peach.
Is it made from recycled material like other Heymat mats?
No. The Sight Unseen mats use a 100% nylon surface on a 100% nitrile rubber backing, unlike Heymat's recycled-PET mats such as Dis and Mix.
