Workspace: The Right Brain Sits. The Left Brain Stands.

Susan Gregg Koger, 28, and Eric Koger, 29, are the husband-and-wife co-founders and principal owners of ModCloth, an online fashion retailer.

WHERE THEY ARE Our headquarters are in San Francisco. When I’m not traveling, I sit in a pod with my husband, Eric, and our assistants. It’s an open office. I run the creative side, and Eric runs financial.

COMFORT, PLEASE I don’t even know what kind of chair I have, but it’s very comfortable. It’s not the prettiest chair, but in the form-versus-function argument here, function wins.

DO NOT DISTURB We have a cultural norm that wearing headphones means you are not to be disturbed. If someone’s wearing headphones, send them an e-mail or G-chat. But because Eric and I are so close, we break that rule all the time.

DON’T BOX HER IN We can all see one another’s desks — and their organization or lack thereof. One thing that drives me nuts is when employees get deliveries for their homes at the office and leave stacks of empty boxes by their desks.

WHOSE KNICKKNACK? Some of the things between our desks are mine, and some are Eric’s. The piñata is mine. The robots I bought for Eric.

TCHOTCHKE PHILOSOPHY This is what I do: I find something, think it’s cool, buy it, put it up and then, when I am less inspired by it, I take it down. I go through phases.

LUNCH ROUTINE We get a delivery of something that’s hopefully high in protein. Pizza makes me want to take a nap. I try to take 30 minutes off for lunch. We have a little couch by the desk and I try to chill there.

STYLE STATEMENTS I have a big wardrobe. I’ve been buying from ModCloth for years now and we have more than 8,000 items. I dress to my mood. Generally I am feminine and quirky, and I like to mix modern with vintage.

HER LIBRARY It’s all vintage reference books. I love having that imagery around to inspire me. My National Geographic magazines are also really important. They date from between the 1930s and ’60s. There’s something incredible about the color in them.

HIM

UNDERSTATED STYLE I am the left brain of ModCloth’s operations. I am not necessarily the stylish one. I’ve got a consistent wardrobe of jeans, sneakers and either a colored shirt or a plain black V-neck. The most stylish thing about me is my large Mac monitor, which I love. It’s a beautiful display, and it makes me happy to walk up to it and do my work.

WHY HE STANDS I read that sitting and not moving for extended periods of time were bad for your health. A standing desk forces me to move around more.

MEET WITH YOUR FEET There’s a space to the left of my computers where people can stand and work, and I hold standing meetings there. You tend to reach decisions a lot faster when everyone stands.

NO WORDS I have a Pandora station of lyric-less music. My favorites include Ratatat, the Glitch Mob, Do Make Say Think and Little People. It helps me tune out the world.

THE OFFICE SHEDDER My pug, Winston, sits in my lap whenever I am in a chair, and I end up with pug fur on me. I use a lint brush to clean up. The Winston graphic is a company theme. His likeness shows up everywhere.

FLUIDITY At least once a year, we do a company hackathon, where we take a few days off, organize into teams that each tackle an idea or problem. This year, we commemorated it with a water bottle.

IN HIS OFFICE DRAWERS Files, extra headphones, basic toiletries for use if I have to rush into the office and clean up.

WHEN SHE’S AWAY My wife travels a lot more than I do. The wedding photo on my desk is a visual reminder of her.
