We recently got a chance to check out a store that's been on our list since reading about it on Apartment Therapy: OC Modern. We had such a great experience all around that we just can't say enough nice things about them.
Joshua and his wife Laurie operate OC Modern out of their Long Beach home, using their ranch style house as the showroom. The house is packed with mid century modern finds at some pretty good prices. Some of the items might be gently used, and they prefer to leave things as is, but that means that you aren't paying for a piece that's had to be totally overhauled.
They offer free delivery and honestly couldn't be nicer. Check out their website for the full inventory (which they update often) or call them to schedule an appointment: 714.580.8645
