Marguerite basks in the late-afternoon sun on an 18th-century rolled-arm loveseat, another family antique. The bedroom is shielded from electromagnetic fields, and a kill switch turns off all electricity in the room when the couple sleeps. n addition, the all-natural mattress is free of fire-retardant chemicals; linens are organic fibers. The antique, four-poster bed is fitted with a new headboard that expands it to queen size. Above, a colorful painting from Haiti depicts a local fruit market.
