I haven’t been sleeping well lately. I toss and turn and wake up repeatedly throughout the night. As a result I’m really tired most of the time. I’m starting to suspect that I need a new mattress. Yes, surprisingly, the key to a better night’s sleep could be as simple as changing your mattress. Here’s one that I’ve been coveting—the Sequin Bed from designer Vera Wang by Serta. It’s really comfortable, as I discovered when I had the chance to try it out a few weeks ago. The inner spring and latex foam construction make it both soft and supportive, while the Sensura fabric cover is luxurious, like Vera Wang’s dresses.
