EN SUITE BEDROOM SETS
You know, the sets that come with the bed, nightstand, dresser and more. Caitlin Murray of Black Lacquer Design says they just end up feeling uninspired. “You could get a much more interesting room, for a comparable price, with a couple of trips to local flea markets and thrift stores,” she says.

BAR CARTS
When done right, designer Lindsay Pennington says these pieces can be flattering and useful. But they sometimes have the same issues as open shelving: “If you’re the least bit inclined to untidiness, it’s not for you,” she warns.

HUGE ENTERTAINMENT CENTERS
Even though you can’t beat the storage in these pieces, they end up dominating the room and lack flexibility, because they’re too big to rearrange, says Kristina Leigh Wiggins, author of Building Your Home: A Simple Guide to Making Good Decisions.
