Nowadays deeper sofas are a popular choice for less formal spaces like den/family/TV rooms. The extra depth is more conducive to lounging, especially if two people want to lay across the sofa at the same time! Also, a nice deep sofa can make a great extra bed. If sleeping is a major consideration, then focus on styles with a single seat cushion and make sure they're long enough.
Here are a few examples of sofas with deep seats...

|Belgian Shelter Arm Slipcovered Sofa - Restoration Hardware|
|Greyson Sofa - BoBo Intriguing Objects|
|Piazza Velvet Storm Sofa - CB2|
|Bliss Sofa - West Elm|
|The Theodore Sofa - Jayson Home and Garden|
|Silhouettes Sofa with Dressmaker Skirt - Hickory Chair|
|Tufted Deep Sofa in Sand Velvet - RoomService|
If you're considering a sofa with a deep seat for a casual room in your house, just be sure that there are plenty of other more upright seating options in the area. The addition of a pair of armchairs or a more traditional sofa will not only accommodate guests, it can also keep the room from looking sloppy and overly lax. Choosing a structured sofa style (like the tufted ones above) will also keep the space looking orderly and put-together.
What do you think of deep-seated sofas? Do you have one in your home? Do they annoy you? I really like them but they annoy my husband which is one of the reasons why the one in our den isn't super deep!
