Well, the provided web links are playing coy, teasing us with titles about sofa depth but sharing none of the actual juicy details. So, let's dive into this cushy topic using general knowledge.
Asking how deep a sofa cushion is can mean one of two things, and the answer depends entirely on whether you're measuring for a polite perch or a full-on lounging abyss.
Most often, people are talking about the "seat depth," which is the crucial measurement from the very front of the seat cushion to the back cushion. This determines how you sit. A standard, well-behaved sofa will offer you about 21 to 24 inches of depth. This is perfect for sitting upright, having conversations, and not losing the TV remote in the couch's nether-regions.
Then you have the deep-seated sofas, the champions of napping and movie marathons. These can plunge you into a luxurious 28 to 35 inches of pure, unadulterated comfort, giving you plenty of room to curl up with your feet.
If, however, you meant the actual thickness of the cushion itself—its vertical "poof," if you will—that typically ranges from 4 to 8 inches. But remember, a thicker cushion doesn't always mean a comfier one; it's the magical stuff inside that truly counts.
