Haven has a presence in a room that Hampton doesn't: higher arms at 27.25 inches, a fuller back at 35.5 inches, and a 42.25-inch depth that gives the sofa a generous, settled quality. At 84.75 inches wide it's compact for a king sofa frame, which is a useful combination: a substantial-looking piece that still fits in tighter floor plans.
The Hybrid Deluxe mechanism opens in a single step: one lift, and the back auto-folds flat. No dragging a frame out, no removing a seat cushion, and only the loose back cushions need to come off first. That one-step conversion is the meaningful difference between Haven and Hampton; it's faster and more intuitive for a guest who hasn't done it before. The bed deploys out from the wall; plan 88.5 inches of floor depth.
The king bed runs 76 inches wide by 80 inches long. Five-inch built-in mattress of cold-cured, high-density HR foam, CertiPUR certified. Daily Sleeper rated. Seat depth at 23.5 inches is notably deeper than most sleeper sofas in this size range, which makes the everyday lounging experience more comfortable than the bed specs alone suggest.
Frame is solid spruce with mortise-and-tenon joinery and birch plywood, FSC and PEFC certified, made in the EU. Over 100 fabrics and over 100 leathers available. Four to six weeks from order.
Haven king is for the household where nightly or frequent guest use is realistic and you want the mechanism to be simple enough that anyone can operate it without a walkthrough. Cross-shop against Hampton King Sofa if you prefer a lower-profile track-arm look and the two-step Hybrid conversion is fine; Hampton comes in about 1.75 inches shallower in seat depth. Choose Haven if the deeper seat and one-step open are worth the slightly fuller silhouette.
