Best 5-inch Dunlop latex mattress toppers

Start with the Stumptown Organic Dunlop Latex Mattress Topper — it's the only true Dunlop latex topper I found, and Dunlop is the denser, more supportive pour, so it holds up best under a heavy sleeper or a sagging mattress.

Who the others suit:

• PlushBeds Organic Latex Topper — GOLS-certified Dunlop with a removable GOTS cotton cover; the pick if you want a certified-organic build and a washable cover.
• Latex Mattress Factory Dunlop Topper — a firm, straightforward Dunlop slab for people who want a hard, no-frills lift.
• Turmerry 7-Zone Organic Latex Topper — zoned medium feel, good if you want pressure relief at shoulders and hips rather than all-over firmness.
• Brooklyn Bedding 3" Latex Topper — a softer, more cushioning latex layer for side sleepers.

One caveat: none of these is a full 5 inches thick — the deepest latex toppers I found are around 3 inches, which is the practical limit for latex before it gets heavy and hard to move. If you truly need 5 inches of lift, a latex topper stacked over a firm foam base is the usual route.
