The product you buy today is the FlatCore Hybrid Support Mattress for Tesla Model Y, $549, and our review of it sits at the address we gave the AutoLevel in February 2026. Official Havnby photograph of the FlatCore Model Y, the current name of the mattress reviewers called the AutoLevel. ## The myth: two different mattresses People searching for “havnby autolevel foam mattress” in 2026 land on a store that sells no product by that name, and conclude the AutoLevel was discontinued. It was renamed. Havnby now groups its levelling mattresses under FlatCore, its flat foam mattresses under CloudCore, its back-seat pads under SnugNest and its third-row pads under MiniNest, and the old AutoLevel name survives only in one SKU code and outside the store. ## Where the AutoLevel name still appears - Owner reviews on Reddit: a 2025 thread titled “Havnby Autolevel Mattress Review & Giveaway” on [r/TeslaCamping](https://www.reddit.com/r/TeslaCamping/comments/1p6lsls/) and a matching post on [r/ModelY](https://www.reddit.com/r/ModelY/comments/1p5t7hp/) describe the mattress as designed to eliminate the slope left by folded rear seats without extra pads. - Havnby’s own SKUs: the FlatCore for Toyota Sienna is sold under SKU H-ALFM-Sienna in the 16 September 2026 catalog, where ALFM reads as AutoLevel Foam Mattress. - This site: our FlatCore Model Y review was published in February 2026 at /reviews/havnby-autolevel and keeps that address so old links and searches still arrive at the right product. ## What the FlatCore is today The [FlatCore Hybrid Support Mattress for Tesla Model Y](/reviews/havnby-autolevel) ([official listing](https://havnby.com/products/flatcore-hybrid-support-mattress-for-tesla-model-y)) is a 193 × 132 cm foam-and-air mattress with a profile that Havnby lists at 7.5 inches at the thickest point and 3.1 inches at the thinnest, a built-in 12V pump, separate selections for Model Y 2020–2024 and 2025–2026, and a $549 price on 16 September 2026 (down from $599 on 19 August 2026). The levelling idea is unchanged: the thick end sits over the folded seatbacks, the thin end over the trunk floor. Havnby does not publish foam density or the thickness of each layer, and it does not publish what, if anything, changed in the foam between the AutoLevel era and the FlatCore era. ## Products that were never AutoLevel CloudCore is a different product, not a renamed one: a flatter 4.5-inch foam-and-air mattress for Model S, 3, X and Y at $399 that Havnby itself says may stay sloped in a Model 3 or Model S. If an old review praised the AutoLevel for fixing the slope, the modern equivalent is FlatCore, not CloudCore; [FlatCore vs CloudCore](/vs/havnby-flatcore-vs-cloudcore) sets out the difference. The one-person [FlatCore Solo](/reviews/havnby-solo) ($399) and the [FlatCore Model Y L](/reviews/havnby-flatcore-model-y-l) ($699) are later additions to the same family. ## Buying the right one On havnby.com choose the FlatCore listing that names your car, then the model-year variant.
