Frequently Asked Questions
Should I get Havnby FlatCore or CloudCore?
Choose FlatCore for deeper, Model Y-specific leveling support. Choose CloudCore for broader Tesla model coverage, a 1.13 kg lower listed weight and a price $200 below FlatCore at the 19 August 2026 check, or $150 below it at the 24 August check.
What's the main difference?
Havnby FlatCore uses a deeper shaped profile for Model Y, while Havnby CloudCore is lower, lighter and offered in selectable Model S, 3, X and Y variants.
Is Havnby FlatCore worth the higher price?
The Havnby FlatCore premium is easier to justify when Model Y slope correction and its 19 cm maximum depth matter most. Havnby CloudCore is the stronger value when lower weight, a lower profile or another Tesla model matters more.
Which is easier to set up?
Both have built-in pumps. Havnby claims roughly 80 seconds to inflate FlatCore and 70 seconds for CloudCore; these are seller figures, not our measured times.
