Havnby's most versatile current mattress fits listed Model S, 3, X and Y variants. At $399, its 11.5 cm foam-and-air construction is thinner than FlatCore and easier to move, but shoppers must select the exact car and year.

CloudCore is one of the three current Havnby Tesla Model Y mattress options, alongside the full-width FlatCore Foam Mattress and the FlatCore Solo Edition. Unlike those Model Y-specific products, Havnby currently offers CloudCore variants for Tesla Model S, Model 3, Model X and Model Y.
This review is based on Havnby's live product listing and published specification table. We have not conducted hands-on sleep testing. Dimensions, weight, setup times, load capacity, trial and warranty below are manufacturer figures checked on 23 July 2026.

How CloudCore differs from FlatCore
CloudCore is the range's cross-model choice. Its published 11.5 cm depth is lower than the shaped FlatCore's 19 cm maximum, while its 3.95 kg listed weight is also lower than FlatCore's 5.08 kg. That makes CloudCore more attractive when portability and broader vehicle selection matter more than the deepest Model Y-specific leveling profile.
The tradeoff is that a single published 193 × 132 cm surface does not prove identical edge fit in every Tesla cabin. Havnby asks shoppers to select a vehicle and model year, so the exact option in the cart matters. Confirm the variant rather than assuming a Model Y unit will automatically suit a Model 3, S or X.
Strengths
- Current variants listed for Model S, 3, X and Y
- Lower $399 observed price than the full-width FlatCore
- Light 3.95 kg published weight
- Built-in pump and included storage bag
- 60-day trial and three-year warranty advertised by Havnby
Tradeoffs
- Vehicle and model-year selection must be checked carefully
- Thinner than the deepest part of FlatCore
- Inflation, deflation and load figures are seller claims
- Foam-and-air construction still depends on valves and an air chamber
- Live price, stock and return conditions can change
Setup and storage
Havnby lists 70 seconds to inflate and 85 seconds to deflate. The product is supplied with the CloudCore mattress, storage bag, user manual and two eye masks. The 72 × 40 × 40 cm packed dimensions are larger than a backpacking pad, so compare them with the space you expect to keep free while driving.
The stated 300 kg capacity describes the seller's maximum load claim, not our independent measurement. Couples should also compare usable width, combined shoulder room and preferred firmness instead of treating a capacity number as proof of comfort.
Who should choose CloudCore?
CloudCore is the clearest Havnby option for a Tesla owner who wants one current product family covering several Tesla models, or a Model Y owner who wants a lower price and lower profile than FlatCore. Choose FlatCore when Model Y-specific slope correction and greater maximum depth matter more. Choose the Solo Edition when one sleeper wants a dedicated cargo lane beside the bed.
Skip CloudCore if…
- You want the deepest Model Y-specific leveling support.
- You need a one-person mattress that leaves half the cargo floor open.
- You are unwilling to verify the exact vehicle and year variant.
- You want a pure-foam mattress with no inflatable chamber.
Bottom line
CloudCore fills a genuine gap in Havnby's current lineup: it is the $399, lighter cross-model alternative, while FlatCore focuses on deeper Model Y support and FlatCore Solo focuses on one-person storage efficiency. Our 8.0/10 score is an editorial assessment of current specifications, fit breadth, value and evidence limits—not a claim of personal test nights.
