Decision summary
CloudCore is the broadest Havnby Tesla listing by model coverage and has a lower published profile than FlatCore, but Havnby warns that Model 3 and Model S can remain sloped and the pump description is internally inconsistent.
This is a secondary-research review based only on Havnby’s official product page, official product data, warranty terms and return terms checked on 19 August 2026. No hands-on fit, comfort, noise, pressure-retention or setup test was performed for this assessment. Dimensions, timings, capacity and material descriptions below are seller-published figures, not independent measurements.
At the source check, the USD storefront showed every visible Tesla year selection available at $399. The product feed records a publication date of 23 August 2024. The price is a dated observation, not a promise of today’s total; confirm the exact vehicle option and final amount before paying.
Exact Tesla fit and product identity
The live selector lists Model 3 for 2017–2026, Model Y for 2020–2026, Model X for 2015–2026 and Model S only for 2023–2026. A generic title mentioning Model S must not be expanded to earlier Model S years.
Every model and year choice uses the same seller SKU, price and 76 × 52 × 4.5-inch specification. The page does not publish a different cut or measurement for each Tesla cabin.

| Included | Mattress, storage bag, manual and two eye masks |
Construction and setup
Havnby describes CloudCore as an air-supported mattress with a 30D TPU surface and high-density foam intended to reduce the bounce and sag associated with an air-only bed. The listed total height is 4.5 inches; foam density and the split between foam and air are not given.
The specification table lists a built-in pump, 70 seconds to inflate and 85 seconds to deflate. A regional note says European orders receive a 12V DC vehicle-plug version by default and customers must request the battery-powered version at checkout.
The product page gives both a 28.3 × 15.7 × 15.7-inch storage size and a separate 18.1 × 14.6-inch compressed measurement. It does not explain the measurement conditions or why one record has three dimensions and the other two.
What the official evidence supports
The seller record clearly exposes the cross-model year menu, overall size, weight, load figure, TPU description, pump times and package contents. It also directly discloses the remaining slope concern in Model 3 and Model S.
The official record supports the following practical strengths:
- Official selector spans Model S, 3, X and Y within stated year ranges
- Lower 4.5-inch profile than the full FlatCore Model Y
- Published 3.95 kg mattress weight
- Built-in powered inflation and deflation
- Seller lists a 300 kg maximum load
What remains unknown or internally inconsistent
A trustworthy decision also requires the missing data to remain visible. The current Havnby material does not close these gaps:
- Havnby does not publish model-specific cut, width or slope compensation for S, 3, X and Y
- Havnby does not publish foam density and individual foam-layer thickness
- Havnby does not publish the exact battery-pump configuration outside the European 12V default
- Havnby does not publish which stored-size figure should be used for a reproducible packed-volume comparison
The main copy calls CloudCore battery-powered, the Europe note says 12V is the default, and a later feature paragraph uses about 80 seconds instead of the 70-second specification. These variants and timings must be attributed rather than normalised into one unqualified fact.
Documented strengths
- Official selector spans Model S, 3, X and Y within stated year ranges
- Lower 4.5-inch profile than the full FlatCore Model Y
- Published 3.95 kg mattress weight
- Built-in powered inflation and deflation
- Seller lists a 300 kg maximum load
Concrete tradeoffs
- Havnby warns that Model 3 and Model S may not become fully level
- All Tesla models and years share one SKU and one set of dimensions
- European pump hardware differs from the battery-focused product description
- The page states both 70 and approximately 80 seconds for inflation
Ownership terms, care and storage
Havnby’s current warranty page states that eligible purchases made on or after 1 June 2026 receive a three-year limited warranty for manufacturing and quality-related defects under normal use. Punctures, cuts, misuse, normal wear, unauthorised changes and second-hand purchases are excluded. That is a limited defect warranty, not a promise about personal comfort or vehicle fit.
Havnby’s return page states a 60-day sleep trial from delivery. For a non-quality return, the customer pays return shipping and original shipping charges are not refunded. The current policy also lists possible condition fees of $15 for an opened clean item and $30 when visible staining, soiling or cleaning is required. Those terms should be checked again before ordering.
Havnby identifies water-resistant TPU but does not publish a complete cleaning method, removable-cover specification or machine-wash instruction for this CloudCore listing.
Who should consider it?
Consider it when one lower-profile mattress is wanted across one of the explicitly listed Tesla model-year ranges, especially if the multi-use tent or guest-bed format matters more than vehicle-specific leveling geometry.
Who should not buy it?
Skip it when a Model 3 or Model S must become demonstrably level, when the exact pump power source must be known before checkout, or when model-specific dimensions are required.
The nearest in-site alternatives are:
- Havnby FlatCore Model Y — publishes a deeper Model Y-specific leveling profile
- Havnby FlatCore Solo — leaves a cargo lane for one-person Model Y camping
- FlatCore vs CloudCore — sets the seller-listed profile, weight, fit and pump details side by side
FAQ
Does CloudCore fit every Model S?
No. The current selector begins with Model S 2023 and runs through 2026.
Will it level a Model 3?
Havnby explicitly says the mattress may not be fully level in Model 3 or Model S because of the trunk slope.
Is the pump battery-powered?
The page is inconsistent. It describes battery power, while European orders default to a 12V vehicle-plug version unless a battery version is requested.
Are the four Tesla versions different sizes?
Havnby publishes one 76 × 52 × 4.5-inch measurement and one SKU for all visible selections.
Bottom line
CloudCore offers the broadest official Tesla selector in Havnby’s current range, but broad compatibility is not the same as model-specific leveling. The Model 3/S warning, shared SKU and pump inconsistencies should remain prominent.
Source facts were checked against the official Havnby product listing, the current warranty policy and the current return policy on 19 August 2026. Unpublished specifications remain unpublished here; seller claims are not converted into test results, scores or owner-sentiment percentages.
