# Havnby CloudCore Hybrid Support Mattress for Tesla Model S/3/X/Y Review

CloudCore Tesla: a 193 × 132 × 11.5 cm foam-and-air mattress sold through Model S, 3, X and Y selectors. Evidence is limited to official Havnby material checked 19 August 2026; no score or hands-on result is assigned.

Primary sources checked

## What the evidence can prove: Secondary research — no score assigned

Seller listing for live verification: August 19, 2026

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 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. Havnby does not publish model-specific cut, width or slope compensation for S, 3, X and Y The official store’s review count, where present, may span vehicle variants and is not treated as Tesla-specific fit evidence.

Quick take **Secondary research — no score assigned**

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. Havnby listed it at $399 when checked 19 August 2026. Havnby does not publish model-specific cut, width or slope compensation for S, 3, X and Y

Practical ownership review

## Six checks before you buy

a 193 × 132 × 11.5 cm foam-and-air mattress sold through Model S, 3, X and Y selectors 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 record separates those published facts from fit, comfort and durability outcomes that have not been independently established.

1. 01 **Packing and cargo space** 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. Havnby does not publish a clear method connecting its storage-size and compressed-size figures or model-specific packed placement.
2. 02 **Fabric, foam and build quality** 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. Havnby does not publish foam density, foam thickness, seam construction or a full material stack.
3. 03 **Pump, power and setup** 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. Havnby does not publish a single consistent pump configuration across regions, battery capacity or 12V power draw.
4. 04 **Sleep quality and support** The seller lists a 193 × 132 cm surface and 11.5 cm height for all four Tesla families. The same page warns that the sedan/hatch floor geometry in Model 3 and Model S can leave a slope. Havnby does not publish final sleeping angles by Tesla model, an insulation value, motion-transfer data or overnight air-retention measurements.
5. 05 **Cleaning, moisture and storage** Havnby identifies water-resistant TPU but does not publish a complete cleaning method, removable-cover specification or machine-wash instruction for this CloudCore listing. Care guidance from another Havnby model should not be transferred to this product unless the delivered label or manual says so.
6. 06 **What remains unresolved** 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

## 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.

## 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.

- [FlatCore vs CloudCore](/vs/havnby-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](https://havnby.com/products/cloudcore-hybrid-support-mattress-for-tesla-model-s-3-x-y), the [current warranty policy](https://havnby.com/pages/warranty) and the [current return policy](https://havnby.com/pages/returns-policy) on 19 August 2026.
