The operator, who also runs the AWD Camper YouTube channel, bought both this full-width FlatCore Model Y and the narrower FlatCore Solo. Havnby did not lend them. The channel uses the same partner code as this site, so we disclose it here. The short video of 15 July 2026 shows both mattresses in a Model Y.

What the evidence can prove
Seller listing for live verification:
This is an owner review backed by seller documents. The operator bought the FlatCore and the Solo and compared them on video on 15 July 2026 and found that two adults need the full width. Havnby’s product page, product data, warranty and return terms were checked on 19 August 2026 and re-checked on 16 and 29 September 2026; price, availability and specifications were unchanged at the last check. Havnby’s product data shows a $509 compare-at price below the $549 list price, so we report the $549 shown in the store. The store’s review count can include other vehicles, so we do not treat it as Tesla fit evidence.

Checks before you buy
FlatCore Model Y is a 193 × 132 cm foam-and-air mattress with a 7.5-inch maximum and 3.1-inch minimum profile. The checks below pair Havnby’s figures with what the operator found, and name the specs Havnby leaves out.
Packing and cargo space
Havnby lists a 5.1 kg mattress and a 67 × 43 cm stored size, with powered deflation and a bag included. It says the packed mattress fits in the frunk or cargo area, but does not publish a third bag dimension or packed volume. With the mattress in use, the operator’s gear goes under the seatbacks or in the frunk.
Fabric, foam and build quality
Havnby describes a foam-backed air structure with a soft-touch TPU surface; the varying profile counters the rise of the folded rear seats. A feature heading says “7.5-Inch Foam Support”, but 7.5 inches is the maximum product height, not a foam-layer thickness. Havnby publishes no foam density, layer thicknesses or full fabric composition.
Pump, power and setup
The built-in ABS pump runs from the car’s 12V socket: about 80 seconds to inflate and 90 to deflate, by Havnby’s figures. No separate inflator is needed, but the socket must be within reach during setup. Havnby publishes no pump pressure, cable length, power draw or manual backup.
Sleep quality and support
The 193 × 132 cm footprint is the width the operator found two adults need. The 7.5-to-3.1-inch profile levels the folded-seat slope but raises the surface near the hatch. Havnby publishes no measured final angle, insulation value or overnight air-retention figure.
Cleaning, moisture and storage
A custom sheet is included. The listing gives no cleaning procedure, fabric composition or wash temperature for the sheet or the mattress surface, so follow the label or manual that comes in the box, not the care guidance for another Havnby model.
Solo or full width: what the operator found
Watch on YouTube- Two adults need the full width. The Solo sleeps one person; the video allows for two small children at most. The video points couples to this mattress.
- Gear goes under or in the frunk. With the full-width mattress in place there is no lane beside the bed, so bags go under the seatbacks or in the front trunk; with the Solo they sit beside the sleeper.
- The operator keeps both. Solo for a solo trip with a lot of equipment, full width for two people, chosen per trip.
The operator’s first-night review of the Solo, with unboxing, inflation and delivery notes, is summarised on the FlatCore Solo page.
Strengths and tradeoffs
Why we rate it
- Owner-tested: wide enough for two adults, per the operator’s 15 July 2026 video
- Published 193 × 132 cm full-width footprint and 300 kg maximum load
- Shaped 7.5-to-3.1-inch profile made for the Model Y floor
- Built-in 12V inflation and deflation, about 80 and 90 seconds by Havnby’s figures
- 60-day sleep trial, three-year limited warranty, sheet and bag included
Tradeoffs
- The 7.5-inch maximum profile uses more cabin height than the 4.5-inch CloudCore
- At $549 it costs more than the CloudCore and the FlatCore Solo ($399 each)
- No gear lane beside the bed, and the pump needs the car’s 12V socket
- No published foam density, layer thicknesses or packed volume
Trial, warranty and care
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. The warranty covers defects only.
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. Havnby’s two policy pages disagree on the fee for opened returns: the returns page lists $15 (opened) or $30 (stained), and the refund policy lists $10 (light use) or $20 (visible wear); unopened items are $0 on both (checked 29 September 2026). Ask Havnby in writing which fee applies before you open the mattress.
Which Model Y does it fit?
Havnby sells two Model Y choices on one SKU: 2020–2024 and 2025–2026. The 2025–2026 choice covers the Juniper refresh, although the selector does not use that name. There is no Model 3, Model S, Model X or Model Y L option; for the six-seater, see the FlatCore Model Y L.
Havnby sold the FlatCore as the AutoLevel before, and the address of this page keeps the older name. Havnby’s product data dates the listing to 23 October 2025.
How the shaped profile works
The FlatCore is 19 cm (7.5 in) at its thickest point and 7.9 cm (3.1 in) at its thinnest. The varying depth is meant to cancel the rise of the folded rear seats, so the surface ends up level. It is the deepest profile among Havnby’s mattresses for the standard Model Y; the Model Y L Solo lists 7.9 inches. The cost of that depth is headroom: the lower CloudCore is 4.5 inches.

FAQ
Will it fit my 2025 Model Y Juniper?
Yes, through the 2025–2026 selection. Havnby sells separate 2020–2024 and 2025–2026 Model Y choices, but the selector does not use the word Juniper and publishes no geometry for each year range. There is no Model 3, Model S, Model X or Model Y L option on this listing.
Is it long enough for someone 190 cm tall?
Only just, on paper. Havnby lists 193 × 132 cm, 19 cm (7.5 in) at the thickest point and 7.9 cm (3.1 in) at the thinnest, and no sleeper height limit. The seller lists a 300 kg maximum load.
How heavy is it, and how does the pump work?
Havnby lists 5.1 kg and a 67 × 43 cm stored size with no third dimension. The ABS pump is built in and runs from the car’s 12V socket, about 80 seconds to inflate and 90 to deflate by Havnby’s figures. It has no rechargeable battery, and no manual backup is published.
What does it cost, and is there a discount code?
Havnby listed it at $549 on 29 September 2026, down from $599 on 19 August 2026. The partner code AWD took it from $549.00 to $494.10 before shipping and tax in a cart test on 16 September 2026. We earn a commission if you buy through our links.
What are the return and warranty terms?
Havnby offers a 60-day sleep trial from delivery and a three-year limited warranty on purchases from 1 June 2026; the warranty covers defects only. For a non-quality return you pay return shipping, and Havnby’s two policy pages list different fees for opened items, so ask in writing before you open it.
Should I buy the FlatCore or the FlatCore Solo?
The FlatCore for two people, the Solo for one sleeper with gear. The operator owns both and picks per trip; the video of 15 July 2026 concludes that two adults need this 132 cm width, while the 80 cm Solo leaves a gear lane beside the sleeper. The Solo was $399 on 29 September 2026.
