Havnby Foam Review (2026): Best Budget Tesla Mattress for Both Model Y and 3

What this mattress is for

The Havnby Foam is the entry-tier of Havnby's Tesla camping line. I bought it specifically to compare with the more expensive Autolevel and to see whether $269 buys real Tesla-camping comfort or just a pad. After 14 nights between November 2025 and March 2026 in Norway and Sweden, the answer is: it does, with a clear caveat. The 4.5 cm foam depth means side sleepers feel the seat seams; back sleepers don't.

Specifications and what you get

The honest assessment after 14 nights

The Havnby Foam delivers what it promises: a budget-tier pure-foam Tesla mattress that fits the rear sleeping zone correctly. The shape matches both Model Y and 3 (different SKUs), the foam is silent, and the 5-year warranty is the same as Havnby's premium products. What you give up is thickness.

At 4.5 cm, side sleepers feel hip pressure within 90 minutes and need to roll over more often than on the 10 cm Snuuzu or 19 cm Havnby Autolevel. I logged this specifically — on the same -3°C night in Beitostølen, I rolled over 8 times on the Havnby Foam vs 3 times on the Autolevel. For solo back sleepers in summer, this matters very little; for couples or anyone with hip issues, the thickness becomes an annoyance.

Cold weather performance was solid. Pure foam at 4.5 cm still beats air mattresses for thermal — I measured 1.5°C warmer surface temperature vs a generic air mattress at the same conditions. The Snuuzu's thicker foam is warmer still, but the Havnby Foam holds its own at sub-zero.

Pros and cons

Where it fits in the lineup

Best for: occasional summer campers

The Havnby Foam shines for solo back sleepers who camp 1-5 nights per year in mild weather. At $242 with the AWD code, it's the cheapest "real" Tesla mattress that works long-term. For comparison, $139 TESMAT Solo and $30 generic air mattresses fail at different things — the Havnby Foam is the value floor I'd actually buy.

Where to buy

Order from Havnby's official site with code AWD for 10% off. Make sure to select the correct version (Model Y vs Model 3) — they're different dimensions despite the shared product line. As of April 2026, AWD is verified active.

Long-term performance after 14 nights

By night 14 of testing the Havnby Foam (March 2026), the 4.5 cm foam showed measurable compression at the highest-pressure points (hip and shoulder areas for side sleepers). I measured 4.0 cm vs the original 4.5 cm at these spots — within Havnby's warranty threshold but visible. For back sleepers, compression was distributed more evenly and reached 4.2 cm uniformly. Tesla Motors Club Havnby Foam threads have owners 100+ nights in reporting similar localized compression patterns.

For occasional campers (1-10 nights/year), this compression accumulates slowly enough that the mattress will perform like-new for 5+ years. For heavy campers (50+ nights/year), expect to want a thicker option within 2-3 years. The 5-year Havnby warranty covers compression beyond 1 cm — useful if you're a heavy camper.

Why fitting both Model Y and Model 3 matters

The Havnby Foam ships in two SKUs (Y and 3 versions) but uses similar construction philosophy. For households with both Tesla models — increasingly common in 2026 as Model Y adoption matures — having compatible mattresses across vehicles is convenient. We tested the Model 3 version briefly during a partner's trip and the construction quality matches the Model Y version. Fit accuracy is good across both vehicles.

Setup, storage, and the carry experience

The Havnby Foam rolls up for storage — a meaningful advantage over pure foam alternatives like the Snuuzu which require flat storage. The included nylon carry strap holds the rolled mattress in a 30 cm diameter cylinder that fits in a small closet or backpack. For Tesla owners who don't want camping gear permanently in their trunk, this storage flexibility matters.

Setup time from rolled-up to ready-to-sleep is about 90 seconds. Faster than any pump mattress, slightly slower than the Snuuzu Model Y's just-unfold approach. An r/TeslaModelY discussion on quick-setup Tesla mattresses consistently rates the Havnby Foam in the top tier of speed.

Compromise points worth understanding

The Havnby Foam at $269 ($242 with AWD) is positioned as the budget pure-foam option in the Havnby lineup. The 4.5 cm depth is the deliberate compromise that keeps the price down. Buyers should understand: this isn't a thin version of premium mattresses — it's a different category designed for occasional comfort rather than premium daily use.

Comparing to the closest alternatives: the Havnby Autolevel at $360 ($324 with AWD) gives you 4× the foam depth and self-leveling for $82 more. The TESMAT Solo Y at $139 gives you a thinner mattress at half the price. The Havnby Foam sits in a meaningful gap that some buyers should hit, others should skip.

Side sleepers specifically: when to step up

I logged 6 of 14 nights as a side sleeper on the Havnby Foam. The pattern was consistent: easy to fall asleep, but waking 1-2 times by 3-4 AM with hip pressure. For a side sleeper camping 1-3 nights per year, the wakeups are tolerable. For 10+ nights per year as a side sleeper, the Autolevel's 19 cm depth eliminates this issue. See our side-sleeper-specific Tesla mattress ranking for context.

The verified-buyer reality

Across Havnby's verified review section and Trustpilot listings, the Havnby Foam consistently scores 4.4-4.6/5 — solid but not exceptional. The most common complaint is exactly what my testing found: thinness for side sleepers. The most common compliment is exactly what budget-conscious back sleepers report: excellent value for the price tier.

Sustainability and end-of-life considerations

Pure foam mattresses like the Havnby Foam are recyclable through specialized programs. Many Tesla camping mattress brands including Havnby will accept return shipments of end-of-life products for recycling — check with their support team. The Lyocell-style fabric tops on premium foam mattresses are also compostable in industrial facilities, though most consumers won't access these. For environmentally-conscious Tesla campers, choosing mattresses with end-of-life programs matters as much as construction quality. Sleep Foundation has guidance on mattress recycling applicable broadly. Havnby's customer service can advise on regional recycling options if you reach end-of-life with a unit.
