Quick Summary (TL;DR)
The Havnby Foam is a versatile, budget-friendly option that works in both Tesla Model Y and Model 3. The 4.5-inch foam won't match the comfort of thicker mattresses, but it's a solid choice for occasional campers who want Havnby quality without the premium price. The versatility makes it ideal for households with multiple Tesla models or those planning to upgrade.

The Versatility Advantage
The Havnby Foam's main selling point is its ability to fit both the Tesla Model Y and Model 3. This might seem like a small detail, but it has real practical benefits:
Multi-Tesla Households
If your household has both a Model Y and Model 3, one mattress works for both. No need to buy two separate mattresses.
Planning to Upgrade
If you currently own a Model 3 but plan to upgrade to a Model Y in the future, your mattress investment carries over.
Rental or Borrowed Teslas
For those who occasionally rent Teslas or borrow family/friend vehicles, one mattress covers both popular models.
Resale Value
If you sell your mattress later, it appeals to a wider buyer pool since it works with both vehicles.
Comfort Reality Check: 4.5" vs 7.5"
Let's be direct: the 4.5-inch foam won't feel as luxurious as the 7.5-inch Havnby Autolevel. Here's what to expect:
| Factor | Havnby Foam (4.5") | Havnby Autolevel (7.5") |
|---|---|---|
| Feel the Car Floor? | Sometimes (heavier sleepers) | Rarely |
| Side Sleeper Support | Adequate | Excellent |
| Multi-Night Trips | Acceptable | Comfortable |
| Best For | Occasional campers | Frequent campers |
Our take: If you camp in your Tesla more than 5-6 times per year, invest in the thicker Havnby Autolevel. For occasional trips, the Foam delivers decent comfort at a lower price point.
What Real Owners Say
Here's feedback from verified Havnby Foam owners:
"I did a ton of research on Reddit and YouTube to find the best Tesla camping mattress. This is hands down the best Tesla mattress I've tried. Unlike my regular air mattresses, this one has memory foam, completely changing the comfort level."
— Amazon reviewer, March 2025
"It truly feels like sleeping on a regular mattress rather than an inflatable one. The built-in foam structure gives it great support that pure air mattresses just can't match."
— Verified buyer
"We used to have a 2021 Model Y and used a thick foam mattress. The Havnby feels more comfortable and takes up less space. The 60-second inflation is a game changer."
— Multi-Tesla owner
"If you are buying a mattress for your Tesla Y, spend the extra money and buy this Havnby Air+Foam mattress. This is as comfortable as my mattress at home."
— Trustpilot review
Common themes: Owners consistently praise the hybrid air+foam design as superior to pure air mattresses. The 60-second inflation and compact storage are frequently mentioned positives.
Setup Guide: Hotel Comfort in 60 Seconds
The Havnby Foam features one of the fastest setup times of any Tesla mattress thanks to its integrated pump.
- Fold down the rear seats - Pull the release levers to fold the Model Y's 60/40 split seats or Model 3's rear seats flat.
- Remove the mattress from its storage bag - At 22 lbs (10 kg), it's manageable but not ultralight.
- Position and unfold - Place the mattress in the cargo area with the pump toward the back.
- Press the inflate button - The integrated 6000Pa pump inflates the mattress in approximately 60 seconds. The upgraded durable pump motor is designed for extended use cycles.
- Adjust firmness - Add more air for firmer support, or release some air for a softer feel. Everyone's preference is different.
- Enable Camp Mode - Turn on Tesla's Camp Mode for climate control throughout the night.
Packing Up
Deflation takes about 50 seconds with the pump. The mattress compresses into its storage bag and fits in the Model Y frunk or Model 3 sub-trunk. The TPU waterproof material wipes clean easily before storage.

Frequently Asked Questions
Does the Havnby Foam work in both Model Y and Model 3?
Yes, the Havnby Foam is designed to fit both Tesla Model Y and Model 3. The mattress dimensions and shape accommodate both vehicles' interior layouts, making it a versatile choice for households with multiple Tesla models.
How thick is the Havnby Foam compared to the Autolevel?
The Havnby Foam is 4.5 inches thick, compared to the Autolevel's 7.5 inches. While thinner, the Foam still provides decent comfort for occasional camping and is more compact for storage.
Is the Havnby Foam comfortable for heavier sleepers?
The Havnby Foam supports up to 660 lbs (300kg), but heavier sleepers may feel the car floor more due to the thinner 4.5-inch foam. For sleepers over 200 lbs who camp frequently, we recommend the thicker Havnby Autolevel (7.5 inches).
What's included with the Havnby Foam mattress?
The Havnby Foam comes with the mattress, a USB-C rechargeable pump for inflation/deflation, a storage bag, and 2 eye masks. The 5-year warranty is also included.
Is the Havnby Foam waterproof?
Yes, the Havnby Foam uses eco-safe TPU material that's fully waterproof and pet-friendly. It's easy to wipe clean after camping trips and resistant to muddy paws.
How fast does the Havnby Foam inflate?
The included USB-C pump inflates the mattress in approximately 60 seconds. The same pump deflates for easy packing. It recharges quickly from your Tesla's USB ports.
Does the Havnby Foam have the auto-level feature?
The Foam version has basic slope compensation, but the premium auto-leveling foam filler design is exclusive to the Havnby Autolevel model. If level sleeping is critical for you, upgrade to the Autolevel for $100 more.
Can two adults sleep comfortably on the Havnby Foam?
Yes, the 76" x 52" dimensions accommodate two adults. However, with 4.5 inches of foam, couples may prefer the thicker 7.5-inch Autolevel for added comfort, especially for side sleepers.
Does the AWD discount code work for the Foam?
Yes, code AWD provides 10% off all Havnby products including the Foam, Autolevel, and Solo versions. This saves approximately $26 on the Foam mattress.

The Bottom Line
The Havnby Foam is a practical choice for Tesla owners who value versatility over maximum comfort. Its ability to fit both Model Y and Model 3 makes it unique in the market, and Havnby's build quality and 5-year warranty provide confidence in the purchase.
At $259, it sits comfortably between budget options and high-end mattresses. The 4.5-inch foam won't feel like a real bed, but it's absolutely adequate for occasional camping trips. If you own or plan to own both a Model Y and Model 3, this is the only mattress that serves both.
For frequent campers who prioritize comfort, step up to the Havnby Autolevel with its thicker 7.5-inch foam. But for occasional use with the flexibility of dual-vehicle compatibility, the Foam delivers solid value.
