We keep the last cart check apart from current product prices, so an old code date never reads as a permanent promise. Here is what the cart showed.

Best Havnby products to use AWD on
The site’s operator owns two Havnby mattresses: the FlatCore for Model Y, $494.10 with AWD, and the FlatCore Solo for one sleeper, $359.10 with AWD. For a Model S, 3, X or Y without the Model Y floor shape, read the CloudCore review.
The code column is the list price minus 10%. Rows marked “cart-tested” were seen in a cart. The others are calculated, so check your own cart before you pay.

Every public Havnby code, tested
Coupon sites list a dozen Havnby codes. On 12 September 2026 we entered each one into a cart holding the FlatCore for Model Y on Havnby’s Norway storefront. On 16 September 2026 we ran AWD again in a US cart, with a control code.
| Code | Listed as | Cart result |
|---|---|---|
AWD | 10% (this site) | 10% on every listing tested, sale items included. $549.00 → $494.10 on 16 Sep 2026. |
CRV20 | 20% | 20% on the FlatCore CR-V only. Rejected on the FlatCore for Model Y. |

On the FlatCore for Model Y, no public code beat AWD. For the Honda CR-V FlatCore or the CloudCore Diagonal, CRV20 or DIAGONAL20 saves more on that one product.
WELCOME10 is a flat $10 and LAYFLAT a flat $20, not a percentage. We tried the other public codes on the FlatCore for Model Y only.
Why trust this code
The site’s operator, Fredrik Mastouri, owns the FlatCore for Model Y and the FlatCore Solo and shows both on the AWD Camper YouTube channel, which carries the same code. We checked AWD in real carts on 12 and 16 September 2026, and the cart rejected a made-up control code in the same session. The owner confirmed on 8 October 2026 that AWD still works.

Havnby returns, trial and warranty
From Havnby’s policy pages. We checked the return fees and shipping times on 29 September 2026. The code changes none of this.
- Sleep trial
- 60 days from delivery
- Sealed items
- Full refund
- Opened mattress, change of mind
- Can be returned, for a feeThe two policy pages disagree. The returns page lists $15 (opened) or $30 (stained). The refund policy lists $10 (light use) or $20 (visible wear). Ask Havnby in writing which fee applies before you open the mattress.
- Return shipping
- Paid by the customerTypically $20–$30 for a mattress.
- Warranty
- 3-year limited, for purchases from 1 June 20265 years for earlier orders.
- Shipping
- Free to the USA, Canada, the EU and AustraliaThe shipping policy quotes 5–7 business days, product pages 5–8. Items not stocked locally ship from Asia in 7–14 business days.
Havnby discount code questions
- Does AWD work in Europe?
- Yes. On 12 September 2026 AWD took 10% off seven listings on Havnby’s Norway storefront, and Havnby ships free to the EU. We earn a commission when you use the code.
- Can I combine it with a sale?
- Yes, with sale prices: in our carts AWD also took 10% off listings that were already reduced. We did not test two codes together. We earn a commission when you use AWD.
- Is there a better Havnby code?
- Not for a Tesla mattress. No public code beat AWD on the FlatCore for Model Y on 12 September 2026. CRV20 and DIAGONAL20 give 20% only on their own product, and WELCOME10 and LAYFLAT are flat $10 and $20 discounts.
- Is Havnby legit?
- Yes, in our experience. The site’s operator owns and has used the FlatCore for Model Y and the FlatCore Solo. Havnby offers a 60-day sleep trial and a 3-year limited warranty. It is not the clothing brand HAVN.
- What is the return policy?
- You have a 60-day sleep trial from delivery. Sealed items get a full refund. An opened mattress can be returned for a fee of $10–$30, and you pay return shipping, typically $20–$30.
