Turn the Sienna Into a Family Basecamp
Havnby FlatCore for Toyota Sienna is shaped to turn the minivan's long cabin into a flatter, more supportive sleep space. Its structured air base helps bridge floor transitions, while the 7.5-inch air-and-foam surface adds the cushioning families, road-trippers, and weekend campers need for a more restorative night.
- Sienna-specific support: Designed around the Toyota Sienna's long interior layout.
- Floor-transition leveling: Helps smooth the slopes and height changes that make generic mattresses feel uneven.
- 7.5-inch air-and-foam comfort: Combines structured support with thick foam cushioning for a steadier sleep surface.
- Built-in rechargeable pump: Inflates in about 60 seconds and deflates in about 70 seconds without a separate pump.
- Family-trip storage: Packs into the included carry bag when the cabin needs to carry passengers or gear again.
- No permanent platform required: Adds a supported sleep surface without committing the van to a full-time camper build.

FAQ
Is FlatCore made specifically for the Toyota Sienna?
Yes. FlatCore is shaped for a prepared Toyota Sienna cabin. Confirm your model year and seating layout against the fit guide before ordering.
How does FlatCore make the sleep surface flatter?
The shaped air base adds support where the prepared cabin floor changes height, helping compensate for transitions that a generic mattress simply follows.
How long does setup take?
The built-in rechargeable pump inflates the mattress in about 60 seconds and powers deflation in about 70 seconds.
How does shipping work?
Havnby ships from warehouses in California, New Jersey, Sydney, Toronto, and Frankfurt. Most in-stock products ship free to the contiguous U.S., most of Canada, Australia, New Zealand, and Europe in 5-8 business days. Hawaii, Alaska, and items not stocked locally ship from Asia in 7-14 business days and may require a shipping fee.
How does the 60-day sleep trial work?
Most new Havnby mattresses include a 60-day sleep trial from delivery. Return eligibility, shipping costs, and condition requirements follow the current Havnby return policy.
