Choose the Seal U / Sealion 6 / Song Plus option for a 2024–2026 Sealion 6 DM-i. This mattress version fits over the original boot floor and folded rear seats; it is not an insert for the compartment beneath the floor.
Choose the Tang mattress only for a seven-seat vehicle with a 2+3+2 layout. Fold both rear seating rows for setup. Six-seat models with second-row captain’s chairs are excluded.
Yes, for the original ATTO 3. The ATTO 3 EVO is a separate application and is excluded. If you are unsure which version you have, send your year, make, model and VIN to support@evparts4x4.com before ordering.
The manufacturer specifies a 4.5 cm high-density foam layer, approximately 1.77 inches. Memory foam and slow-rebound properties are not specified. No inflation or air pump is needed.
Yes. Two adjustable telescopic extension boards are included to bridge the gap behind the front seats and support the extended mattress area. Position and support them before use.

Each kit includes the selected vehicle-specific mattress, two adjustable extension boards, a storage bag and a blackout eye mask. The option marked + 2 Travel Pillows also includes two travel pillows.
The original ATTO 3 packed mattress bag is approximately 68 × 50 × 40 cm and can be stored in its underfloor spare-wheel well with other items cleared as needed. Packed dimensions and underfloor storage are not confirmed for the other vehicle versions.
