Frequently asked questions

What is the DA4031 seat base foam cushion and what does it do?

The DA4031 is the lower outer foam cushion for the seat base on the Land Rover Defender 90 and 110. It sits between the seat frame and the seat cover, providing the main support layer and maintaining the seat's shape and load distribution.

Where exactly does this cushion fit in the seat?

It forms the lower outer section of the seat base assembly. It installs onto the seat base structure and interfaces with the upper cushion and trim cover, so it's one part of a base built from multiple foam sections rather than the complete seat.

Does this cushion fit all Defender seats?

It's listed for the Land Rover Defender 90 and 110 lower outer seat base. Defender seat foam changed over the years and across seat types, so compare the shape of this lower outer section against your existing cushion before ordering.
