Sleep on a real mattress. Not on your couch.

Who is the Origine mattress for?

The Origine mattress, at least 13 cm thick with a density of 40 kg/m³, offers a dynamic feel while providing firm support, ideal for back support. It is suitable for most sleepers and for daily use.

What does 40 kg/m³ foam density mean?

Density refers to the amount of material contained in one cubic meter of foam. The higher the density, the denser, stronger, and more durable the foam is. It directly affects the perceived firmness and longevity of the mattress.

Is it possible to get this model with a different mattress?

Yes, you can choose a different mattress comfort level for this sofa bed. La Maison Convertible offers four different mattresses, which you can try out in-store. The Pure, Symphonie, and Elytis mattresses are other models that offer different levels of comfort and support compared to the Origine. Whether you prefer pocket-coil or memory foam technology, our selection has something for everyone.

Firm comfort
Often preferred for daily sleeping

Is a slatted bed base suitable for daily use?

A wooden slatted base offers a firmer sleeping comfort than a mesh base. Additionally, the separation in the middle of the base reduces the movements of the other sleeper, thus providing better sleep independence.
A slatted base is recommended for a daily-use sofa bed. It offers:

Firmer lumbar support, beneficial for sleep
Better ventilation under the mattress, which extends its lifespan
More stable support under repeated load every night.

The majority of our models designed for daily sleeping are equipped with slatted or mixed bases.

Is a slatted bed base more durable?

The high-quality slats that make up our bed bases prevent the gradual sagging of the mattress by maintaining better ventilation and ensure a more even distribution of pressure even with daily use.

Is it possible to get this model with a different type of bed base?

This sofa bed is available with a slatted base. In-store, try this more accessible base, which also offers greater flexibility.
