French Mattress Sofa Guide: What They Are, How They Work & Why Designers Love Them

Questions about our beloved French mattress–style sofas? We’ve got answers. Here are some of the most frequently asked questions.

How do the mattress layers work?
The design is built in three layers: two sturdy base cushions, plus a decorative overlay mattress on top. That top layer is where clients have the most fun—choosing a contrasting or seasonal fabric for a fresh, personalized look. Some even keep multiple toppers, like changing a throw blanket. Families and pet owners especially love the practicality: the topper can be swapped out, spot-cleaned, or dry-cleaned as needed. It’s comfort, function, and style in one.

What sizes do the sofas come in?
The sofas are made to order—literally priced by the linear cm—so you can order them at any length to fit your home. The slipcover is fully removable, making it easy to update colors or fabrics over time.

If I order one, how long will it take to arrive?
Each Endless Nights Sofa is custom made in France. Production takes about 3 months, plus another 3 months for shipping. Because we import twice a year, lead time is typically 6–8 months*. As the only North American retailer, we believe these one-of-a-kind pieces are worth the wait.
*Our cut-off time to receive your sofa on our next container is September 15th!
