Latitude Run Memory Foam Mattress for Sofa

Our take on the Latitude Run Memory Foam Mattress for Sofa

This is a 4-inch memory foam replacement mattress sized for sofa beds, sold in Queen and Full and 72 inches long. The thin profile is meant to fold or roll into a sleeper frame, not to stand alone as a regular bed. At $119.99 at Wayfair as of November 4, 2026, it is the only new price listed, so there is no recent range to compare against — treat that figure as the current benchmark rather than a discount.

Questions and answers

Is a 4-inch mattress thick enough for a sofa bed?

It is enough to soften a sleeper frame for occasional guests. For nightly sleeping or heavier adults, a 5- to 6-inch sofa bed mattress gives more support.

Will it fit my sleeper sofa?

It comes in Full and Queen at 72 inches long, which matches most standard sleeper frames. Measure your frame's interior before ordering, since some sofas use odd sizes.

Can I use it on the floor or a platform bed?

You can, but 4 inches of foam offers little support on a hard surface. It is designed to sit inside a sofa bed frame.

Is $119.99 a good price?

It is the only new price listed, at Wayfair as of November 4, 2026, so there is no recent low to beat. Comparable 4-inch sofa bed foam mattresses often run $100 to $200.

Does memory foam sleep hot?

Yes, memory foam traps heat more than innerspring or hybrid designs. A breathable mattress pad and a cooler room help.

Where is the Latitude Run Memory Foam Mattress for Sofa cheapest?

At Wayfair, for $119.99, as of our latest check.
