Is the Lucid 6-inch mattress good for side sleepers?

It is medium firm and only 1 inch of memory foam, so side sleepers often find it too firm at the shoulder and hip. Back and stomach sleepers are the better fit.

How long does it take to expand?

Lucid says to allow 24 to 48 hours for full expansion. A warm room speeds it up, and the mattress may smell faintly until it airs out.

Does it work in a bunk bed or RV?

Yes. The 6-inch height is the point: it fits bunk beds, trundles and RV bunks where a standard 10- to 12-inch mattress won't.

What is the warranty?

Lucid offers a 10-year limited warranty, and the foam is CertiPUR-US certified for emissions and content.

Is $139.99 a good price for the queen?

That is the best new price across 3 stores as of November 4, 2026. For a 6-inch queen memory foam mattress it is a low entry price, so it is a fair buy at that figure.
