Our take on the Lucid 6-Inch

The Lucid 6-Inch is a low-profile gel memory foam mattress with a 2-inch plush comfort layer over a 4-inch high-density support base. It is built for bunk beds, RV bunks, sofa beds and small rooms where a standard 10-inch mattress sits too high. The firm feel suits back and stomach sleepers and lighter adults more than heavy side sleepers. At $139.99 for a queen at Amazon as of November 4, 2026, it sits at the low end of its recent range, and four stores list it new.

Pros
  • Low 6-inch profile fits bunks, RV bunks and sofa beds
  • Gel memory foam top layer sleeps cooler than plain memory foam
  • CertiPUR-US certified foam
  • 10-year warranty
  • Queen at $139.99 at Amazon as of November 4, 2026 is a low price for the size
Cons
  • Only 6 inches total, so support runs thin for heavier adults
  • Firm feel is a poor match for side sleepers who want cushioning
  • Two layers means less durability than thicker multi-layer foam beds
  • Polyester blend cover is basic
  • No edge support

Questions and answers

Is the Lucid 6-Inch worth it?
Yes if you need a low mattress for a bunk, RV or guest bed and want to spend little. It is not a good pick as a primary mattress for a heavy adult or a side sleeper who needs cushioning.
How firm is it?
It is firm. The 2-inch gel memory foam layer softens the surface a little, but the 4-inch support base dominates the feel.
Will it fit a bunk bed or RV?
A 6-inch height clears most bunk rails and RV bunk frames that a 10-inch mattress would not. Check your frame's rail height and weight limit first.
Does it work on a sofa bed?
Yes. The low profile and queen size suit standard sofa bed frames, and the foam folds away with the frame.
How long until it expands?
It ships compressed and rolled. Most of the expansion happens within a day, but give it up to 48 to 72 hours to reach full height.
When is it cheapest?
The queen was $139.99 at Amazon as of November 4, 2026, near the bottom of its recent range. Watch for mattress sales around holidays for similar or lower prices.
Where is the Lucid 6-Inch cheapest?
At Amazon, for $139.99, 38% under what the other stores charge, as of our latest check.
What do buyers say about the Lucid 6-Inch?
Rated 4.4 out of 5 from 19 ratings.
Where can I buy the Lucid 6-Inch?
