Questions and answers

Is a 6-inch mattress thick enough for adults?
It works for occasional or temporary sleeping, but most adults sleeping on it nightly will want 8 inches or more. The 500 lb weight rating covers heavier sleepers, but thickness, not load, is the limit.
How firm is it?
Milliard lists it as medium-firm: 4 inches of dense polyurethane foam with 1 inch of soft memory foam on top. Expect a supportive, fairly firm surface rather than a plush one.
Can I feel the folds when lying on it?
Some sleepers notice the seams where the three sections meet, especially on the thinner 6-inch model. A mattress topper or a thicker tri-fold reduces this.
How do I clean it?
The jacquard cover zips off and is machine washable. The foam core itself should only be spot cleaned and aired out.
Does it work on the floor or on a frame?
Both. The anti-slip bottom keeps it in place on carpet or a hard floor, and it fits most standard bed frames in Twin and Full.
When is it cheapest?
The best new price was $154.99 at Milliard as of November 7, 2026. Tri-fold mattresses often drop during back-to-school and holiday sales.
Where is the 6 Inch Tri-fold Memory Foam Mattress cheapest?
At Milliard, for $154.99, 35% under what the other stores charge, as of our latest check.
Where can I buy the 6 Inch Tri-fold Memory Foam Mattress?
3 stores we checked sell it, including Milliard, The Home Depot, eBay.
