Sleepmax Extra Firm Memory Foam Mattress Topper 3 Inch Queen Size

- 3 inch reversible, two layer
- Copper, gel, charcoal foam
- Queen size
Our take
Against the PERLECARE Firm, it lets you flip to a second firmness without buying again.
Why it made the shortlist
The Sleepmax Extra Firm is a 3 inch queen topper with a reversible two layer design, so the top side is firm and the bottom side is extra firm. The foam blends copper, gel, bamboo charcoal and green tea for cooling.
It suits sleepers who are unsure how firm they want to go.
What works
- Flip it to change firmness level
- Cooling blend of gel and bamboo charcoal
- Two layer foam spreads weight evenly
Watch out for
- Queen size, not RV short queen
