Our take on the Beautyrest Black Series1 X-Firm Full Mattress

The Beautyrest Black Series1 X-Firm is a 13.5-inch full-size memory foam mattress with a tight top and a gel foam layer, built for sleepers who want the firmest surface in the Black lineup. It is adjustable-base compatible and ships with a 6-inch low-profile base. The latest best price sits near the low end of its recent range, so it is a reasonable time to buy if extra-firm support is what you want.

Questions and answers

Is the Beautyrest Black Series1 X-Firm worth it?
If you want one of the firmest memory foam mattresses available and sleep mostly on your back or stomach, it is a solid pick. Side sleepers and anyone who likes cushioning should look at a softer model.
How does it compare with the Series2 or Series3?
Higher series add more foam layers and, in some models, coil support, which softens the feel and improves airflow. The Series1 X-Firm is the simplest and firmest option in the Black line.
Does it sleep hot?
The gel foam layer helps, but it is still a memory foam mattress and retains more heat than a hybrid. A breathable mattress protector and a cooler room help.
Will it work on an adjustable base?
Yes. Beautyrest lists it as adjustable-base compatible, and it ships with a 6-inch low-profile base.
What size is the full?
A full measures 54 by 75 inches, which suits one adult or a small guest room. Two adults will find it tight.
When is it cheapest?
Beautyrest mattresses typically drop during holiday sales and mattress-event periods. The current best price is already near the low end of its recent range, so waiting may not save much.
