Our take on the Beautyrest Black Series Three Extra Firm Twin XL Mattress

The Beautyrest Black Series Three Extra Firm is a 14.25-inch hybrid mattress in Twin XL, built on pocket springs with a tight top and three support zones. It is the firmest option in the Black Series Three line and is adjustable-base compatible. It suits back and stomach sleepers who want a very hard surface, and its zoned coils and breathable coil layer set it apart from all-foam rivals at the same firmness.

Questions and answers

Is the Extra Firm too hard for side sleepers?
Most side sleepers will find it too hard and may wake with shoulder or hip pressure. It suits back and stomach sleepers better.
Does it work with an adjustable base?
Yes. Beautyrest lists it as adjustable-base compatible, and the pocket-spring build bends with the base.
What is the difference from the Black Series Three Firm?
This is the firmest version in the line, with less cushioning over the coils. Choose the Firm if you want some give.
What sheets fit a 14.25-inch Twin XL mattress?
Use deep-pocket Twin XL sheets rated for mattresses around 15 inches. Standard pockets may pull off the corners.
Is the Extra Firm worth it over a cheaper firm hybrid?
It adds zoned pocket coils, a temperature-regulating cover and a tight-top build that cheaper firm hybrids often skip. The trade-off is a very hard feel and a heavy mattress to rotate.
Where is the Beautyrest Black Series Three Extra Firm Twin XL Mattress cheapest?
At eBay, for $1,595.00, 44% under what the other stores charge, as of our latest check.
