GoodBed Expert Review
Our Take on Beautyrest Harmony Lux Coral Island Extra Firm
Michael Magnuson
Founder of GoodBed, Leading Mattress Expert
BEST if you
- Want a very firm mattress
- Are mainly a stomach sleeper (though this mattress can also be very good for back sleepers)
- Regularly sit or sleep along the edge of your bed (edge support is excellent)
- Have a clear preference for sleeping 'on' your mattress rather than 'in' it
- Prefer a below average amount of 'memory feel'
NOT IDEAL if you
- Are a side sleeper, especially if you weigh less than 150 lb
- Don't like much bounce in your mattress
- Can be easily disturbed by other movements in the bed (though motion isolation is still OK)
- Prefer some softness in your mattress

Yes, the Beautyrest Harmony Lux Coral Island Extra Firm mattress is adjustable base compatible. This means it is designed to be used on an adjustable base without incurring damage or voiding the warranty. In our review of this mattress, we tested it on an adjustable base to look for any adverse effects as the head and foot are elevated, and to see how well it conforms to the contours of the base both with and without the weight of a sleeper. Overall, we found the Coral Island Extra Firm to have good adjustable base compatibility.
