GoodBed Expert Review
Our Take on Serta Perfect Sleeper X Quilted Hybrid Level 1 Excelled Extra Firm

Founder of GoodBed, Leading Mattress Expert
- 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
- Can sometimes be disturbed by other movements in the bed (motion isolation is very good)
- Prefer a slightly below average amount of 'memory feel'
- Like a little bounce in your mattress, but not much
- Are a side sleeper, especially if you weigh less than 150 lb
- May use this mattress on an adjustable base (adjustable base compatibility isn't the best, but is still pretty good)
- Prefer some softness in your mattress
- Want a natural or organic mattress (though this mattress is still OK in terms of avoiding harmful chemicals)

Yes, the Serta Perfect Sleeper X Quilted Hybrid Level 1 Excelled 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 Excelled Extra Firm to have pretty good adjustable base compatibility.
