- Weigh 225 lb or more, especially if you sleep on your side or stomach
- Would worry about being able to move or rotate a very heavy mattress

Yes, the Serta iComfort Pro Level 3 Canterbury Plush 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 Canterbury Plush to have very good adjustable base compatibility.
