Cost Effective Comfort

by Jed Harrington

If you are looking to keep your costs low while still getting a solid mattress, this would be a good choice. This mattress scores a 2 on our comfort scale rating, meaning that it is very firm. Without all the bells and whistles of a higher end mattress, the Sealy Crown Jewel Basic Aquamarine will give you what you need from a mattress - support with a bit of comfort.

Firm Feel

With such a firm mattress, we would recommend this mainly for back or stomach sleepers as those sleeping positions can do well with less contouring. The 1 inch of Sealy Comfort Foam puts a bit of contouring between you and the dense foam core, but still while maintaining that overall very firm feel.

Foam Core

The core of this mattress is composed of a thick dense foam to provide back support. The fact that this is an all foam mattress means that it will have some motion reduction from person to person as well as be adjustable base compatible.

Bedtime without breaking the bank

All in all, the Aquamarine is a good option to go with if you are looking for a mattress to get you through the night without spending a fortune.
