Expert Review by Jed
An excellent option for couples, the Queen size Sealy Response Essentials Castra IV Firm Mattress is the first model in the Essentials collection to contain a coil system. It is expertly engineered to provide economical comfort plus firm underlying support. With a rating of 2 on our Comfort Scale, the Castra is one of the firmest mattresses available in this collection. If you want something that is affordable and enjoy a very firm comfort level, this is a fantastic choice.

The Sealy Response Essentials Castra IV Firm Mattress features a woven cover with an added layer of Sealy Cushion Air Foam, which provides comfort and promotes good air flow throughout the mattress. A layer of SealySupport Firm Foam ensures a solid feel, and it even enhances durability. Utilizing individually wrapped coils, the Sealy Response Coil System contours well to the unique curves of your body while delivering deep down support. This system also helps isolate motion when movement occurs, so you can rest undisturbed if your partner shifts or leaves the bed.

To summarize, the Queen size Sealy Response Essentials Castra IV Firm Mattress is an excellent update from the previous Castra III model. It is definitely one of the better value mattresses available today.
