Expert Review by Jed
The perfect size for taller sleepers, the Twin XL size Sealy Response Essentials Castra IV Firm Mattress is the first model in the Essentials collection to make use of a coil system. It is uniquely designed to provide economical comfort in addition to firm underlying support. With a rating of 2 on our Comfort Scale, the Castra is one of the most firm models available in this collection. If you're attempting to keep your cost down and want something that feels really firm, this is an excellent choice.

The Sealy Response Essentials Castra IV Firm Mattress features a woven cover with an added layer of Sealy Cushion Air Foam to provide comfort and promote good air flow. A layer of SealySupport Firm Foam helps create a solid feel, and it also enhances durability. Using individually wrapped coils, the Sealy Response Coil System contours well to the curves of your body while providing deep down support. This system is ideal if you want to rest undisturbed since it helps isolate motion if movement occurs.

In conclusion, the Twin XL size Sealy Response Essentials Castra IV Firm Mattress is a great upgrade from the previous Castra III model. It is certainly one of the better value mattresses on the market today.

Sealy Castra IV Firm
Normally, it could take me up to one-hour to fall asleep. Since I bought this mattress -- I'm asleep within 15 minutes AND I'm able to stay asleep thru the night! I highly recommend this mattress to those who enjoy a wonderful night's sleep.

Very good mattress
If you are looking for a firm mattress, this is the one. I haven’t had a backache since. It took a while to get it but it was with it. Great price too.

Great mattress at a great price.
I bought this mattress for my 8 year old daughter. We have used it for about 3 months and she sleeps well on it. I even slept one night on it and it was very comfortable. Great mattress at a great price.

Great relief from back pain
After extensive research, bought this mattress and it really worked out. Save me from back pain by keeping position flat and composed to the spine structure. Highly recommend for people with backache
