Comfort Scale Rating

The Sealy Response Santa Paula IV Cushion Firm mattress is a firm-feeling mattress and we rate it 4 on our 10 point Comfort Scale (a 1 is hard, 10 is softest). This level of comfort is good for those who like a firmer mattress, but it's not too firm, so it'll work for a lot of people.

Pressure Test Results

We pressure tested the Santa Paula IV mattress with small/petite, average and big/large body size people on their sides and on their back sleeping positions to measure the support and comfort.

The Santa Paula IV Cushion Firm tested well especially for back sleepers where we rated those sleeper positions a very solid ‘Recommend’. For side sleepers, it was a mixed bag. In that case, what's most important is your preference. If you like a firm bed, you'll feel comfortable on it. There's just more pressure on the shoulders and hips for those that didn't see a 'Recommended' score. This Santa Paula IV bed gives good support, shown in our testing. I'd say that's probably because it has a supportive coil system enhanced by the SealyCool Gel Foam in the center third of the mattress.

Conclusion

The Sealy Response Performance Santa Paula IV Cushion Firm mattress is an affordable option for a firm bed. We ‘Recommend’ the mattress for back sleepers with mixed ratings for side sleepers, based on our pressure tests. This bed is a good option for back-sleepers who like a medium-firm bed. There's added support for the lower back with the SealyCool Gel Foam in the center third.

Decent pressure relief comes from the high-quality foams Sealy used, they work really well to make it comfortable for back sleepers. The edge support is a nice addition, it makes the entire surface more sleepable (especially good for those with sleep partners), adds to the durability, and makes it easier to sit on the edge without feeling like you'll slip off. This bed is durable and will last for years. It has a lot of positive customer reviews, and will likely be very comfortable and supportive for you
