The Internet has changed the way mattress shopping works, and there have been many new companies hit the scene. While this opens up options, it can make it difficult for people with less common sleep needs to find what they’re looking for since newer companies are trying to appeal to a broad audience as they enter the market.

Sealy has been in the business since 1889, thus allowing them more than enough time to try out different approaches when it comes to firmness. If you’re looking for something more on the plush end, this could be a good pick. Keep reading to see how it worked out for me.

The Good

  • Works well for most sleep positions
  • Company has a good reputation
  • White glove delivery convenient

Layer-by-Layer Breakdown

I could spend all day telling you how I thought this product felt, but it’s much more helpful to explain how it works. To do this, we’ll be taking a look inside this product to see what it’s made of, one layer at a time.

This is a great example of a hybrid mattress. By using a combination of materials, it works to balance the pros and cons of each to arrive at a product specially-designed to cater to specific needs and preferences.

Comfort Zone

The comfort zone is a total of three inches thick, and this is the area that offers cushioning and padding to buffer the support system. It starts off with two inches of SealyCushion Extra Soft Foam. This offers the feeling of envelopment that you typically expect with a plusher mattress. It also works to offer deep pressure relief and keep tossing and turning minimal.

The next inch is comprised of SealySupport Firm Foam. While this may sound like it would counter Sealy’s goal to produce a final product that offers a plush feel, this layer is less thick, located further from the sleep surface, and offers the foundational element to help transition into support.

Support Zone

The comfort section is followed by Sealy’s Corrective Back Support System. It focuses on distributing and stabilizing body weight as well as spinal alignment and consists mostly of the Sealy Response Coil System. Designed to balance support and comfort, it features an exclusive design that works to offer great contour. This is achieved through the use of individually-wrapped coils.

Aside from contour, the coils also help keep motion transfer low. This is because motion is largely isolated to the point of impact since the coils work independently of one another. I think sleep partners who like a plush to medium-plush feel will appreciate these features. The support area ends with an inch of SealySupport firm foam.

The Cover

The cover is made of mid-loft, soft knit fabric, and much of the plush feel comes from the durable spun yarns. It also contains FlameGuard AirLoft Fiber that minimizes fire risks. The final product is very soft against your skin.

The cover is quilted, and this includes two inches of Sealy Cushion Air Foam and a half inch of SealyCool Gel Foam. Both work to help the mattress breathe well, and this is good to incorporate so closely to the sleep surface since this is the closest to your body heat.

Furthermore, the Posturepedic Technology layer provides support through center third consideration that adds support to the hip area, thus improving durability expectations where the most wear and tear is known to take place both vertically and horizontally.

Our Full Santa Paula IV Plush Review

You’re living in a unique day and age when it comes to mattress shopping. If you’re new to the experience, consider this… we used to have to load up in a truck, drive from one store to another, get hassled by pushy salesmen, and make a final choice under pressure and without the ease in ability to fact check.

The ability to shop online opens up new and exciting possibilities. Your mattress is delivered to your home, and you can shop across the country without ever leaving your home. Since you can’t feel it for yourself, though, that’s where we step in. I’ve had the chance to try this mattress out for myself, and just some of the aspects we’ll cover based on my experience include:

  •        Firmness
  •        Comfort
  •        Pain Relief & Support
  •        Heat Retention (how cool the mattress remains)
  •        Off Gassing (the odor the mattress emits)
  •        Intimacy


The firmness of this product is very clearly stated in the name, but let’s talk about how plush it really is. We can get an idea by looking at the coil gauge. Gauges range from 12 to 15 with the higher number indicating a plusher product. The Santa Paula IV Cushion Plush mattress has a coil gauge of 14.

I’ve tried several different plush products, and this one is more on the medium plush end of the spectrum. If you’re looking for something really plush, you may be a little disappointed. However, I think it could be perfect for sleep partners who have different preferences as the slighter plushness could make for a more accommodating compromise. If you need just a bit more plushness, you can always consider the purchase of a mattress topper.


A plusher sleep surface makes it easier for people who don’t weigh much to engage with the mattress layers. It can also help offer the additional contour side sleepers need to accommodate the hips and shoulders as these are common pressure points. I think you’ll appreciate the fact that, although it is more on the plush end of the firmness spectrum, there is still ample bounce, making it easy to move around.

If you sleep on your stomach, you may find the mattress to sink in a bit too much. This can make it hard to breathe. If this is the case, we also tried out the Santa Paula firm option. It may be more effective in offering the feel you need.

Support and Pain Relief

The coil unit does an excellent job offering support. This can be difficult to balance when the overall aim is a plush sleep surface, and I think Sealy did a good job in this regard.

The edge support offered is excellent, especially if you’re used to sleeping on a product made entirely of foam. If you sleep close to the edge or sit on it often, I think you’ll be happy with the support you get. It’s facilitated by the inclusion of the SolidEdge HD Foam Encasement. This helps extend your sleep surface and aid in mobility.

Heat Transfer Capability

If you sleep hot, this product did an excellent job at transferring heat, but this didn’t come as a big surprise. This is because there are multiple considerations made to keep this product sleeping cool. These include:

  • Coil units breathe well naturally
  • Egg carton-style Air Foam navigates good airflow
  • Gel foam designed specifically with heat transfer in mind


Volatile organic compounds are just a part of the manufacturing process. The slight chemical smell you experience with new products is inevitable, but some give off more smell than others.

In the case of the Santa Paula IV plush mattress, offgassing was very minimal, and I think this has a lot to do with the fact that your mattress is delivered without being vacuum-sealed and stored in a box right after production. If offgassing bothers you, I think you’ll be happy with what you get and be able to use your mattress immediately without any issues.


A plush mattress can sometimes cause issues when it comes to intimacy. This is because, if you sink into the layers too much, it can limit mobility. I think Sealy did a good job balancing plushness and bounce. The coil unit helps add the bounce you need to minimize your efforts, but the layers work to add comfort.

Best Sleeping Positions on Santa Paula IV Plush

It’s critical that you consider your preferred sleep position as you shop. Whether you have a specific position that puts you to sleep or tend to toss and turn a bit before you’re able to settle in, let’s take a look at what you can expect with the three primary sleep positions on the Sealy Posturepedic Santa Paula IV plush.

  • Side
    • A common complaint shared by side sleepers is that the hips and shoulders tend to sink into the sleep surface and cause pressure points. This makes a plusher mattress preferable in many cases. A plusher product is typically more accommodating, and the comfort layers combined with the quilted cover make the Santa Paula Plush mattress a good consideration.  
      • Side Sleeping Score: 9.0 / 10
  • Back
  • Stomach
    • If you sleep on your stomach, you really don’t want to sink in too much. This can make it difficult to breathe. While the firmness of this mattress isn’t significantly plush, if you carry a lot of weight, you may find stomach sleeping to be a bit uncomfortable.  
      • Stomach Sleeping Score: 8.0 / 10

Bed Frame Compatibility

In the excitement of shopping for a new mattress, make sure you don’t overlook the right base. Although you can put it on the floor, this increases the chances of the development of mold and fungus, thus compromising the durability of your mattress. As you prepare for the arrival of your mattress, a few options you can consider include:

  • Box springs
  • Slatted base
  • Firm platform base
  • Adjustable base

If you want to use an adjustable base with a coil unit mattress, it can be hard to find one that’s compatible, so this could make the Santa Paula line a good option.

Warranty, Guarantee, and Trial Period

  •        Warranty: 10 years non-prorated
  •        Guarantee: Money back guarantee for any manufacturing-related issues.
  •        Trial Period: 120 night trial period


I was very impressed with how well this product did at sleeping cool, and I think its overall firmness setting and support make it a good fit for sleep partners looking to accommodate varied preferences. Despite its use of an innerspring unit, motion transfer was low, and the excellent edge support helped me transition in and out of bed with ease.

If you’re a stomach sleeper who carries a lot of weight, I think you may want to try something firmer to facilitate your needs, but it was very accommodating for side sleeping with its great contour.

Is the Sealy Posturepedic Response Performance Santa Paula IV Plush for You?

It’s easy to see there are many components to consider as you shop for your next mattress, so let’s cut to the chase. The Santa Paula IV plush may be for you if:

  • You sleep on your side
  • You sleep hot
  • You and your sleep partner are looking for a firmness that can cater to varied firmness preferences
  • You like bounce without excessive motion transfer
  • You have limited mobility
  • You don’t want to deal with unboxing a mattress
  • You want to work with a company that’s well-established in the industry
