Serta vs. Sealy Mattress Overview
The Serta and Sealy mattresses have some key similarities but also some stark differences. As far as similarities, the two beds both have a soft memory foam feel, and they both come in at around the same price. Here are the big differences:
- Construction — The Serta iComfort is an all-foam bed, while the Sealy Posturepedic is a hybrid with both coils and foam.
- Support — While both beds have a soft memory foam feel, the Sealy bed provides more support, and you won’t feel like you’re sinking in too much.
To help you further investigate which mattress is right for you, we’ve put together a video comparison looking at the Serta and Sealy mattresses.
Design & Construction
Let’s start by breaking down the construction of each bed. The Serta iComfort is a 13” mattress made entirely of foam. The bed has three layers:
- Support foam — At the bottom of the Serta mattress is a foam base for support.
- Memory foam — In the center of the bed is a layer of thick EverCool Supreme Memory Foam.
- Gel foam — The top layer of the Serta mattress is an inch of TempActiv Mad Gel Memory Foam.
Unlike The Serta mattress, the Sealy Posturepedic is a hybrid mattress with a combination of both coils and foam. It also has three distinct layers:
- Base layer — The bottom layer of the Sealy is a foundation of support coils, most of which are concentrated in the center.
- Transition layer — To help transition from the coils to the softer coil, the bed has a layer of soft foam.
- Comfort layer — The top layer of the mattress is made of pressure-relieving foam.
Feel & Firmness
Both the Serta and Sealy mattresses have a soft memory foam feel. In the case of the Serta, you sink into it to the point of feeling a bit stuck. You have the option of two different firmness levels: plush and cushion firm. The plush bed is around a medium on the firmness scale, while the cushion firm is closer to a medium-firm to firm.
The Sealy also has a memory foam feel, but you don’t get stuck in it the same way you do in the Serta. It contours to your body without being overwhelming. The coil layer helps provide some extra support. This bed falls around a medium on the firmness scale.
Other Factors to Consider
The firmness and construction are important, but they aren’t the only factors to consider when choosing the right mattress. Especially for couples, there are a few other factors to look at.
The Serta and Sealy mattresses are fairly evenly matched when it comes to edge support, but Sealy Posturepedic probably takes the cake because of its hybrid construction.
We were impressed with the motion isolation of both the Serta and Sealy mattresses. Since both are primarily memory foam, they deaden movement well. If your partner tends to toss and turn throughout the night, we don’t think you will be disturbed.
We’d say both of these beds are temperature neutral. They won’t heat you up during the night, but they also won’t help to keep you cool.
Body Type Analysis
Certain beds are better suited to people of specific body types, so it’s important to consider that when shopping for a new mattress.
Petite individuals will probably sleep most comfortably on the plush version of the Serta mattress. The Sealy mattress and the firm Serta mattress are both likely to be too firm, especially for those who sleep on their side.
Average-sized individuals could be happy with either the Serta or Sealy mattress. In this case, it really comes down to whether you prefer a hybrid or all-foam mattress. Keep in mind, hybrid beds offer up more support if you suffer from back pain, or sleep on your back and stomach.
Heavy individuals may not find that they get enough support from the Serta mattress since it’s made entirely of foam. If you do prefer foam, you should opt for the firm model. The Sealy, on the other hand, is a great option for heavier folks. The coils within the bed help to provide plenty of support.
Sleeper Type Analysis
In addition to your body type, it’s important to consider your sleeping style when choosing the right mattress for you.
- Side Sleepers
Both the Serta and Sealy mattress could be a good choice for side sleepers. If you choose the Serta bed, you’ll probably be most comfortable on the plush model since it will provide better pressure relief for your shoulders and hips.
- Combo Sleepers
Combo sleepers can be comfortable on either mattress. But if you move around a lot during the night, you’ll likely be more comfortable on the Sealy bed. The coils will provide enough bounce for you to easily adjust positions throughout the night, while the Serta’s foam will create some resistance.
- Back & Stomach Sleepers
If you are a back or stomach sleeper, you may be happy with either option, with some caveats. First, the Sealy mattress isn’t great for back and stomach sleepers who are over 250 pounds. And back and stomach sleepers opting for the Serta bed will likely be more comfortable on the firm model.
