The Serta iComfort Blue 100 Gentle Firm is true to its name. It has an initial soft feel but you will soon be supported by the firm base layer which prevents you from sinking in all that much. What I like about this mattress is that it is a great choice for people looking for a foam mattress with good support. It’s also available to try out in stores so you will know exactly how it feels and is priced competitively. This mattress comes with a 120 trial where you can return it within that time for a refund if not happy.

Overview of the Serta iComfort Blue 100

Here’s a brief overview of the mattress and some of its main features.

Ordering Your iComfort Mattress.

You can order this mattress directly through the Serta website. This assures that you will get the best price and will be dealing directly with the manufacturer if you have any issues. Plus you get the 120 day trial period as well.

This mattress does not come in a box. After you place your order a delivery company will contact you to arrange a time to bring it in your house and set it up. Since the mattress isn’t compressed, it will be ready to sleep on right away. I didn’t notice much off-gassing with this mattress either because it has had time to breathe.

My Serta iComfort Findings

This mattress is certainly a firm mattress but the top layer is nice and soft. You will sink just a little into this mattress before you are supported by the base layer underneath. Here’s a picture illustrating sinkage on the mattress.

Here’s another photo illustrating sinkage from the top of the mattress.

serta icomfort blue sinkageHere’s a video showing how much motion transfer you can expect on the mattress. You really don’t get any and you will also notice that the ball doesn’t bounce that much because you will hit the firmer base layer to absorb the energy.

This video shows you the inside of the mattress and how each layer works. You’ll notice that the top layer provides really good pressure relief but you won’t sink into this mattress that much which is good for people seeking a firmer feel.

My Serta iComfort Recommendation

What sets this mattress apart from the competition is that Serta has been able to create a mattress with a soft top layer and firm base layer to create a unique feel. With most firm mattresses you get very little contouring. Here you quickly sink into the mattress about an inch then are instantly supported by the base layer. This mattress could be used by side sleepers but I think back and especially stomach sleepers will appreciate the support in the lower back.

Since there are no springs, you won’t be dealing with any motion transfer issues and although it is all foam and will sleep a little warm, you won’t sink in as much as a softer mattress so that shouldn’t be as big of an issue. I also think this would make a great mattress for heavier people who need the support a traditional mattress may not provide.
