Pillow top vs. euro top

Which comfort layer is best for you

  • Close up image of a pillow top mattress

    Pillow top

    A pillow top is an additional layer of padding sewn into the top of your mattress. This provides a softer sleeping surface while still offering breathability and support from the mattress below.


    Pillow tops create a puffy, pillow-like appearance. The padding might be regular foam, memory foam, latex, fiberfill, cotton or wool, depending on the mattress.

  • Close up of a Serta Classic mattress with a euro top.

    Euro top

    A euro top mattress has layers of foam or padding added to the top, but the padding extends to the edge of the bed. The difference between a euro top and a pillow top is mostly visual.


    A euro top’s padding doesn’t have seams or appear puffy; it all looks like one mattress.

FAQs

What is Zoned Support?

Zoned comfort brings comfort where it matters most. The 800 unit coil support system offers three support zones with targeted support for your lower back and hips and cradled comfort everywhere else. To create the right comforts, plush models feature a slightly plusher coil and medium and firm models feature a firmer coil. 

Does this mattress sleep cool?

The Serta Classic has a breathable cover that allows the sleeper’s body heat to dissipate, keeping the surface from holding heat. The Dorian - Plush Euro Top, and all Brecon models also contain Cool Twist Gel which promotes additional airflow and heat dissipation. 

How thick are the Serta Classic models?

The Serta Classic models will vary in height from 11.5" to 14.5" depending on the comfort model. All models are considered to be standard size, and you can use standard size sheets with these mattresses.

Can the Serta Classic be flipped? 

No, the Serta Classic mattresses were not intended to be flipped. These mattresses have a dedicated top and bottom so flipping them is not required or recommended.

Really soft instead of medium firmness

The two mattresses that I purchased were supposed to be medium firmness but they are really soft. I'm unhappy about that but it would be too much hassle to return them. A. Irwin

Love our new Serta Classic Mattress!

Very happy with our Serta Classic Mattress! We are value conscious and appreciated the price $699 for a king! Not only recommended by Consumer Reports, but listed as a best value. We ordered it from Serta. It arrived promptly. Medium firmness. It is just right for us. We have noticed that the firmness and support is just right for us. So nice to have a new mattress. Conformity and motion control is spot on. We think it will be durable a well.

As advertised

Purchased Serta Alden Twin Mattress and twin boxsprings. The purchase was difficult to register with Serta. The mattress is comfortable and delivery was on time as promised.

Barbara A551

Customers overwhelmingly praise the mattress for exceptional comfort and support, with most reporting deeper sleep and relief from back, neck, and shoulder pain. The balanced medium-firm feel combines plush softness with targeted support, helping sleepers wake refreshed without aches. Many describe improved spinal alignment and reduced pressure points. Reviewers consistently note the mattress feels well-made and substantial. A few report minor durability concerns like sagging or firmness preferences, but these are vastly outweighed by widespread satisfaction with sleep quality and pain relief.
