Bottom Line

The Serta Castleview is an exclusive Perfect Sleeper mattress that effectively provides temperature control, lumbar support, pressure relief, motion isolation, and edge support. The 739 Custom Support individually wrapped coils provide individualized support, while memory foam layers provide body cradling comfort.

Get the Serta Castleview if...

  • You like sleeping cool. If you like sleeping cool, this mattress is a great choice. The Castleview's cool-to-the-touch cover creates a comfortably cool sensation, plus its Cool Twist gel memory foam pulls excess heat away from your body to keep you cool while you sleep.
  • You're a restless sleeper. The Serta Castleview's gel memory foam provides cradling comfort, encouraging you to relax into this mattress instead of tossing and turning. Its foam encasement provides excellent edge support just in case you do move.
  • You sleep on your back. The combination of body conforming memory foam layers and individually wrapped coils encourage proper spinal alignment and provide optimal lumbar support, which is great if you sleep on your back.

Skip the Serta Castleview if...

  • You need more firmness options. The Serta Castleview is only available in Cushion Firm, which isn't suitable if you like particularly plush or firm mattresses. If you need additional firmness options, the Castleview isn't a great choice.
  • A sleep trial is important to you. Serta doesn't promise a sleep trial with the Castleview model, so unless your third-party retailer provides one, you'll have to be sure about your purchase. If this sounds like a risk you'd rather not take, skip the Serta Castleview.


  • Cool Twist cooling gel memory foam
  • 739 Custom Support individually wrapped coils
  • Exceptional pressure relief
  • Great for back support


  • No guaranteed sleep trial
  • Can't buy online from Serta


The Serta Castleview has a cushion firm firmness level, which is ideal for all sleep styles, including back and stomach sleepers. Cushion firm provides the cushioning you crave with the support you need for healthy spine alignment. This is also the most popular comfort level of all Saatva mattresses.

Construction & Design

  • CoolFeel Cover: The Serta Castleview features a CoolFeel cover made of cool-to-the-touch fabric which creates a pleasantly cool sensation.
  • Cool Twist Gel Memory Foam: Serta's exclusive Cool Twist gel memory foam uses  delivers cool, contouring pressure relief by dissipating excess heat and adapting to your body's unique shape and size.
  • 739 Custom Support Coil System: The Castleview's 739 Custom Support coil system provides exceptional lumbar support while reducing motion transfer across the bed for a night of more supportive and sound sleep. Individually wrapped coils react to every contour of your body for custom, personalized support.
  • Total Edge Foam Encasement: The Total Edge foam encasement reduces roll-off and increases usable surface area.

Support & Motion Isolation

This mattress features 739 individually wrapped coils and premium layers of body-conforming gel memory foam, making it great choice for motion isolation. The individually wrapped coils provide targeted, isolated support and reduces motion transfer across the bed. Plus, the gel memory foam layer absorbs impact from sudden movements, allowing you to sleep soundly. It's an excellent choice for couples!

The Serta Castleview also performs well at edge support. The border of this mattress is encased in high density foam which reinforces its edges. This means that you can use more surface area, and potential roll-off and sagging are greatly reduced.

Reasons to Buy the Serta Castleview

  1. You share your bed with someone. If you need superior motion isolation, the Serta Castleview is a great choice. Individually wrapped coils provide isolated support, while memory foam layers absorb energy created by movements. Both you and your partner will be able to sleep undisturbed.
  2. Buying US-made products is important to you. The Serta Castleview is manufactured entirely in the US like every other Serta product. Serta has designed and manufactured all of their products in the US for almost 90 years!
  3. You need deep pressure relief. If you need relief in common pressure point areas like hips, shoulders, and your lower back, the Serta Castleview is an excellent choice. Each wrapped coil supports your unique shape while memory foam layers provide cradling, body conforming comfort.

Reasons to Avoid the Serta Castleview

  1. You're looking for a simple purchasing experience. Unfortunately, the Serta Castleview has to be bought through a third-party retailer. Third-party retailers can complicate shipping, sleep trials, returns, and even warranties, which might make your purchase more stressful than it should be. If you'd rather purchase your mattress online directly from the original retailer, the Serta Castleview isn't a great choice.

The Serta Castleview is an ideal choice if you want lumbar support and pressure relief at an affordable price. You can get the Serta Castleview for a great price, today!
