8 Most Comfortable California King Size Mattresses — That Is What Happiness Feels Like

The WinkBed is a premium product. It does have a hefty price, but once you learn more about its features, you’ll be convinced it’s a solid investment.

The WinkBed has quite a few layers. They include pocket coils for supreme support. However, if you’re worried about pocket coils, don’t be as there are plenty other layers for added comfort. There are two layers of PCF polyfoam, in different thicknesses. This material will mold to your body, cradling every vertebrae in your back for ultimate support. There are also micro coils that are encased in foam pockets.

With the WinkBed, you can choose from soft, luxury firm, firmer, and plus. The first three of these options include a cotton lumbar pad for further back support.

Covering these many layers is a cover made out of TENCEL material. This material allows you to sleep cool, thanks to its immense breathability format. Even in the hottest months of summer, you will stay cool and comfortable. However, some do find that this mattress is a bit too cold in winter months, so you might want to invest in some flannel sheets to warm you up.

One final, amazing aspect of the WinkBed is that it comes with a lifetime warranty. That’s right; you can make this investment and know that if there are any issues, the company will help you out. Furthermore, there is a 120-night trial available.

What we liked:

• Includes a lifetime guarantee and 120-night trial

Get ready for a restful night of sleep. If you’re constantly tossing and turning, then a new mattress can help you get ready for the next day ahead of you. The Brooklyn Sedona is a hybrid type of mattress that uses both coils and foams to get you the sleep you deserve.

Inside this mattress are multiple layers that all work together for amazing results. While there is a layer of coils, they are individually encased and won’t be poking into you. There are then a further three layers of foam, all with individual properties that work together to support you.

There is a layer of hyper-dense memory foam for amazing, solid support.

Then, there is another layer of gel-infused memory foam. The gel helps to keep you cool by promoting air flow. If you’ve ever woken up in a state of sweat, you know how important it is to keep cool at night.

Finally, there is another layer of comfort foam. This cradles your entire body, ensuring there are no pressure points on your back and spine. You don’t want to wake up feeling like your body sore, and this layer will prevent that feeling.

The Brooklyn Sedona comes with a nice, 10-year limited warranty. While good, it isn’t as good as some other models. 10 years should be fine, but there are other products on this list that come with lifetime guarantees, so it is something to think about.

However, the Brooklyn Sedona does have a 120-night trial period, which is quite nice.

What we liked:

• Multiple layers of memory foam for extra support
• Coils are all individually encased
• Includes a 120-night trial period

What could be better:

The Nolah Signature Mattress is an all-foam product that is made to fully support you while you’re busy in dreamland.

This mattress is actually quite unique in that you can flip the mattress, depending on how firm you want it to be. Most foam mattresses do not have the ability to be flipped. With the Nolah, however, not only can it be flipped, but it encourages you to do so.

Many people purchase mattresses without really knowing how firm they want them to be. You might have an idea of what works for you, but it can take months before realizing that it’s just not working. With the Nolah Signature Mattress, you get a medium-soft side and a medium-firm side. You can try out the side you think will work best, and if you’re not quite getting the sleep you want, you can simply flip the mattress and try out the other side.

This takes away the whole issue of having to return a mattress and purchase a new one, which is very inconvenient.

To produce the different firmness levels, the Nolah Signature Mattress has one side with 2.5 inches of polyfoam and one side with 1 inch of polyfoam. In between are 7 inches of base foam which gives enough support for either side.

Unfortunately, the Nolah Signature Mattress is a bit pricey. However, it does offer you a way to save a bit of money. While your purchase comes with a 120-night trial, you can opt out of this feature and save money off the total price. It’s a bit of a risk, but the two different sides means you’re more likely to enjoy this mattress.

What we liked:

• Two sides of firmness to choose from
• Easy to try and decide if you like it
• Includes lifetime warranty

What could be better:

• Pricey, although there is a way to save a bit of money
