Those who enjoy a Soft feel can flip Layla to its white and grey side, while customers who prefer a Firm feeling can rest on the darker colored side. Both dark and light sides foster a slow response and steady contour that only memory foam can provide.

The Firm side allows customers to slowly fall into a gentle cradle, while the Soft end envelops them in a deep hug.

Brooklyn Aurora – Cooling

Highlights:

  • CertiPUR-US® Certified
  • 120-Day Trial
  • 10-Year Warranty

But is it really? The Aurora’s cover uses a tech called phase-change thermo knitting. This fabric’s temperature adapts to the surrounding area, keeping it several degrees cooler than the room. Topping off the first layer is a copper gel Energex™ foam with embedded TitanCool™, a gel designed to conduct heat towards the edges of the bed and away from the sleeper.

This hybrid incorporates a mix of memory and proprietary foams topped over a system of pocket coils that add quite a bit of bounce. Customers can choose from three firmness options: Soft, Medium, or Firm.

WinkBeds Plus – Heavy Folks

Highlights:

  • CertiPUR-US® Certified
  • 120-Day Trial
  • “Any Reason” Guarantee
  • Lifetime Warranty
  • Made in the USA

WinkBed was a forerunner on the online bedding market. Their brand has successfully cut down cost by cutting out old school mattress sales men by selling directly to customers.

WinkBed covers a large portion of this market with their plus-sized model. This bed uses a durable coil system and a thoughtful design that targets stability for heavier folks.

Most beds should support heavier sleepers for a few days or even two or three months, but the difficulty arises when heavier individuals sleep in a mattress like this for an extended amount of time. Many beds may begin to show wear and might eventually sag.

When shoppers order a WinkBed Plus, they can be confident knowing that they are ordering a bed made for them. To prove it, WinkBed covers their product with a Lifetime Warranty.

Buyer's Guide for Purchasing a King Size

Benefits of This Size

A King mattress is the size that most sleepers hope to get to at some point. If you are reading this article, hopefully, this means your King sized bed is just beyond the horizon.

A King mattress is a great transition for people used to sleeping on Queen that find that they now need some extra room. This size provides sufficient surface area for two sleepers to stretch and spread out, so hopefully no more sleeping on the edge.  If sleepers have kids or fluffy friends hopping in and out of bed, the surface area of a King can give everyone the space they need.

In addition to this, a King offers distance between sleepers, a feature that not only provides more room but also helps to dampen motion when one partner experiences a restless night’s sleep. If you co-sleep, this dimension facilitates cuddling but also leaves plenty of room to spread out when cuddle time ends. If cuddle time leads to something else, a King size can be ideal for night time activities.

This size is also great for heavier and taller individuals who literally need more space to distribute their weight and stretch out.

King and California King Differences

A King mattress is going to be wider while a California King is going to be slightly longer. Both have the same overall surface area. Here are the key differences between the King and California King:

A King mattress is 76” x 80”. This is the most common size and the dimension is good for most couples and people who just need some extra space along the edge of the bed. This is 16 inches wider than a standard Queen mattress and the same length as a Queen. (Read more about King versus Queen.)

A California King is 72” x 84”. This model often works for taller individuals who need some extra foot room. The California King takes 4 inches from the width and adds that to the length. This would be 12 inches wider than a standard Queen and 4 inches longer.

Both of these can be split into a form of split King, though it is more commonly found in the standard King sized model.

The Split King

For those with sleeping partners, it is likely that you both do not love the same exact feel of a bed. The Split King is a very common option for folks who co-sleep. What this provides is two halves of the bed, each with its own unique feel.

Maybe you like a soft mattress, while your partner prefers a firmer sleeping surface. Unlike your old sleeping arrangement, you don’t need need to compromise with a medium feel, the Split King can give both partners their perfect firmness.

This setup can be done in a few different ways. Often times a Split King setup will be two Twin XL mattresses lined up side by side. These work great with an adjustable base, as the sleepers not only get the feel they want but they can also set up the base in their preferred position.

Some companies will make a bed that splits at the head and leave the foot of the bed together. These types of beds can typically only be used with adjustable bases where only the head of the bed adjusts.

California Kings do come in split options, though these may be harder to find than a split, standard King mattress.

Top Shopping Considerations

Material Type

Beds come in all shapes, sizes, and makes. The material that sleepers choose to sleep on is going to drastically affect how they rest.

The most common materials are coils, polyfoams, memory foams, and latex. Many beds today use a mix of all of these in their construction. Here is a quick breakdown of what you might see.

Coils: Most coil mattresses these days don’t use the same type of springs your grandma and grandpa grew up on. Many bed-in-a-box brands use a pocket coil that keeps the bounce while isolating motion. These are typically part of a hybrid and topped with some sort of foam.

Foams: There are a lot of different types of foams out there, but the two most common are memory foam and polyfoam. Memory foams are going to be slow responding and contour tightly to curves to relieve pressure. Where polyfoams will have more of a quick response that helps wipe away strain.

Latex: Latex is a type of rubber foam. There are typically two types – Talalay and Dunlop latex. These differ in construction but have a very similar feel and quick responsiveness, gently contouring to sleepers bodies and cradling their curves.

Preferred Sleeping Position

What position the shopper sleeps in should determine what type of bed they want to order. The following are the four most common sleeping positions: back sleeper, side sleeper, stomach sleeper, and combinations sleeper.

Side sleepers typically like a soft bed that can relieve pressure from their hips and shoulders, as these areas put more pressure into a bed over a smaller surface area.

Back sleepers usually enjoy something that can help distribute their weight evenly over the surface of the bed. A medium feel often works for these folks as this will fill in the gap between their hips and shoulders without throwing off their alignment.

Stomach sleepers often drift towards a firmer bed. These types of mattresses keep their hips elevated and level with their shoulders. An overly soft bed could cause their hips to dip too low into the mattress.

Combination sleepers need a bed that targets all 3 sleeping positions, usually something with a medium feel and more responsiveness to help them move around.

Whatever position you sleep in, be sure you are getting something that caters to your body type so you can get the proper support your body needs.

Firmness Level

The firmness of your mattress is going to affect how you sleep. Something overly soft can leave you feeling stuck in bed, while something too firm can feel like concrete.

Beds are usually categorized as Soft, Medium, or Firm, with some variance in between. Certain brands may use different firmness titles, so reach out if you are unsure.

Couples Sharing Space

A King mattress could be great for couples wanting to sleep together but don’t want to fall asleep cuddling. This lets sleepers spread out while also giving more room for sexual activities.

If you have kids, a King mattress offers enough space for family cuddles in the morning.

Trial Period

Most companies offer some sort of trial period. Some brands even offer up to a full year. These trials allow shoppers to try these beds out in their homes within the allotted time and if they are not satisfied with their purchase they can either return their mattress or exchange it for a new model.

Warranty

Brands offer varying warranties, some even provide lifetime protection. Warranties typically cover manufacturing errors or abnormal wear and tear of a product. If damage occurs within the time of the warranty, the brand will usually ship their customers a new mattress.

Certifications

These are given by third parties that test beds for safe amounts of chemicals and heavy metals. Certifications are also given for brands that have gone above and beyond national safety requirements and strive to clean up their production with organic and all natural materials and manufacturing. These certifications can vary, so be on the lookout between brands.

Additional Features

Some brands will provide extra services and features. This could be anything from handles that make the bed easier to carry, all the way to White Glove Delivery, a service where your bed is installed for you. Some mattresses may be hypoallergenic, a smart bed, or have special features that help with edge support or cooling.

Frequently Asked Questions

Are there any cheap models?

King beds are typically more expensive, so a less expensive model could present huge savings. There are cheaper models out there, but be careful that you are not confusing “cheap” with “affordable.” So you can get the most out of your money, do your best to research by comparing brands and materials.

Check out our top budget options.

Are they worth the money?

Yes and no; some beds are going to be far more expensive than other brands that sell a similar or identical bed. Again, this is where it is important to compare brands to make sure you are getting a fair deal. There are plenty of good King sized mattresses out there that are worth the price tag.

Should I use a king topper?

If you are buying a new bed, you may as well buy it right the first time and get what you are looking for in a mattress and not spend additional money on a topper. If you currently have a King and think it needs just a slight adjustment, a topper could be a good way to get the feel you want.

I think we’re all nerds, but I’m probably the biggest nerd in the group. Put me nose deep in a spreadsheet and I'll start smiling.

I love to travel, hang out with positive people, and love cycling when I find the time!

My hope is that everyone who visits our site will walk away with a fresh perspective. I think too many people in society downplay the importance of sleep. In my opinion, it’s the difference between an average life and an amazing one.
