Top 5 Best King Size Mattresses
LINENSPA 6 Inch Innerspring Mattress – King
Innerspring? Really? Yes, we’re starting this top list with the traditional innerspring mattress.
For a fact, innerspring mattresses are durable. Their costs are also much more affordable even for this huge King bed.
Nowadays, makers have improved the construction much better. At the base of the bed, you’ll find heavy-gauged metal coils that provide exceptional support for your back and overall body.
On top of that is a felt liner. Then, at the very top, you get your own foam layer for added cushioning. It’s overall very comfortable to sleep on.
The fire-resistant barrier inside the bed can protect you and your loved ones in unexpected situations because it’s made according to the safety standards.
The mattress is 6 inches high. We’d say that it would fit better for people of average size (130 – 230 lbs). Despite that, the mattress does hold up pretty well.
On the firmness scale, we’d rate this one somewhere in between the medium firm to firm marks. Still, it’s comfortable to lay your back on the bed.
This is a great mattress for two people or a parent and a kid. Using a box spring underneath it is not required but you can. The bed itself with the innerspring base is strong enough to stand on its own.
As mentioned, this is a quite firm bed. Some folks, however, don’t like this at all.
Medium to firm beds can be helpful if you’re struggling with back pain. By not sinking too much into the bed, your spine will be aligned to its natural curvature.
By understanding that, we think you’d be able to make the best decision for your needs. This is a highly recommended choice if you’re on a budget and need a good quality King mattress. Have a go at it for yourself!
- Strong innerspring base
- Soft & comfy cover
- Comfortable to sleep on
- Holds up well
- Fire-resistant barrier
- Too firm for some
Ashley Furniture Signature Design – 12 Inch Chime Express Memory Foam Mattress
Memory foam is the love of many bedrooms from households to luxurious hotels. This King mattress won’t disappoint your high hopes!
The one important thing to note when you’re buying a memory foam mattress is its CertiPUR-US certification.
With this certification, the mattress you’re getting has been fully verified for being free of harmful chemicals like mercury, formaldehyde, or phthalates.
You can check the companies that have this certification here: https://certipur.us/list-of-participating-companies/#directory
Luckily, Ashley is one that has been fully certified. In fact, this is a brand that many families love and trust.
You’ll absolutely love this 12-inch all-foam mattress. It fits well with any bed frames from box spring to an adjustable base. You can even put it on the floor if you like because it’s very high.
Two people can sleep on the bed nicely without anyone disturbing the other. Also, you two won’t overheat. The foam allows air to travel in and out regularly throughout the night to ensure a comfortable sleep temperature.
At the base of the bed, you’ll a thick 8-inch foam that helps support your spinal alignment and your neck. Stacked on top of that are memory foam and transition foam layers. The stretch knit cover helps wrap it all together.
All of these materials are incredibly supportive and hypoallergenic. If you have a sensitive nose, you can rest surely on this bed without worrying about those harmful allergens.
That said, some folks still find sleeping on the bed a bit warm. To solve this issue, you can get yourself a cooling mattress topper or a bed sheet with a high thread count. It’s super easy!
You need to wait about 24 hours for the bed to become fully inflated when taken out of the box. Usually, it’s much quicker than that.
We find it surprising that some sleepers think this bed is too hard. Again, we can’t speak for everybody because it’s their personal taste. It’s worth mentioning so that you know.
Overall, this is an awesome bed at a reasonable price that you won’t regret buying. Don’t miss out!
- All-foam mattress
- Great support for the back & neck
- Super comfortable
- Certified materials
- A lot of space
- Good support for back pain
- Sleeps quite warm
LUCID 10 Inch Gel Memory Foam Mattress – Medium Feel
So far, you’ve seen a memory foam and an innerspring mattress. Now, let’s meet this awesome gel memory foam mattress!
Besides the affordable price, what we love about it is the firmness. The Lucid mattress is about medium on the firmness scale, which is music to the ears of people who are suffering from back pain. It will feel just right.
Like we said earlier if you don’t like the warm feeling you get when sleeping on memory foam, you can get a cooling mattress topper. But guess what? You don’t have to now.
On the technical side, they infused cooling gel right into the bed. Together with the foam, this gel helps absorbs your heat and dissipate it more evenly throughout the bed’s surface.
Thanks to that, you get cool, comfy sleep that leaves you feeling refreshed and energized the next morning. Isn’t that what everyone wants? We bet!
The Tencel blend fabric cover also makes it soft and comfortable when resting on the mattress. We find the bed has great support when you’re sleeping or sitting on it.
Even after years of usage, it won’t leave any visible body indentation on its surface. You can watch TV in bed, eat in bed, or do whatever you want because it holds up well.
But we do need to point out some conflicting opinions about the firmness. For some, this is too hard. For others, they find themselves sink too much into the bed.
We’d say that for average-sized sleepers, you won’t sink in too much and still feel that plush foam. For heavy sleepers, you may sink in the bed a bit more. But we find that the firmness is not an issue for a 280-pound sleeper.
Overall, this bed delivers. Have a look into it and see if it fits your bedroom and needs!
- Cooling effect
- Strong support
- Certified materials
- Holds up well
- Firmness not suitable for some sleepers
SoundAsleep Dream Series Air Mattress - King Size
Hours of researching coupled with personal experience have told us that air mattresses one of the most durable and best pain-relieving mattresses there are.
Many people are turning to this option due to its competitively low prices and incredible quality in one package. Also, the mattress makes it so much easier when you’re moving.
If that sounds like something you’d want to try once in your lifestyle, this King size air mattress won’t disappoint.
We love that EZ built-in pump. Just one click and your bed is ready to inflate or deflate. The Sure-Grip bottom keeps the bed nicely in its place, so you won’t be disturbed during your sleep.
The #1 concern people have when buying air mattresses is that they may go burst like a bubble.
But you can rest assured. Thanks to the tough PVC material that’s puncture-proof, no sharp objects can damage your bed that easily—even your cut cats or dogs who get naughty sometimes.
Diving deeper into the construction, you’ll find strong air coils inside the bed. This is their very own Comfort Coil Technology that’s intended to give you sound sleep like on a cloud.
The carrying bag is handy when you’re out camping or having a picnic. The only thing we didn’t really like was the sound of the motor when running.
It’s very loud! But the good thing is you only have to stand it for 4 minutes or so. At the meantime, you can go grab a cup of coffee and when you’re back, there’s your bed waiting for you to enjoy.
All in all, we give this air mattress a 10/10. It works well for what it’s intended to do. We have sweet dreams on it and so will you. Have a look now!
- Super durable
- Amazing back support
- Feels like sleeping on a cloud
- Easy to inflate
- Easy to carry around
- Loud motor noise when inflating
Tuft & Needle King Mattress, Bed in a Box, T&N Adaptive Foam
Finally, we’ve come to the end of our list! What we have here for you is foam but not just like any type of foam you’ve seen before. What is it then?
Well, this is Tuft & Needle’s special Adaptive Foam. What this thing can do for you is to help your back relieve much more pressure and give you the optimal sleep temperature.
That’s why we recommend this product to heavy people. One customer around 280 lbs had a surgery a while ago and was looking for a bed to support his back.
He found that this mattress helped him drift off almost immediately and gave him much more energy and less pain when he woke up. It can work wonders for you and your partners as well if you’re struggling with backaches.
You can get a box spring underneath the bed, but it’s not completely necessary. This mattress also fits perfectly on many types of bed frames. If you have a platform bed at home, you can put it on as well.
The mattress also gives you an incredible sleep temperature. It’s not too hot and not too cold either. Thanks to the motion-isolating property, you can toss and turn how many times you like and still not disturb your partner.
Upon arrival, the package you get is a big white box with the company’s name T&N on the outside. We think one tiny little thing they could do to improve is putting two wheels on the box.
Believe it or not, this is something that has been done by some other bed makers. Because their product here is targeted at heavy people who may have back pain, who’s going to drag such a heavy box into the house or upstairs?
Oh my god, no way! Believe us, it’s quite a pain having to do all this unboxing and putting the mattress on the bed frame. Two wheels can make life much easier!
But, other than that, there’s nothing much to complain about such a great product from a great company. We highly recommend getting this one for your bedroom!
- Unique Adaptive Foam
- Sleeps comfortably
- Not too hot, not too cool
- Excellent back support
- High durability
- Body contouring
- Packaging could be improved
