Highlights
- medium firmness, can accommodate a wide range of sleepers;
- strong edges for more sleeping space;
- temperature-neutral design, suited for hot sleepers;
- individually wrapped coils for targeted support;
- quilted foam cover for extra plushness.
The Dreamcloud opens my selection of the best King size mattresses. This hybrid bed features an optimal level of firmness for almost any sleeper — medium. Along with that, the mattress has incredible edge support, so if you love snoozing closer to the side, this should be a perfect pick for you.
So, the edge support is ensured by a layer of individually wrapped coils, which also serves as the core supportive layer. Pocketed coils offer targeted contouring and remain sturdy and uniform no matter which sleeping position you choose.
If you’re concerned that a mattress will feel firm due to coils, don’t be. It’s actually pretty cushioning thanks to a pillow-top and two layers of soft, cradling foam underneath. These layers gently balance the rigidity of coils and offer you a soft hug and pressure relief.
Also, the hybrid construction means better airflow. The Dreamcloud sleeps cool, even though you may sink deeper into its comfort layers. The coil block promotes proper air circulation between the layers, allowing your body heat to dissipate during the night.
I really enjoyed sleeping on this mattress. It’s pretty cradling in all positions and offers you a uniform sleeping surface with strong edges.
Recommended for:
- Couples. The Dreamcloud has good edge support, which is essential if you share a bed with someone. Also, foam layers above the coils mask motion, so the mattress won’t transfer sharp movements from one side of the bed to the other.
- Large sleepers. The sturdy coil base distributes your body weight evenly across the mattress surface and helps maintain the natural curve of your lumbar region.
- Hot sleepers. The coil block promotes good air circulation and helps withdraw your body heat, so you’ll sleep cooler.
Cons:
- might not be firm enough for stomach sleepers or heavier users;
- very heavy and hard to move.

Benefits of Having a King-Sized Mattress
Now, let’s outline how a good King-sized mattress can change your sleeping routine so that you make sure you’ve picked the right size:
- More space. Obviously, you’ll have more personal space on a King mattress. This will help you get cozier and find a comfortable position to drift off more easily. Along with that, if you allow your pets to sleep on the bed — or, if you occasionally co-sleep with your kid — a few extra inches of space will also be beneficial.
- Better support. The bigger area of a King-sized mattress allows for more even weight distribution. For example, if your partner is a large sleeper, you won’t feel how deep he dives into the mattress layers and your sleep will be uninterrupted.
- Lower motion transfer. Due to the larger area, King mattresses also muffle sharp movements more efficiently than Queen ones. This might be an advantage for restless sleepers and their partners.
- Healthier sleep. Overall, by having more room to move and get comfy, you can easily improve your sleep quality and even alleviate your sleep disturbances (assuming they were caused by a lack of space).
Aside from all of that, it would be unfair not to mention how luxurious a King mattress looks in a master bedroom. If you choose a high-profile bed and properly decorate it, you can easily turn your bedroom into the royal chambers.
F.A.Q.
How to get a King-size mattress upstairs?
Most mattresses are shipped vacuum-sealed in a box, so you just need to carry it upstairs and unbox it right in your bedroom. If your King mattress is delivered in its full size, you should measure the passages and staircases to make sure it will fit through.
How much does a King mattress weigh?
Depending on the materials used, a King bed may weigh from 100 to 180 pounds. But the thinner it is, the less it will weigh.
How to dispose of your old King-size mattress?
Many mattress companies offer free mattress removal when you purchase a new bed from them. You can also donate it to your local charity or contact a recycling facility in your area.
Conclusion
King mattresses are popular for a reason. They give you more space to stretch, which is especially important if you share a bed with someone who sleeps in a starfish position. I’ve collected five models that can please even the pickiest sleepers. They have excellent value for money and can offer you great support and serve for years to come.
My personal favorite is the Dreamcloud, and there are many reasons for that.
First of all, this mattress offers almost universal comfort thanks to its balanced medium feel. It has strong edges and can effectively support both you and your partner, helping you maintain proper spinal alignment during the night. Plus, it doesn’t sleep hot, which is always a huge bonus!
But don’t forget to measure your room before purchasing your new King-size mattress, to make sure it will fit well. And always double-check the warranty to protect your investment. After all, it’s supposed to serve you long.
So, why are you considering getting a King-sized bed? Does any model of those above seem suitable for you? You’re welcome to share in the comments below!
