The advantages of a memory foam mattress are numerous. First of all, such a mattress gets into the same shape as your body and aligns with your spine, which increases your comfort and ultimately relieves back pain. Secondly, if somebody else is sleeping with you in the bed, you will not feel his/her movements. The space that is left between you and that other person will not change its shape, no matter how much you toss and turn.

But, keep in mind that if you purchase a memory foam mattress, you must follow these rules:

  • Once in half a year turn it over to avoid deformation
  • Place the mattress on a completely flat base
  • Do not clean it in high temperatures
  • Do not keep it bent or rolled for a long time

If you stick to those simple rules, I guarantee you that this mattress will help you to be more comfortable in your sleep, improve the health of your spine, and neck, and you will wake up pain-free every morning. Also, if you purchase this king size mattress, it will be shipped right to your door in a small box, so it will be very easy to set it up.

Popular Mattress Buying FAQs

If after reading the buyer’s guide, you still have questions left about picking and buying the best mattress, check out this section. For your convenience, I gave answers to the most frequent and popular questions about purchasing a mattress. Read on to find out how big a king and California king mattress is, their weight, and the ideal box spring size for such a mattress.

In different countries, there are different bed sizes. In the US, the king-size bed is 76′′ x 80′′. It means that the mattress is 76 inches wide and 80 inches long. It is the best size for a couple. There would be even enough space to sleep comfortably with pets or children. However, this is not the biggest mattress size.

Californian king mattress size is almost the same as the normal king size mattress but has a slight difference. If you see that a mattress is California king, this means that it is slightly longer than an ordinary product of this type, and a bit narrower. So, the actual size of such an item is 72′′ x 84′′.

The weight of a king-size mattress depends greatly on the manufacturer. But, usually, the weight is around 130-180 pounds. Also, the weight depends on the material out of which the item was made, the density, layers, and many other factors that were implied during the manufacturing process. A good thing is that now the manufacturers deliver almost any mattress in a small box. This makes it much easier to unpack it and place it on your bed.

The box spring should be of the same size that the mattress is. So, if your mattress is a king-size, it means that the box spring dimensions should be the same as the king size mattress dimensions. The size is as follows, king size – 76′′ x 80′′, california king – 72′′ x 84′′.

Choose the Ideal Mattress for a Good Night Sleep

As you see, there are a lot of choices that you have when it comes to purchasing a new mattress. And there is a lot to take into account and to consider before making that choice. Before buying one, I advise you to make a checklist and decide on what kind of mattress you are looking for. Think about your preferred density, how many layers you want it to have, decide on your budget, and think about the size, as some king size mattresses tend to be shorter than you imagine. In such a case it is best to get a california king size mattress.

The best way to improve your sleep cycle and become a healthier and well-rested person is to get comfortable and suitable, especially for your mattress. You’ll be amazed at how quickly you feel the changes. There is no one mattress that suits everyone. One person may be completely satisfied with a hybrid mattress, but the other person may prefer only a memory foam one. But this doesn’t mean that the hybrid mattress is in any way better or worse than the other one. This simply means that some people feel more comfortable sleeping on a mattress that doesn’t have inner springs.

But, still, there are a couple of products that almost every person would enjoy. One of such mattresses is the Linenspa hybrid mattress. It is a perfect combination of price, quality, and functionality. It doesn’t matter whether you are a college student, or a retiree, you will be satisfied with this product.

I hope I was helpful, and you are ready to make this important choice. Can you recommend some other good mattresses to include on this list? Share your thoughts and experiences in the comments section below.
