Buyer’s Guide Of King Size Bed In A Box

Now you know the best options for king size mattress in a box. But, do not make the buying decision without checking the following factors.

Construction: All the beds are manufactured using different materials. Some use regular foam while others are constructed with memory foam.

Some have gel beds for cooling purpose, and several mattresses have inner springs for the support, comfort and motion isolation.

Generally, we divide cushions into three different categories, memory foam, innerspring and hybrid, where the hybrid is a mixture of memory foam and steel coils. Then there is a fourth type of bed, where brands use their patent material to manufacture them.

As they are made of different materials, different mattresses accommodate different users. There is nothing called a perfect mattress. The same bed that feels soft to you may give another person a firm feel. It all depends on your personal preference, body weight, and size. So, choose a bed according to what you like and prefer.

Comfort level: Another area that needs your consideration is the firmness level of the mattress. Medium firmness suits most of the sleepers, and that is why we have tried to include most of the cushions that are medium firm. Still, check the firmness level of the mattress and make the decision based on whether you need a soft or firm bed.

Shipping and returns: That is a very straightforward thing to check. Most of the online companies ships the bed without shipping charges and also take it back within the trial period.

Still, you should check both the things – shipping charges and return costs. If you do not like the mattress within the trial period, whether you or the company will bear the return shipping charges.

Trial period: An average trial period in the mattress industry is 100 nights. Within the trial period, you can call the company to take the mattress back or give you a replacement if you are not satisfied with the comfort or material.

Few companies also offer a trial period of up to 365 days. Yes, you read it right, you can keep trying the mattress for a year and get a refund if you do not like it.

Warranty: Another major factor that you should check is the warranty on a bed. The average warranty that you may receive on any bed is ten years.

However, several companies provide a warranty period of up to 25 years or even a lifetime. The average life of a mattress is eight to ten years, but still, if you have extended coverage, it gives you the peace of mind that you can facilitate its repair whenever needed.

Bottom Line

You might feel odd buying a mattress through Amazon as you are not able to try it. However, think of a scenario where you visit a showroom filled with all the cushions in the market, but the salesman is pushing you to purchase a bed that will give “him” the highest commission. Think yourself that you will buy the bed based on what you see or what you listen.

We have given you the best king mattress in a box, and now it is your turn to make the decision. We hope that this buying guide will be useful and you will be able to buy the right king size mattress in a box.
