What experts liked

With three layers of foam, the Amazonbasics 8-Inch Memory Foam Mattress is one of the softest mattresses available right now.
- Sleep Rex
As a light sleeper, I also appreciated how this mattress performs with motion transference.
- Business Insider
Ideal for people who prefer close-conforming mattresses.
- Sleep Foundation
Better temperature neutrality than most all-foam alternatives.
- Tuck
The mattress provides an adequate amount of support under your lower back and trunk.
- Slumber Yard
This mattress could be excellent for lighter individuals and children as they’re not likely to sink all the way to the base of the bed.
- Sleepopolis
The layer of aerated foam and the wavy surface to the support core add breathability and improved temperature regulation.
- Sleep Help Institute
The plush top foam layer should provide pressure relief that eases pushback, especially in the shoulders and hips when the shopper is lying on their side.
- Sleep Advisor
AmazonBasics Memory Foam Mattress incorporates three strategically placed layers to offer premium comfort, contoured support, and maximum stability–thanks to a dense foam core.
- Sleep Health

What experts didn't like

No handles to help when moving it.
- Sleep Rex
There was some odor from the off gassing, and while unpleasant at first, the smell dissipated within 48 hours and hasn't lingered since.
- Business Insider
As an all-foam mattress, the AmazonBasics mattress is liable to trap some heat.
- Sleep Foundation
Questionable edge support.
- Tuck
Given the simple, all-foam construction of the mattress, we just don’t think it’s the best option out there for folks who weigh more than 250 lb.
- Slumber Yard
If you’re sharing the bed with a partner, its lack of edge support could also be a woe to consider.
- Sleepopolis
The off-gassing smell may seem to linger longer than 72 hours for those sensitive to smell.
- Sleep Help Institute
The simpler construction of this item may not allow for enough stability when used by a shopper over 250 pounds.

An Overview On King Memory Foam Mattresses

If your old king mattress is no longer comfortable, giving you backaches, making you sweat and not letting you have a restful sleep any longer, it’s time to invest in a new one. Memory foam is a leading option in mattress choices because of the immense comfort it brings. Did you know that this material was actually made for NASA? The viscoelastic qualities of the memory foam made it perfect for helping pilots and astronauts stay safe in crashes.

There are a few different types of memory foam mattresses available, and each provides different benefits to its users. Traditional memory foam is a good choice for warm sleepers. It’s able to absorb heat, so it keeps you feeling cool all night. Plus, the type of support it provides helps to decrease stress on your joints.

Open-cell memory form is another option. If you don’t like the feeling of sinking into a mattress, then you’re in luck. This one doesn’t make you feel like you’re falling into quicksand. Plus, it also has strong heat regulation qualities so that it can help you have a restful sleep without feeling hot and sweaty all night. Gel memory foam is perfect for very hot sleepers. It works like a gel ice pack, with the gel fully infused into the mattress to help keep the body cool.

Regardless of what kind of king memory foam mattress you choose, you’ll have a good night’s sleep. Most memory foam mattresses are made with several different layers of materials. They work together to provide the right kind of support, comfort and cooling features you need. The top layer of memory foam contours to your body but it doesn’t provide the feeling of sinking in. This helps to reduce pressure on your joints and lets your body fully relax.

The King Memory Foam Mattress Buying Guide

  • An element you should keep in mind when looking for a new king memory foam mattress is what style of sleeper you are. Memory foam is ideal for back sleepers and side sleepers because it conforms to your body to take pressure off your spine and joints. If you’re a stomach sleeper, however, memory foam may not be the best choice. Some stomach sleepers find that the memory foam makes them feel like their face is surrounded by the mattress.
  • Consider what type of memory foam you want for your king mattress. All of them provide comfort and support, but gel memory foam is excellent if you find yourself sweaty at night. If you sleep very warm, then the best kind of mattress is a gel memory foam. It’s specifically designed to help keep the body cool all night, and will help regulate the temperature so you have a restful sleep.
  • Take a look at the mattress firmness. For memory foam, you’ll want to pay attention to the indentation load deflection or IDL. The higher the number is for IDL, the firmer the mattress will be. When shopping online, you can’t get a feel for the mattress in person, which is where IDL can come in handy. An IDL of around 12 is a very soft and cushy mattress, whereas an IDL of 50 is a firm and supportive mattress.
  • If you want a durable king memory foam mattress that lasts for a number of years, then pay attention to the memory foam density. Ideally, the memory foam mattress should have a 5-pound per square foot density for a high-quality product. Anything under 3.5 pounds per square foot will not last very long.
