Stand Out Features

  • Easy Shipping: All Zinus mattresses have this feature, but it’s one of the reasons this company stands out. Their mattresses are all compressed and rolled in an easy-to-handle box so delivery day is much less of a hassle.
  • Affordable: You may not even need to reach into your savings for this mattress. The price of the Zinus 5 Inch Biofusion Mattress is very affordable making it easier for those on a budget to try their hand at a comfy night’s sleep.
  • 10-Year Warranty: Even with its low price tag, it’s always nice to know that the company has your back should anything go awry. With the Zinus 5-inch Biofusion Mattress, you’ll have a long 10-year ‘worry-free’ limited warranty so you can literally rest easier.

The Positives


Quite a few users of the Zinus 5-Inch Memory Foam Biofusion Mattress have noted how comfortable it is. It is on the softer side but still firm, and that seemed to be the best combination for a lot of users.

A number of testers have also noted that the mattress offers a good night’s sleep and even pressure relief (mostly when brand new; we’ll get to that in a minute.).

The memory foam conforms to your back and the rest of your body to give you a comfortable and supportive rest.


Zinus knows investing in a good night’s sleep shouldn’t be taken lightly, so this mattress comes with a 10-year limited warranty.

This means, if anything should happen to your mattress due to a defect in the materials or because the manufacturer did something wrong, you get a refund or can exchange your mattress for a new one.

While this is a great feature, it can also give you peace of mind when purchasing. If it doesn’t work out because of a problem with the mattress itself, you aren’t going to lose money.

Keeps Firmness

The mattress is also rated shockingly high (for a five-inch mattress) for keeping its firmness. This may be thanks to its general softness, but it’s enough for many users to rate it highly.

Any back-pain issues could possibly be helped with this Zinus mattress since the foam conforms to your body, but it may be due mostly to the high-density foam base layer as well.


One positive that stands out is the price. It’s priced below $200. It’s uncommon to pay just a couple hundred dollars for a brand new, comfortable mattress. That is an insanely good deal!

Most mattresses start around the $300 range (for smaller sizes) and go up from there; the fact that this bed seems to have some happy users and a low price is outstanding.

Whether you buy this mattress and find that it works for you or not, you will not be losing much money in the process.

This also makes this mattress a suitable option for a guest bedroom, dorm, or even a cottage. You won’t have to skimp on a proper night’s sleep because of your budget.


The uses for this 5-Inch Memory Foam Biofusion Mattress are almost endless.

Sure, you can put it on a box spring on a normal bed frame, but it is also great for daybeds, bunks beds, trundle beds, and may even work on certain futons.

The five inches makes it great for kid beds too, or really any place where you need a mattress that can’t be too tall.

Even fit in a camper if you have one that’s big enough!

Helps Block Odors

Because every mattress made by Zinus includes green tea extract in it, the mattress stays fresh and almost odorless. Active charcoal is also added to the mattress to absorb any moisture that gets on the mattress.

The green tea extract is normally used as an antiseptic and an antimicrobial agent on the skin and in different products, so you can imagine how it will keep germs away from your mattress as well.

The bed also includes Bio Foam (i.e. Biofusion) which replaces some (about 12%) of the petroleum that is normally put in mattresses with plant oil. This also helps keep the mattress fresh. (Never a bad thing!)

Quality Materials 

Not only is the Zinus 5-inch Biofusion mattress made with those helpful materials above, it’s also built with high-quality foam as well.

The mattress is CertiPUR-US certified, meaning it has undergone a number of rigorous tests to ensure the mattress isn’t only durable, but safe.

The test also ensures that mattresses aren’t made with any damaging materials like mercury, lead, or heavy metals and that it is free from harmful ozone depletors amongst other safety checks.

Just because this mattress is affordable, doesn’t mean it skimps on quality or manufacturing. So you can rest assured knowing your mattress is safe for you and your loved ones.

The Negatives


While this mattress may be enough support for a kid, five inches of memory foam isn’t going to cut it for most adults. We’re just too heavy, and you’ll likely feel the box spring through it.

Maybe that is why the price is on the lower side as well; because it’s for smaller, kid-size beds rather than for an adult who really needs the support.

One user even stated that if they put two of the mattresses on top of each other, then they would have enough support. Though for the price, you very well could!

Not Durable

The durability of the mattress was also an issue for users. The foam is just not heavy-duty enough to hold a lot of weight (the site does not say any weight limit for the mattress).

One user stated that if an adult was using it infrequently (as a guest bed, maybe) or if it was a child’s mattress, only then would it be a reasonable buy.

Other users stated that the mattress provided great pressure relief and support, but only when the mattress was new. After a couple of months, that wasn’t the case anymore.

If you’re larger, taller, or heavier, this may not be the mattress for you for the long run.

While the Zinus 5-Inch Memory Foam Biofusion Mattress has a lot of preventative measures against smells, it does have an odor when you first receive it.

This will probably last up to 48-72 hours. That might mean you put it in another room until it’s done airing out, or it might mean sleeping somewhere else for a couple days.

If you are sensitive to smell in any way, it may be wise to shop elsewhere.

That being said, most brand new beds do come with some sort of chemical smell, especially memory foam mattresses and those that are packed compactly for shipping.

Iffy Customer Service

The customer service of Zinus has also been an issue for some users.

A few people couldn’t get any response from customer service, while others didn’t get their problem solved even when they did reach someone.

They do have a website and a contact form to get in touch with them if you need to, but according to a good number of reviews, it was more of a hassle than a service.

Overall Verdict

After reviewing the positives and the negatives, we would recommend the Zinus 5-inch Memory Foam Biofusion Mattress – for specific people.

If you want to get it for a kid’s bed, knock yourself out. But for a heavier adult, there is not enough support and it’s not durable enough to make it worth it.

If you have the budget, it’s better to save up for a more expensive mattress that is comfortable and helps you get a good night’s sleep, than to try out one like this and be disappointed.

Though if you’re looking for a quick fix, are on a budget, or are looking for a guest bed, this may be an option for you.
