Best twin mattress under $100 in 2023

Finding the best twin mattress under $100 is no easy task, but we're here to help you do just that. Mattress prices have been sneaking up of late, which means that you'll generally pay more for one of the best mattresses now than you would have done a year ago, and it also means that it's a lot harder to find a good twin mattress that'll cost you less than $100.

It's not impossible, though. There are plenty of sub-$100 twins about but many of those look suspiciously cheap to us; the sort you'd maybe put on a guest bed if you rarely have guests and don't much care how well they sleep, and definitely not the kind you'd want to put on a kids' bed. There are a few gems available for under $100, although to find some of them at that price you'll need to get them when they're included in the mattress sales.

You're not going to get the best quality or top features in these beds, but they're all quite comfortable and supportive for the price, and there's an option whether you're after memory foam, hybrid, innerspring or simply the best mattress for college students. If you need more choice and don't mind upping your budget a bit, see our guide to the best cheap mattresses. But for now, let’s take a look at the best twin mattresses under $100.

The best twin mattress under $100 in 2023 – as chosen by experts

Best hybrid

Finding the best twin mattress under $100 is becoming harder than ever, which means that if that $100 is your hard ceiling you're likely going to have to watch out for deals. Linenspa's 8-inch hybrid has an MSRP of $129.99, which is definitely a good price, but you can find it reduced on Amazon right now for $99.99.

That's an excellent price for a hybrid innerspring mattress that'd be best suited to a kid or teenager's bedroom. This one has a medium-firm feel, with a top layer of contouring and pressure relieving memory foam bringing the comfort, while a layer of steel springs underneath gives the mattress additional bounce and durability.

Thanks to the layer of springs that provide cooling airflow, this mattress isn't one that's likely to get too hot in the night, and as well as a twin bed it'd be a good fit on a bunk bed, day bed or in an RV. There's a 10-year warranty if you buy direct from Linenspa (which means paying the MSRP); buy from Amazon at the lower price and you can return it within 100 days free, or pay extra for up to 10 years' protection.

This mattress is a popular choice on Amazon with 71% 5-star reviews praising its value, comfort and support. Less favorable reviews find it too firm and question its longevity and edge support, as well as mentioning the off-gassing smell after unboxing; it's worth pointing out that Linenspa recommends letting the foam in this mattress expand for at least 24 hours before using it.

Best memory foam

We're quite keen on the Zinus Green Tea Memory Foam mattress as a cheap yet comfortable bed, and while you can't get that in a twin size for under $100, there's another Zinus option that's worth looking at. The Zinus 6 Inch Ultima Memory Foam Mattress has an MSRP of $125 but it's currently discounted on Amazon to a very reasonable $87.50.

Obviously for that money you're not going to get a whole lot of mattress; at six inches deep it's not going to be particularly comfortable for adults, but it'll be a good fit for a kid's bed. Like the Zinus Green Tea it features a top layer of green tea-infused memory foam, enhanced with charcoal to keep things fresh; underneath that is a layer of comfort foam that molds to your body shape to relieve pressure on joints, and the mattress is finished off with a thick layer of based foam for stability.

Beyond the breathable knitted cover there's not much going on to keep things cool with this mattress, so we wouldn't recommend it to anyone who sleeps hot. Be aware, too, that Zinus says this bed-in-a-box takes around 72 hours to expand to full size. Reviews for this mattress are generally favorable, with plus points being its comfort, pressure relief and of course its price; that said, less enthusiastic reviews point to the time it takes to decompress and its tendency to get hot, as well as lackluster customer service from Zinus.

Best innerspring

This highly rated innerspring mattress comes with plenty of coziness for your money. The design features independently pocketed 15-gauge coils, as well as quality foam and polyester between the cover and spring layer for optimal comfort. The foam is 100% GreenFoam Certified.

Like others in our list, this best twin mattress under $100 comes shipped in a box for your convenience. With 2 inches of plush foam, the firm-feel bed offers a plush ultra-soft surface, making it ideal for back sleepers who want support as well as a bit of extra coziness. At $81.99, the price cannot be beaten, and right now, Amazon is offering a further discount and you can get the Home Life Comfort Sleep 6-Inch mattress for $63.09. Bear in mind you will have to pay shipping on this one, so that could take the price nearer to $100.

There are plenty of happy customers for the HomeLife Comfort Sleep 6-Inch mattress and there are more than 2,225 reviews, and nearly 60% 5-star ratings. Positive comments mention great value, plenty of comfort and swift shipping, while some less positive comments mention cheaper build-quality including squeaky springs.

Best for kids

The Minnesund’s shallow height and narrow width makes this a perfect match for an IKEA daybed or children’s extendable bed. It's an all-foam mattress so it delivers plenty of support and comfort, as well as resilience, but its thinness means it's not really suitable for anyone other than children.

It has a removable cover and can be washed by machine, making it a perfect option for young families or households with pets. It is conveniently delivered in a roll, which is easy to unpackage, and it also comes with a 10-year limited warranty. Other features include a  child-safe zipper and foam that is more renewable and recycled.

This best twin mattress by IKEA has around 170 reviews on the brand’s website. It scores highly when it comes to value for money, and the feedback mentions it is one of the best mattresses on the  market in its category and that it works well as a firm floor-sleeping mattress with added cushioning for joints. More negative reviews were disappointed by the thinness of the mattress, finding it too firm and shallow for their needs.

How to choose the best twin mattress under $100

For under $100 it will be tricky to find the best materials and build-quality in a twin bed, however you will still find plenty of options available that will be perfectly good enough for your needs.

If you’re looking for a spare mattress for occasional use on a guest bed or if you need a smaller bed that will soon be outgrown by a child or a teenager, then a cheaper mattress is the ideal solution.

Look for all the same things you would expect in a more expensive mattress, such as firmness, cooling qualities such as breathable cotton covers, or extra layers of comfort if you’re after added pressure relief.

If you’re ordering online, you will still find plenty of options that deliver for free and offer a decent warranty. However, you might not get the perks of more expensive mattresses such as a 100-night trial or free returns.

Should I buy a twin mattress for under $100?

Buying a twin mattress for under $100 is a good option if you are on a budget or need an extra mattress for your home for occasional use. However, it’s worth pointing out that a mattress at this price might not come with the same build quality as a more recognized brand, but you should still find enough comfort for your needs.

While a very cheap mattress is rarely discounted further, if you did want to spend a little more on a better-quality mattress, then many of the top brands have frequent sales including on their twin sizes.

However, bear in mind that while you are unlikely to find an option for under $100 with a top brand, you will get a mattress that will last you longer, offering better value for money in the long run.
