Marten: Hey guys, Marten here from Mattress Clarity.
If you're a larger person like me, you may have trouble finding a mattress to meet your
needs, but today I've got two mattresses made specifically with larger people in mind, the
Saatva HD and the Helix Nightfall.
I want to talk about the construction of these two mattresses, the similarities, the differences
and who should get one over the other.
Stick around.
[music]
Let's start off by talking about the similarities between the Saatva HD and the Helix Nightfall.
First off, they're both made specifically for larger people.
They're very supportive mattresses with some extra high density layers to support heavier
weights.
In addition, they're both hybrid mattresses so they have supportive coils underneath and
softer comfort layers on top.
Because of those coils, they're also both very breathable mattresses and overall, they're
both very durable mattresses.
Now let's talk about the differences between the Saatva HD and the Helix Nightfall.
First off, the Saatva HD is taller than Helix Nightfall.
The Helix Nightfall is going to be softer than the Saatva HD.
The Saatva HD was also a hybrid.
Has a little bit different feel than the Helix Nightfall.
It has more of a pillow tops.
The feel is a little bit different.
The Helix Nightfall is going to have less of a luxury design than the Saatva HD but
is more affordable than the Saatva HD.
Now I want to talk about the construction of these two mattresses.
If you want to see more information about the construction though, definitely check
out our individual reviews for both mattresses but starting with the covers and then working
our way down.
With the Saatva HD, you have an organic cotton cover topped with comfort foam.
With the Helix Nightfall, it is dual layer.
The top is very soft and stretchy.
The bottom is very breathable, helps with airflow.
With the Helix Nightfall, you can actually zip this cover off and put an ultra-cooling
cover on top to make it sleep a little bit cooler.
It terms of the comfort layer, on the Saatva HD, it first has a layer of a Talalay latex
foam so very durable.
It's also zoned to be more supportive under the heavier parts of your body.
Great for heavier people, ventilated for more airflow.
Beneath that you have some memory foam and some support foam as well.
Over on the Helix Nightfall, on top you have the Helix dynamic foam.
It is soft and also very responsive.
Below that, some high density memory foam and below that, a transition layer.
Moving down to the coils, with the Saatva HD, you have very supportive coils.
They're 12.5 gauge.
Very thick, very supportive.
In the center of the mattress, the center of the coils is actually zoned to be firmer.
Under your lumbar area you'll feel more support.
Moving over to the Helix Nightfall, the Helix Nightfall doesn't have that zoning but the
coils are still very, very supportive.
They're extra tall.
Very supportive for heavier weights.
Again, both these mattresses are made specifically with heavier people in mind.
Over here at the Saatva HD, very supportive coils.
Zoned there as well.
The Talalay latex layer is zoned for heavier weights so definitely made for heavier people.
Helix Nightfall, taller coils, extra transition layer to offer extra support for heavier people.
The feels are going to be a little bit different with both these mattresses.
With the Saatva HD here, it's going to have more of that pillow top feel.
The top is tough and quilted with a comfort foam.
The Helix Nightfall, you don't have that so more of a flat feel overall.
More of a bounce foam feel over coils.
In terms of breathability, both mattresses should be about equal so a lot of room for
airflow with the coils, some ventilated layers as well.
Finally, in terms of durability, I would probably give the advantage to the Saatva HD.
The Helix Nightfall is very durable as well but you have some more luxury materials in
the Saatva HD.
It should be a better long term investment.
Now let's talk about differences in firmness and feel.
In terms of firmness, I put the Saatva HD at an 8 out of 10 and the Helix Nightfall
at a 7 out of 10.
I will just note, I'm only 230 lbs.
If you're much larger than me, you might press further into these mattresses and feeling
to be firmer or software than I did.
In terms of feel, the Saatva HD has a pillow top feel on top.
Overall more of a hotel mattress feel.
Even though it's a hybrid and the Helix Nightfall is as well, the Helix Nightfall does feel
different.
The Helix Nightfall has more of a balanced foam feel on top and beneath that, the coils.
The comfort layer is not quite as thick as what you find on the Saatva HD so you definitely
feel the coils more on the Helix Nightfall.
Now I want to talk about how I feel in different sleeping positions on both mattresses starting
on the Saatva HD.
On my back I feel absolutely fantastic.
My hip sinks into the pillow top just the right amount.
Feel great lumbar support from the zoning there.
It's very, very nice for back sleeping.
Moving to my side, I'm feeling a little bit of pressure but decent press relief overall
specially on my shoulders and my hips.
On my stomach, great overall support.
My hips don't sink in whatsoever.
Just fantastic for stomach sleeping.
Moving to the Helix Nightfall on my back, also a very, very nice match.
My hips sink in the right amount.
Some nice lumbar support and some contouring form the top foam layers.
Moving to my side, feeling some more pressure on my shoulders and on my hips than I felt
over here on the Saatva HD.
I'm pressing pretty far into the mattress putting some pressure on my shoulders and
my hips.
Moving to my stomach, it's definitely supportive overall.
I'm not bowling at the hips whatsoever.
Also a nice match for stomach sleeping.
Here at Mattress Clarity, we like to mix some objective opinion with objective tests, and
one of those tests is the pressure map.
What we do is we lay the pressure map on top of the mattress.
I lie down on my back, side and stomach.
You'll see anywhere from blue for no pressure, all the way up to red for high pressure.
Pulling up both the side sleeping results for the Saatva HD and the Helix Nightfall,
you'll see over in the Saatva HD there's a little bit of red on my shoulder.
With the Helix Nightfall, you'll see some heavy red on my hips and some red on my shoulders.
That lets me know the pressure relief overall is better on the Saatva HD.
If you sleep with a partner, you want to think about two things.
It's motion transfer and edge support.
Motion transfer is if you're lying down on one side of the mattress and your partner
moves around on the other side, are you going to feel that movement or not?
Edge support is if you're sitting down near the edge of the mattress, if you're lying
down, are you going to feel secure or more like you're going to roll off the mattress?
In terms of motion transfer, I gave the advantage to the Saatva HD.
There's more bounce on the Nightfall over there so definitely doesn't have the best
motion transfer on top.
With the Saatva HD I saw less disturbance so a better fit for couples in that respect.
In terms of edge support, I would also give the advantage to Saatva HD.
A much more supportive mattress, a firmer foam and case around the edge so overall,
better edge support.
Now the moment you've all been waiting for.
Which one of mattresses should you get?
In terms of who should get the Saatva HD, first off, if you're a much heavier person
in the 300 to 500 lb weight range, I would definitely go with the Saatva HD.
Overall, it is more supportive than the Helix Nightfall.
Should be able to handle heavier weights.
Also, if you want something more luxury and durable, you should definitely check out Saatva
HD.
It has some high end components, definitely some high density components.
Overall it should be a longer lasting investment than the Helix Nightfall.
If you like more of a pillow top feel, more of that hotel mattress design, the Saatva
HD is definitely something you should check out.
Last but not the least, if you just want something firmer, the Saatva HD is firmer than the Helix
Nightfall.
If you want that extra support -- even if you're a larger person, you just want that
extra, extra support -- I would go with the Saatva HD.
In terms of who should get the Helix Nightfall, first off, if you want something more affordable,
the Helix Nightfall is definitely the clear choice.
Right now it's much more affordable than the Saatva HD so if you want to save some money
up front, go with the Helix Nightfall.
Off of that, if you're a larger person but you're below 300 lbs, the Helix Nightfall
should give you all the comfort and support you need and again, you can save some money.
If you want more of a bouncy responsive feel without the pillow top, the Helix Nightfall
is definitely the better choice.
Without the pillow top, it has more of this balanced foam feel on top with coils beneath
that.
If you like that feel overall, check out the Helix Nightfall.
Last but not the least, if you want something a bit softer, go with the Helix Nightfall.
It's definitely softer than the Saatva HD so if you want some more give on top of your
mattress, the Helix Nightfall should definitely work for you.
In the end, it shouldn't be too difficult to choose between the Saatva HD and the Helix
Nightfall.
The Saatva HD is better for people between 300 and 500 lbs and those that are looking
for something more luxury and more durable.
The Helix Nightfall on the other hand is better for people under 300 lbs and those who are
looking for something more affordable.
That's about it.
