Both are tall coil beds, and Sleep Foundation named the Helix Midnight Luxe its best mattress overall for 2026. The main practical differences are price, how many feels you can pick from, and what a return costs early on.
Pick the Saatva Classic if you want three feels, a crew to set it up, or a Split King in one order. A Queen is $1,904 on sale, and a return costs $99 any night of the year.
Pick the Helix Midnight Luxe if you want the lower price ($1,874 for a Queen), a free return after 30 nights, or you're a side sleeper. Sleep Foundation scored it 9.5 to 10 there in every weight group. You'll unbox a 115 lb bed yourself unless you pay Helix's setup fee.
No lifting. A crew sets it up in your room and takes the old bed, free.
Three feels, two heights. Plush Soft, Luxury Firm or Firm, at 11.5 or 14.5 in.
Easier to move on. NapLab scored it 9.9 out of 10 for response time against Helix's 8.4.
Where the Helix Midnight Luxe wins
Lower price. $30 less for a Queen on sale, and cheaper at every other size.
Sleep Foundation's top pick. Named best mattress overall for 2026, with 9.5 to 10 for side sleepers.
Less motion. NapLab scored it 9.7 out of 10 for motion transfer against Saatva's 7.4.
Side by side
How do the key facts compare?
Every value comes from each brand's own pages, checked Sep 27, 2026. The biggest gaps are price, how many feels you can pick, and what a return costs before night 30.

What will each bed cost, including setup and a return?

Firmness
Feels checked on each brand's site · Sep 27, 2026
What firmness options can you choose?
Why this matters to you: Brands name their feels their own way, so one brand's Medium can be another's Luxury Firm. Sleep Foundation rates the feels it has reviewed on one 10-point scale.
The firmness choices for the beds compared here, on Sleep Foundation's 10-point firmness scale, where 1 is softest and 10 is firmest. Feel names are each brand's own; the note below flags any that differ or weren't rated. We don't test beds ourselves.
Sleep Foundation's firmness ratings. Saatva review updated Oct 14, 2025; Helix Midnight Luxe review updated April 3, 2026.
The Helix's one feel lands at 6, level with the Saatva's Luxury Firm. Only the Saatva lets you go softer or firmer.
Who fits
Which feel did Sleep Foundation score highest for your sleep position and weight?
Why this matters to you: Sleep Foundation scores each feel separately for lighter, average and heavier sleepers in each position, so a feel that suits one sleeper can score lower for another. These are one outlet's scores, not a promise of how a bed will feel to you.
Saatva sells three feels; Helix sells the Midnight Luxe in one. Below is the feel of each bed that Sleep Foundation's testers scored highest for each sleep position and body weight, out of 10. We don't test beds ourselves.

Tester results
What do review sites say about feel, cooling, partner movement and edge support?
Why this matters to you: Review sites score the same bed differently. Each uses its own scale and tests, so we show every score as it was published and never add them up into one winner.
We don't test mattresses. These are three outlets' published scores, each on its own scale, never averaged. The higher score in each pair is marked; a tie is not. Sleep Foundation reviews the whole Helix Luxe line at once, so it gives no separate overall or category score for the Midnight Luxe.
Scores as each outlet publishes them: Sleep Foundation · Mattress Clarity · NapLab. Mattress Clarity and NapLab reviewed the Helix Midnight Luxe by name.

The beds
How is each bed built, and who is it for?
Coil-on-coil innerspring
Saatva Classic
Saatva Classic
The Classic is Saatva's coil-on-coil bed with a 3 in Euro pillow top. Two layers of steel coils sit under the pillow top. It comes in three feels and two heights.
Fire barrier: plant-based thistle, per Saatva
Saatva Classic, Queen, 11.5 in height, as Saatva lists it. Coil counts are the same at every feel. Layer order only, not to scale.
A crew brings it to your room and sets it up for free. You get 365 nights to try it, and a return costs $99. Pick Luxury Firm if you're between 130 and 230 lbs; Sleep Foundation scores it 8.5 to 9 in every position for that weight.
Who may like this bed?
You want it carried in and set up for you.
You want a full year to make up your mind.
You want a Split King in one order for an adjustable base (11.5 in height only).
Who may prefer another bed?
You want a free return; Helix has one after night 30.
You want only one firmness to pick from; Helix sells one feel, Saatva sells three.
You want the lowest price; the Midnight Luxe costs less at every size Helix sells.
The Midnight Luxe puts gel memory foam and dense memory foam over up to 1,000 individually wrapped coils, with extra support under the hips and around the edge. Helix sells it in a single Medium Feel; Sleep Foundation rates that feel 6 out of 10 for firmness.
Fire barrier: a rayon fire barrier, per Helix
Helix Midnight Luxe, Queen, TENCEL cover with the standard Luxe Layer, as Helix lists it. Helix says up to 1,000 coils, not an exact count. Layer order only, not to scale.
It ships free in a box by FedEx, and you set it up unless you pay Helix's In-Home Setup & Removal fee (from $219). You get 120 nights, but you'll need to sleep on it for 30 nights before you can send it back. The return itself is free. Sleep Foundation named the Midnight Luxe its best mattress overall for 2026 and scored it 9.5 to 10 for side sleepers in every weight group.
Who may like this bed?
You want a lower price at every size.
You're a side sleeper; Sleep Foundation scored it highest there.
You want a free return once you're past night 30.
Who may prefer another bed?
You'd rather not carry and unbox a 115 lb bed.
You want a choice of feels; Helix sells the Luxe in one.
You need a split king; Helix doesn't sell one as a single mattress.
What do the brands say about fire barriers, fiberglass and certifications?
Why this matters to you: Every mattress sold in the U.S. must pass a federal open-flame test. Some brands pass it with a barrier made with glass fiber, which can get out if the cover is removed. Know what's inside before it's in your bedroom.
Both brands name a fire barrier and say in writing that it isn't fiberglass. Saatva uses a plant-based thistle pulp; Helix uses a rayon barrier built into a foam layer.
Saatva Classic
Fire barrier: plant-based thistle
Saatva Classic
Saatva says it's "made of wood pulp bonded with a small amount of polyester."
No fiberglass, brand says
Every Saatva mattress
Saatva's FAQ: "We never use fiberglass or toxic chemical flame retardants/barriers in any of our mattresses."
CertiPUR-US foams
The foam layers only
An outside group checked that the foams are made without certain harmful chemicals and are low in emissions. It doesn't cover the coils, cover or barrier.
Helix Midnight Luxe
Fire barrier: rayon, in a foam layer
Helix Midnight Luxe
Helix says every mattress uses "a fire retardant yarn made from a chemical-free Rayon barrier that is in the form of a small foam layer."
No fiberglass, brand says
Every Helix mattress
Helix support center: "No, every Helix mattress is made without the use of fiberglass."
CertiPUR-US foams
All foam in the bed
Helix says every mattress is CertiPUR-US certified.
Check the law tag when it arrives. It lists what the bed is made of. If it doesn't settle the fiberglass question, ask the brand in writing. Never remove a cover that says not to. Why fiberglass in mattresses matters →
Living with it
How do delivery, setup and care compare?
Why this matters to you: A 115 lb box on a stair landing is a different evening from a crew that sets up the bed. These details decide the first night.

The trade-off: Saatva's crew carries the bed in and hauls the old one away for free. Helix ships free by FedEx, but in-home setup and removal costs from $219, and that fee isn't refunded if you later return the bed.

Warranty
Terms checked on each brand's site · Sep 27, 2026
What does each warranty cover, and what voids it?
Why this matters to you: A warranty covers defects, not comfort. Your bed base, stains and how deep a sag is all decide whether a claim is paid.

The trade-off: Helix repairs or replaces the bed at no cost for a full 10 years, then charges a rising percentage of the current price. Saatva's free window is shorter, years 1 and 2, but its year-3-on fee is a flat $149 rather than a percentage.
Both brands cover a dip deeper than 1.5 in, so measure it the same way for either bed.
Strip the bed down to the mattress and wait a few hours so the top layers can recover.
Lay a straight edge (a broom handle or long level) across the dip, resting on the flat parts.
Measure from the edge down to the deepest point, then photograph the ruler for your claim.

Quick Answers
Quick answers before you buy
Which is cheaper, the Saatva Classic or the Helix Midnight Luxe?
The Helix Midnight Luxe, by about $30 for a Queen ($1,874 against $1,904, checked Sep 27, 2026), and it costs less at every other size too.
Which is cheaper to return?
The Helix Midnight Luxe, once you're past night 30. Helix's return is free after that, though a paid setup fee isn't refunded. Saatva takes $99 from your refund but lets you return it any night of the 365.
Which is firmer?
The Saatva Classic's Firm option. Saatva sells Plush Soft, Luxury Firm and Firm; Helix sells the Midnight Luxe in one Medium Feel, which Sleep Foundation rates 6 out of 10.
Does either mattress contain fiberglass?
No, both brands say in writing. Saatva uses a plant-based thistle barrier; Helix uses a rayon barrier built into a foam layer. Check the law tag on either bed.
Which is better for side sleepers?
The Helix Midnight Luxe. Sleep Foundation scored it 9.5 to 10 for side sleepers in every weight group, and named it best mattress overall for 2026.
Does either one arrive in a box?
Only the Helix Midnight Luxe. It ships free by FedEx, and a Queen weighs 115 lbs. A Saatva crew carries the Classic into your room and sets it up for free.
Can I use an adjustable base with either?
Yes, with a limit on the Saatva. Saatva's warranty allows an adjustable base only on the 11.5 in Classic. Helix sells its own Adjustable Base as an add-on.
Can I swap for a different feel?
Only on the Saatva, since Helix sells the Midnight Luxe in one feel. Saatva charges $99 for an exchange. Helix's exchange is free and skips the 30-night wait, but it swaps you into a different Helix model.
