Mattresses in Butte, Montana — The Sleep Floor

Firmness on a label means nothing.

What matters is how your shoulders and hips settle in at two in the morning. There is no way to know that from a screen, which is why we do this in person.

The first question

Two lines. One decision.

Dura-Last by Spring Air Plush Pillow Top (Model 7668) mattress, three-quarter view on white background
Traditional coil

Dura-Last by Spring Air

An encased-coil mattress where the only decision is how firm. Four steps from Extra Firm to Plush Pillow Top, on the same 8.5-inch five-zone coil unit.

The only line we carry that comes in Full.

Comfort technology

Qube by Sound Sleep

Built in Lacey, Washington. Here the decision is not budget, it is feel: whether you sleep on a mattress or sink into it. Built for adjustable bases.

Within a tier, the models are the same price. You get fitted between them, not upsold.

The Dura-Last ladder

Four steps. One coil unit.

Every Dura-Last sits on the same 8.5-inch five-zone encased coil. What changes as you go up the ladder is what is on top of it — and that is the only thing you are actually choosing between.

What is actually inside

The part you cannot feel in ninety seconds.

Spring Air publishes the layer construction for every model. Worth a look before you come in, because it tells you where the money goes — and it is the fastest way to see why two mattresses at similar prices feel nothing alike.

The Qube pair

Same price. Opposite feel.

Indulge and Immerse cost exactly the same in every size. You are not choosing a budget here, you are choosing whether you want to sleep on a mattress or in one — and the layer diagrams below show you why they feel nothing alike.

Qube Indulge (Model 1401) shown in cross-section with its layers labelled: Plush Foam, Talalay Latex Foam, Qube GelShell Support System, Medium Response Foam and 5-Zone Support Core
Sleep on it

Qube Indulge

Talalay latex over the GelShell system makes it responsive and buoyant. You sit on top of the surface rather than settling into it, and it pushes back when you move.

  • Model1401
  • Twin XL$2,799
  • Queen$3,299
  • King$3,999
  • Warranty20 years

Best if you change position often, or if memory foam has ever felt like it was holding on to you.

Qube Immerse (Model 1400) shown in cross-section with its layers labelled: Ultra HD 5 lb memory foam, Qube GelShell Support System, MicroPur Serene, Gel Memory Foam and 5-Zone Support Core
Sleep in it

Qube Immerse

Ultra HD 5 lb memory foam and gel memory foam contour to you and stay there. It spreads pressure rather than resisting it, which is the point if your shoulder or hip is what wakes you.

  • Model1400
  • Twin XL$2,799
  • Queen$3,299
  • King$3,999
  • Warranty20 years

Best if you sleep mostly in one position, or wake with a pressure point rather than a bad back.

Both share the Qube GelShell Support System and the 5-Zone Support Core, both are CertiPUR-US certified with a Qube count of 1116, and both carry a 20-year warranty. Twin XL, Queen and King only — there is no Full and no California King in the Qube line. Layer diagrams supplied by Qube.

Built for a base that moves

This is the part the showroom floor hides.

Every Qube is built to flex on an adjustable base. If you have ever wondered whether raising the head of the bed would settle your reflux, or whether lifting your feet would take the ache out of your legs by morning, this is the line that lets you find out without wrecking the mattress.

We do not stock every base configuration on the floor. Tell us at the fitting that a base is on your mind and we will work through what actually pairs with what, rather than selling you a mattress now and a surprise later.

Qube Indulge (Model 1401) mattress articulated on an adjustable base, head and foot raised

CuAtomic no. 29
The Butte coincidence

This town was built on copper. So is your mattress.

Copper-infused memory foam runs through the line at different depths — half an inch in the Dura-Last Medium and Plush Pillow Top, an inch and a half in the Signature IQ, two and a quarter in the Distinction IQ. Copper pulls heat away from the body instead of trapping it, which is why you stop waking up hot at three in the morning.

We didn’t plan the joke. We just sell it a mile from the pit it came out of.

Signature tool

Sleep Match

Three questions and a size. It gives you the real model, the real price and what is actually inside it — then you come and lie on it.

1 · Which feel are you after?

2 · How firm?



3 · What size?



These are our real prices, not a range. What this cannot tell you is which one your shoulders and hips agree with — that is the thirty minutes.

The honest math

Nine cents each, per night.

Going from our entry queen to a Qube sounds like tripling your money. Spread across the warranty period, for two people, it is eighteen cents a night. Nine cents each.

Cost spread across the warranty period. A warranty term is a coverage period, not a guarantee of how long a mattress will last.

On purpose

We don’t sell mattresses online.

You can buy a mattress in a box from a website. We won’t sell you one that way, because a mattress does not work unless it fits the body lying on it.

Two people rarely need the same thing. If someone else sleeps on this bed, book a time you can both make — testing it together is the difference between deciding today and coming back next week.

And within a Qube tier the models cost exactly the same, so there is nothing for anyone to gain by steering you. There is only the right one and the wrong one.

So we do it the slow way. You come in, you lie down, and you find out.

Thirty minutes, and you know.

Questions

Mattresses, answered

Dura-Last is a traditional encased coil, so the question is simply how firm you want it — Extra Firm, Firm, Medium or Plush Pillow Top, all on the same coil unit. Qube is comfort technology built for adjustable bases, and there the question is feel rather than budget: Indulge is responsive and buoyant so you sleep on it, Immerse contours so you sleep in it. Most people know which camp they are in within about a minute of lying down.

Because they are not better and worse, they are different. Within a tier the price is identical, so nobody here has anything to gain by pushing one over the other. That is deliberate, and it is the reason the fitting is a fitting rather than a sales pitch.

Copper conducts heat away from the body rather than trapping it. It appears at different depths through the line — half an inch in the Dura-Last Medium and Plush Pillow Top, two and a quarter inches in the Distinction IQ. If you wake up hot, this is the part of the spec sheet that matters to you.

Only in Dura-Last. Qube is made in Twin XL, Queen and King — there is no Full and no California King in that line. If you need a Full, the choice is which Dura-Last firmness.

No, and we would rather say so. A warranty is a coverage period against defects, not a promise of lifespan. We quote cost per night across the warranty period because it is a fair way to compare two mattresses, not because we are predicting how long yours will last.

Qube is built for it. If an adjustable base is part of your plan, say so when you book and we will set the fitting up accordingly.
