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.

Two lines. One decision.

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.
- Warranty10 years
- Queen from$999
- SizesTwin XL · Full · Queen · King
- Made inUSA · CertiPUR-US
The only line we carry that comes in Full.
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.
- Warranty20 years
- Queen from$3,299
- SizesTwin XL · Queen · King
- Made inUSA · CertiPUR-US
Within a tier, the models are the same price. You get fitted between them, not upsold.
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.




Queen pricing. Twin XL, Full and King priced accordingly — Dura-Last is the only line we carry in Full.
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.




Construction diagrams supplied by Spring Air. Made in USA and CertiPUR-US certified, with a 10-year warranty across the line.
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.

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.

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.
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.

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.
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.
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.
We don’t mark it up so we can mark it down.
Qube publishes its suggested retail at qubesleep.com. That is not our number, it is theirs, on their own website, and you can check it in thirty seconds from the parking lot.
Queen pricing. Suggested retail as published by Qube. Twin XL and King priced accordingly.
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.
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.
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.
Yes — Anaconda, Deer Lodge, Whitehall, Boulder, Twin Bridges, Philipsburg and Dillon. Call ahead and we will have the floor ready before you make the drive.
Lie on it before you buy it.
Thirty minutes, free, no obligation. If two of you sleep on it, book a time you can both make.
