The firmest Estate, stated plainly: a true 9 out of 10
The Estate 14.5" Ultra Firm is the most supportive bed in the tier, and it does not pretend to be anything softer. It is a genuine 9-out-of-10 tight-top built on the IntelliCoil® nested-coil system and a thin layer of TEMPUR-Indulge™ memory foam under a breathable TENCEL™ cover. If you want a flat, rock-solid surface and you mean it, this is the one to lie on first.
What you notice in the first few minutes
Lie down and you stay on top of the mattress, not in it. Hips and shoulders hold their line, the spine stays flat. There is no plush layer to sink through and no soft top to settle into over the first few weeks, so the surface you feel in the showroom is the surface you take home a year from now.
Who actually wants a 9 out of 10
Ultra firm is not for everyone, and that is the point. Stomach sleepers who need their hips held level, heavier back sleepers who bottom out on softer beds, and anyone who has slept best on an old-school firm mattress will recognize this feel in seconds. The tight top puts you in direct contact with the support layer: no cushion to break in, no softness to settle through.
Here is the honest other half. If you sleep mostly on your side, a 9/10 is usually too firm for the shoulder and hip to settle, and you will feel pressure where a softer bed would cradle you. That is not a flaw, it is the wrong tool for that sleeper, and the Mattress Overstock floor will steer you to the Estate Medium or Soft rather than a feel that fights your body every night.
The IntelliCoil® difference
Even at 9/10, this is not a plywood feel. IntelliCoil, Stearns & Foster's coil nested inside a coil, firms progressively under weight, and the thin TEMPUR-Indulge layer relieves surface pressure, so ultra-firm support still has a little give exactly where skin meets mattress. Firm, but engineered, not crude. It is also why heavier back sleepers stay on top instead of bottoming out: the more load the coil sees, the firmer it answers.
Craftsmanship you feel
A breathable TENCEL cover sleeps cool against the tight top, a reinforced edge keeps support running nearly wall to wall, and Stearns & Foster builds it by hand to a precision standard. On an ultra-firm bed, where there is nowhere for flaws to hide, that build quality is the whole story. The reinforced edge matters more on a firm bed than people expect: with no soft top to mask a weak perimeter, the surface stays usable nearly edge to edge, no roll-off for a couple sharing it. The foams are CertiPUR-US certified, and the ventilated build keeps a firm surface cooler than a thick pillow-top.
Living with it over time
One honest note for couples: this is a supportive, steady bed, and it transfers a little more movement than a dense all-foam or heavily pocketed-coil design. If your partner is up and down through the night and you wake easily, that is worth feeling for yourself on the floor before you commit. The trade most ultra-firm sleepers make happily: a flat surface that does not soften or develop a body impression, on a hand-built core that is ready for a platform, a solid foundation, or a compatible adjustable base.
Where it sits in the Estate lineup
If 9/10 is more than you need, the Estate Firm (8/10) is a touch more forgiving, and the Estate Medium (5/10) is the universal middle. See the whole tier in the full Stearns & Foster lineup. Read the steps by how much surface give you want before the support takes over: the Ultra Firm gives almost none, the Medium meets most bodies in the middle.
Ten minutes beats ten reviews
Ultra firm is a love-it-or-not feel, which is exactly why you should lie on it before you commit. The Estate Ultra Firm is on the floor next to the Firm and the Medium so you can feel the steps for yourself, across five Kentucky showrooms (Lexington on Nicholasville Road, Richmond, Georgetown, London, Somerset), no appointment needed. The 90-night trial holds when you buy from a local authorized dealer, free local delivery and setup are usually next business day on in-stock sizes, and the old mattress leaves with the Mattress Overstock team. Because everyone on the floor is paid the same no matter which brand you choose, the guidance you get is honest about whether ultra firm is truly your feel. Lie on it in Lexington this week, then select your size to see the live price.
What makes this mattress different
Ultra Firm, 9 out of 10
The most supportive bed in the Estate tier: a flat, rock-solid tight-top surface for sleepers who want firm and mean it.
IntelliCoil® Support Core
A coil nested inside a coil that firms progressively under weight, so ultra-firm support is engineered, not crude, and heavier bodies stay on top.
TEMPUR-Indulge™ Memory Foam
A thin pressure-relief layer so the firm surface still gives a little exactly where skin meets mattress.
Breathable TENCEL™ Cover
A cool-to-the-touch tight-top cover with no thick pillow layer, so a firm surface still sleeps cool.
Reinforced Edge Support
Support that runs nearly wall to wall with no roll-off, so two people get the whole surface.
Handcrafted by Stearns & Foster
Built by hand to a precision standard: on an ultra-firm bed, where flaws have nowhere to hide, build quality is the whole story.
14.5" Tight-Top Build
A clean tight-top profile at fourteen-and-a-half inches that works on a platform, a solid foundation, or a compatible adjustable base.
90-Night Trial · 10-Year Warranty
Lie on it for 90 nights, backed by the brand's 10-year limited warranty, honored when you buy from an authorized dealer.
Ultra-firm tight-top, layer by layer
The Estate Ultra Firm is maximum support, cleanly built from the surface down. There is no plush stack to settle through, so each layer earns its place:
- TENCEL™ tight-top cover. Breathable and cool to the touch, with no thick pillow layer to trap heat or break in over time.
- TEMPUR-Indulge™ memory foam. A thin pressure-relief layer that takes the harsh edge off a firm surface where skin meets mattress, without adding sink.
- IntelliCoil® support core. Stearns & Foster's coil nested inside a coil. It firms progressively under load, which is why this reads as a true 9 out of 10 and why heavier sleepers stay supported on top instead of bottoming out.
- Reinforced edge and base. A stiffened perimeter keeps support running nearly wall to wall, so the usable surface does not stop short of the edge, on a stable foundation built to sit on a platform, a solid base, or a compatible adjustable frame.
Fourteen-and-a-half inches, ultra firm (9/10), with CertiPUR-US certified foams, backed by the 90-night trial and a 10-year limited warranty.
What's inside a Stearns & Foster
Hand-built around IntelliCoil® (a precision coil inside a coil) under layers of cushioning foam and a tailored quilted cover.
For the sleeper who truly wants firm
Stomach sleepers. The headline fit. A flat, firm surface keeps the hips from sagging below the shoulders, the position where a soft bed throws your lower back out of line all night.
Heavier back sleepers. IntelliCoil firms as load increases, so you stay supported on top of the bed rather than sinking into a hammock, the failure mode of softer mattresses for larger bodies.
Old-school firm lovers. If you have always slept best on a hard mattress and every newer bed feels like quicksand, this is the modern version of that feel, with a thin relief layer so it is firm without being punishing.
Couples who share the edge. The reinforced perimeter gives you the whole surface with no roll-off, so two people are not fighting over the middle. The honest caveat is motion: this steady build transfers a little more movement than a dense foam, so a restless partner is worth feeling for on the floor.
Hot sleepers. A tight top with a breathable TENCEL cover and a ventilated coil core runs cooler than a thick pillow-top that traps heat against your back.
Side sleepers (the anti-fit). A 9/10 is too firm for most shoulders and hips to settle into, so you will feel pressure where a softer bed would cradle you. Look at the Estate Medium (5/10) or Soft instead. The Mattress Overstock floor would rather point you there than sell you a feel that fights your body.

Frequently asked questions
How firm is the Ultra Firm, really?
A genuine 9 out of 10, where 10 is the firmest. It is the firmest bed in the Estate tier, a flat tight-top surface with no plush layer. It is deliberately built for sleepers who want maximum support and mean it.
Is it uncomfortably hard?
Not for the right sleeper. IntelliCoil firms progressively under weight and a thin TEMPUR-Indulge layer relieves surface pressure, so it reads as firm but engineered rather than plywood-hard. Because firm is a love-it-or-not feel, lie on it for ten minutes in your real sleep position to be sure it is yours.
Ultra Firm or the Estate Firm?
The Ultra Firm (9/10) is the most supportive in the tier; the Estate Firm (8/10) is a touch more forgiving. Both are tight-tops on the IntelliCoil core, so the difference is how much surface give you feel before the support takes over.
Who is ultra firm actually for?
Stomach sleepers who need level hips, heavier back sleepers who bottom out on softer beds, and anyone who has always preferred an old-school firm mattress. Side sleepers usually want something softer, like the Estate Medium.
How tall is it, and will my sheets fit?
About fourteen-and-a-half inches in a clean tight-top profile. Standard deep-pocket fitted sheets fit fine; it is worth measuring 14.5 inches against your frame before you buy.
Do I need a special foundation?
No. A sturdy platform, a close-slatted base, a solid foundation, or a compatible adjustable base all work. The reinforced base is built to sit on any of them.
What is the warranty?
Stearns & Foster's 10-year limited warranty against manufacturing defects, honored when you buy from an authorized dealer like the Mattress Overstock floor.
Does it sleep cool?
Yes. The breathable TENCEL cover and tight top sleep cooler than a thick pillow-top, and the ventilated coil core moves air rather than trapping heat against your back.
What is the trial, and what if it is not right?
You get a 90-night trial, the same the brand offers, honored when you buy from a local authorized dealer. If the feel is not right, the Mattress Overstock team exchanges it for store credit toward a bed of equal or greater value (you pay any difference); there is no cash refund. Lying on it in the showroom first is the surest way to land on the right feel the first time.
Can I see it near me?
Yes, it is on the floor next to the Firm and the Medium across five Kentucky showrooms: Lexington on Nicholasville Road, Georgetown, Somerset, London, and Richmond. No appointment needed. Free local delivery, and the old mattress is hauled away.
