Verdict: The Limited Edition Plush PT 3.0 is for sleepers who want the top of the bed to feel soft and quilted while the base underneath stays steady and full. If you like sinking in just enough at the shoulders and hips without feeling like you are floating on an unsupported cloud, this is the balance Sierra Sleep built here.
How It's Built
This is Sierra Sleep's Limited Edition Plush PT 3.0, Ashley's M452 mattress family, and the name gives away the strategy: pillow top construction stacked in a specific order to land on a plush feel without losing structure. The cover is a Hyper Cool four way stretch knit designed to move with you rather than resist you. Under that sits a layer of high density quilt foam, then a super soft high density support foam that starts the cushioning. Below those two comfort layers is a high density gel memory foam layer, where most of the body contouring happens, followed by another layer of high density plush foam that adds a second, deeper cushioning stage before you reach the base. The foundation is a wrapped coil system reinforced with Ashley Edge support, so the perimeter of the mattress holds its shape even when you sit or sleep near the rail. Altogether the mattress runs about 14.5 inches thick, a real number, not a marketing round up.
Feel and Support
Layering two plush comfort foams over a gel memory foam middle gives this mattress a soft first hand feel that still has somewhere to go when weight comes down: the wrapped coils flex independently under pressure points and spring back, so the mattress does not bottom out the way an all foam plush bed sometimes can. Because the coils are individually wrapped, movement stays localized, so a partner rolling over or getting up in the night is far less likely to travel across the mattress and wake you. It is a genuinely plush mattress, closer to the soft end of the comfort range than the middle, and it reads that way from the first lie down.
Who It Suits
- Side sleepers who want real cushioning at the shoulder and hip without a hard press back
- Combination sleepers who shift positions and want the surface to keep up without waking a partner
- Back sleepers who prefer a softer top layer but still want coil support underneath rather than pure foam
- Anyone replacing an older, worn plush mattress that has lost its lift, since the wrapped coils here are doing real work at the perimeter and underneath the foam
Who Should Look Elsewhere
Stomach sleepers and anyone who wants a firm, minimal sink surface should look at a firmer mattress in the Sierra Sleep line instead, a plush pillow top like this one is built to give, not resist. If you run hot and want cooling beyond a knit cover and a gel layer, ask the floor team about the hybrid cooling options nearby.
Sierra Sleep backs the Limited Edition Plush PT 3.0 with a 10 year non prorated limited warranty, and it ships as a standard mattress, not compressed in a box, so what arrives is exactly what you will sleep on. It is available in Twin, Twin XL, Full, Queen, King, and California King.
Plush is one of those words that means something different to every sleeper, and the only real way to know if this one matches your idea of plush is to lie down on it. Come try the Limited Edition Plush PT 3.0 at any of our Kentucky showrooms and feel the coil and foam balance for yourself before you decide.
What makes this mattress different
A pillow top that means it
Two separate high-density plush foam layers stack above the coils, so the softness at the surface is not a thin quilt trick, it goes deep before you reach anything firm.
Gel memory foam through the middle
A high-density gel memory foam layer sits between the two plush layers, contouring to the shoulders and hips and helping pull heat off the body at those pressure points.
Wrapped coils with reinforced Ashley Edge
The base is an individually wrapped coil system with reinforced edge support, so the perimeter holds its shape when you sit down or sleep near the rail instead of collapsing.
Motion stays where it starts
Because each coil flexes on its own, a partner rolling over or getting up early is far less likely to travel across the mattress and wake you.
Hyper Cool stretch knit cover
The cover is a four-way stretch knit built to move with you and to feel cool to the touch when you first lie down, rather than clingy or plastic.
About 14.5 inches, no box compression
This mattress runs roughly 14.5 inches thick and ships as a standard mattress, not compressed and rolled, so what you unwrap is exactly what you sleep on.
10-year non-prorated warranty
Sierra Sleep backs the Limited Edition Plush PT 3.0 with a 10-year non-prorated limited warranty against manufacturer defects.
Six sizes, one comfort level
Twin, Twin XL, Full, Queen, King, and California King all use the same layer stack, so the feel does not change as the size does.
Two plush layers over gel foam, anchored by wrapped coils
The Limited Edition Plush PT 3.0 is Sierra Sleep's Ashley M452 mattress, and it is built to be plush without going soft all the way to the base. From the top down: a Hyper Cool four-way stretch knit cover, a layer of high-density quilt foam, a super-soft high-density support foam, a high-density gel memory foam layer for contouring and heat pull, and a second high-density plush foam layer for a deeper second stage of cushioning. All of that sits on a wrapped coil system reinforced with Ashley Edge support, so the coils are doing real work at the perimeter and underneath the foam rather than just filling space. Altogether the mattress runs about 14.5 inches.
The result is a bed that leads with softness at the surface, the two plush foam layers and the gel layer are where most sleepers will feel the mattress, while the coils keep the whole thing from bottoming out and add the edge support and motion isolation a pure foam mattress cannot match on its own.

Side sleepers: this is close to an ideal match. The plush foam layers cushion the shoulder and hip, the two pressure points side sleeping loads the most, while the coils keep the spine from sagging out of line underneath.
Combination sleepers: the softness up top is forgiving as you shift positions through the night, and because the coils are individually wrapped, moving around does not create the bounce or transfer that can wake a partner.
Back sleepers who like softer beds: the coil base still lifts the hips and keeps the spine reasonably level underneath the plush layers, so back sleepers who find firm mattresses uncomfortable can do well here.
Couples: the wrapped coil design isolates motion well for a mattress this plush, so one partner getting up rarely disturbs the other.
Anyone replacing a worn-out plush mattress: if your current bed has lost its lift and sags in the middle, the reinforced coil base and edge support here are built to hold that shape longer.
Probably not for you if: you are a stomach sleeper or you generally prefer a firm, minimal-sink surface. A plush pillow top is built to give at the surface, and that is the opposite of what a stomach sleeper's lower back usually needs. Ask the floor team about a firmer model in the same Sierra Sleep line instead.

Frequently asked questions
How firm is the Limited Edition Plush PT 3.0?
It is built as a plush mattress, on the softer end of the comfort range rather than the middle. Two high-density plush foam layers and a gel memory foam layer sit above the coils, so the surface gives noticeably at the shoulders and hips before you feel the firmer support underneath.
What is actually inside this mattress?
From the top down: a Hyper Cool four-way stretch knit cover, a high-density quilt foam layer, a super-soft high-density support foam layer, a high-density gel memory foam layer, a second high-density plush foam layer, and a wrapped coil system reinforced with Ashley Edge support at the base. It runs about 14.5 inches total.
Is this a hybrid mattress or all foam?
It is a hybrid: several foam comfort layers on top of an individually wrapped coil system, not an all-foam build. The coils are what give it real edge support and better motion isolation than a foam-only plush mattress typically offers.
How does it handle motion transfer if I share the bed?
Well for a plush mattress. Because the coils are wrapped individually, each one flexes on its own instead of pulling on its neighbors, so a partner turning over or getting up early is far less likely to travel across the mattress and wake you.
Does this mattress sleep hot?
The Hyper Cool stretch knit cover and the gel memory foam layer are both there to help move heat away from the surface, and that does make a real difference. That said, it is still a foam-forward plush mattress, so a very hot sleeper who wants maximum airflow may want to compare it in person against one of our hybrid cooling models.
How thick is the Limited Edition Plush PT 3.0?
About 14.5 inches, measured on the Queen. It is a full-depth mattress, not a slim or bed-in-a-box style profile, and it ships as a standard mattress rather than compressed and rolled.
Does Mattress Overstock offer an at-home trial on this mattress?
No. Sierra Sleep beds, including the Limited Edition Plush PT 3.0, do not come with an at-home trial period. The way to know if the plush feel is right for you is to lie down on this exact mattress at one of our Kentucky showrooms before you buy, in whichever sleep position you actually use at home.
What warranty comes with this mattress?
Sierra Sleep backs the Limited Edition Plush PT 3.0 with a 10-year non-prorated limited warranty covering manufacturer defects.
What sizes does this mattress come in?
Twin, Twin XL, Full, Queen, King, and California King. All sizes share the same layer stack and comfort level, so the feel is consistent whichever size you choose.
