The verdict: if you want a mattress that hands you a genuinely soft, cushioned top layer and still keeps real coil support waiting underneath, the Sierra Sleep Limited Edition Plush Mattress is a straightforward way to get both, without paying for extra features you do not need.
How it's built
This is Ashley's Sierra Sleep M411 platform, the original entry in the brand's long running Limited Edition Plush lineup. The surface starts with a soft, 4 way stretch knit cover, a fabric built to move with your body instead of resisting it. Underneath that cover sits a layer of plush comfort foam paired with gel infused memory foam, the combination responsible for the give you feel the moment you lie down. The gel infusion is there to help pull heat away from the foam, so a soft top layer does not turn into a warm one halfway through the night. Below the foam, a wrapped coil support system carries the actual structure of the mattress, with reinforced edge support built into the perimeter so the sides hold their shape when you sit down to tie your shoes instead of folding in underneath you. Ashley backs the build with a 10 year non prorated manufacturer warranty, and the mattress ships compressed in a box, which makes it easier to carry through a stairwell or a tight apartment hallway than a traditional bed delivered flat.
Feel and support
Plush means plush here. Your shoulders and hips are meant to settle into the comfort foam first, while the wrapped coils underneath do the work of keeping your spine from sagging out of line once you are through that top layer. That combination, soft where you land and supportive where it counts, is what separates a coil based plush mattress from an all foam design that can feel like sinking into a single slab. Individually wrapped coils also flex somewhat independently of one another, so movement on one side of the bed does not travel across the whole surface the way it would on an older style innerspring unit, though any coil based hybrid will still carry a bit more motion than a dense all foam mattress.
Who it suits
- Side and combination sleepers who want real cushioning at the shoulder and hip without losing spine support underneath
- Sleepers replacing an old, worn out plush mattress who want that same soft top layer with fresh materials and a sturdier edge
- Anyone who runs warm and prefers a mattress built around coils rather than a thick slab of dense foam holding heat against the body
- Guest rooms, primary bedrooms, or a first apartment, since compressed shipping makes this an easy mattress to move into tight spaces
Who should skip it
If you are a committed back or stomach sleeper who wants to feel like you are resting on top of the mattress rather than settling into it, a plush comfort layer this soft will likely leave your lower back without enough lift. And if you or a partner are light sleepers who wake at the smallest shift, an all foam mattress will isolate motion more completely than any coil based hybrid, this one included.
The Sierra Sleep Limited Edition Plush Mattress comes in Twin, Twin XL, Full, Queen, King, and California King, all built to the same construction, so the feel stays consistent no matter which bedroom it lands in. Numbers on a page only tell you so much about what plush actually feels like under your own body. Come lie down on this exact mattress at one of our Kentucky showrooms, in your own sleep position, before you decide.
What makes this mattress different
A genuinely plush top layer
Plush comfort foam and gel infused memory foam let your shoulders and hips settle in on contact, the cushioned feel this Sierra Sleep line is named for.
Gel infused memory foam
The gel infusion is built to pull heat away from the foam, so a soft top layer does not turn into a warm one partway through the night.
Wrapped coil support underneath
A full wrapped coil system carries the structure of the mattress, keeping your spine level even as the comfort layer softens around you.
Reinforced edge support
The perimeter of the coil unit is reinforced, so the sides of the mattress hold their shape when you sit down instead of caving in.
Soft, 4 way stretch knit cover
A stretch knit cover moves with your body rather than resisting it, adding to the plush feel right at the surface.
10 year non prorated warranty
Ashley backs the Limited Edition Plush with a 10 year non prorated manufacturer warranty.
Ships compressed in a box
Compressed packaging makes this mattress easier to carry up a stairwell or through a tight hallway than a traditional flat delivery.
Consistent across every size
Twin through California King share the same layered construction, so the feel is the same whether it lands in a guest room or a primary bedroom.
A plush comfort layer over a full coil support system
The Limited Edition Plush starts at the surface with a soft, 4 way stretch knit cover, a cover meant to move with you instead of holding its shape against you. Below that sits the comfort layer: plush comfort foam paired with gel infused memory foam, the pairing that gives the mattress its soft, sink in feel and helps pull heat away from the body at the same time.
Underneath the foam is a wrapped coil support system, the part of the build responsible for keeping your spine level once you settle past that top layer. A reinforced edge runs around the perimeter of the coil unit, so the sides of the mattress hold their shape under a seated sleeper instead of collapsing the way older plush mattresses tend to at the edge.
This is Ashley's original M411 platform in the Sierra Sleep Limited Edition Plush lineup, backed by a 10 year non prorated manufacturer warranty and shipped compressed in a box for easier delivery into tight spaces.

Side sleepers: the plush comfort foam and gel infused memory foam cushion the shoulder and hip, the two spots a side sleeper needs the most relief.
Combination sleepers: the soft top layer gives enough room to move between your side and back through the night, while the wrapped coils keep your spine from sagging out of line in either position.
Sleepers replacing an old plush mattress: if you already know you like a soft, cushioned bed and just need fresh materials and a sturdier edge than your last one had, this is a straightforward upgrade.
Warm sleepers: the gel infused memory foam and the airflow that comes naturally from a coil base help keep this plush build from trapping heat the way a dense all foam mattress can.
Guest rooms and first apartments: compressed shipping makes this an easy mattress to move into a smaller space, and the consistent construction across sizes means it sleeps the same in a spare room as it does in a primary bedroom.
Probably not for you if: you are a committed back or stomach sleeper who wants a firmer surface to rest on top of, or you and a partner are light sleepers who wake at the smallest movement, since a coil based hybrid will always carry a bit more motion than an all foam design.

Frequently asked questions
What does "plush" mean on this mattress?
It means the top layer is genuinely soft. Your shoulders and hips settle into the plush comfort foam and gel infused memory foam instead of resting on top of a firm surface. Underneath that give, a wrapped coil system keeps your spine from sagging out of line, so plush describes the feel of the surface, not a lack of support.
What is the Sierra Sleep Limited Edition Plush Mattress made of?
From the top down: a soft, 4 way stretch knit cover, then plush comfort foam and a layer of gel infused memory foam, then a wrapped coil support system with reinforced edge support around the perimeter. It is backed by a 10 year non prorated manufacturer warranty.
Is this mattress a hybrid or all foam?
Hybrid. The comfort layers are foam, but the support underneath comes from a full wrapped coil system, not a foam core. That combination gives you a plush top with the airflow and responsiveness a coil base provides.
Who is this mattress best suited for?
Side and combination sleepers who want real cushioning at the shoulder and hip, and anyone replacing an old plush mattress who wants that same soft feel with fresh materials. Committed back and stomach sleepers who prefer a firmer surface will likely find this comfort level too soft.
Does this mattress sleep hot?
The gel infused memory foam is built to pull heat away from the body, and the coil base allows more airflow than a thick slab of dense foam would. It is not a dedicated cooling mattress, but the construction works in your favor if you tend to run warm.
What sizes does it come in?
Twin, Twin XL, Full, Queen, King, and California King. Every size shares the same layered construction, so the feel is consistent whether it is going into a guest room or a primary bedroom.
How does delivery work, and is there an at home trial?
Sierra Sleep mattresses do not include an at home trial period. The honest way to know if a plush hybrid like this is right for you is to lie on it yourself, in your own sleep position, on our showroom floor before you buy, rather than guess at home and hope it works out.

Yes, and with a mattress that is genuinely the better way to decide. Mattress Overstock is a Kentucky owned company with showrooms in Lexington, Georgetown, Somerset, London, and Richmond. Come lie on this exact Limited Edition Plush mattress in your own sleep position before you commit to it.
