Sierra Sleep by Ashley
Sierra Sleep Nectar Foam Kids Mattress
Couldn't load pickup availability
The Sierra Sleep Nectar Foam Kids Mattress is built for a child moving out of a toddler bed and into their first real one, and it is honest enough to say so right on the cover: one long side reads Nectar Kids 3 to 7, the other reads Nectar Kids 8 to 12. Flip it as your child grows and the mattress adjusts with them, instead of a bed sized for their fifth birthday that you are still hoping feels right by their eleventh.
How it is built
This is Ashley's Nectar Foam Kids model M117, an 8 inch all foam mattress with no springs and no coils inside. A comfort layer sits over a supportive foam base, and the whole thing is wrapped in a soft, quilted fabric cover with the two age labels sewn into opposite long sides so you always know which face is up. Because there is no coil unit to work around, the mattress ships compressed and needs no assembly. Twin and Full both arrive ready to unbox onto a bed frame, a bunk, a trundle, or a guest room floor for a sleepover.
Feel and support
All foam construction has real upside in a kid's room. There is nothing inside to creak, shift, or squeak under a restless sleeper, and the foam contours gently rather than pushing back hard, which tends to suit a lighter body better than an adult firmness mattress does. The reversible cover is the more interesting piece of the design: the 3 to 7 side and the 8 to 12 side are built around different stages of a growing child, so instead of buying a whole new mattress the year your child outgrows the first setting, you flip the same one over. Between the flip and the simple, low drama foam build, this is a mattress meant to be lived on hard by a kid, not treated delicately.
Who it suits
- A child moving from a crib or toddler bed into a Twin or Full for the first time
- Bunk, loft, and trundle setups where a coil mattress is heavier and bulkier than it needs to be
- Parents who want one mattress to carry a child from around age 3 through 12 rather than swapping it out partway there
- A guest room or grandparents' house bed that occasionally hosts visiting kids
It is probably not the right pick if you are furnishing a room for a teenager who has already grown past the 8 to 12 side, or if you specifically want the bounce of a coil based innerspring feel. This is a foam mattress designed around a kid's changing body over several years, not a scaled down adult bed.
Available sizes
- Twin
- Full
A waterproof mattress protector under the fitted sheet is worth adding on day one, both for nighttime accidents and to keep the cover looking new through years of jumping, reading in bed, and everything else a kid's mattress absorbs. The best way to know if the fit is right for your child is to come feel both sides of it yourself: stop by one of our Kentucky showrooms and lie down on the actual mattress before it goes home with you.
What makes this mattress different
A cover that flips as your child grows
One long side is stitched Nectar Kids 3 to 7, the other Nectar Kids 8 to 12, so the same mattress can move from a toddler's first big bed into the years right before a teenager, no cover swap needed.
8 inch all foam build
A supportive foam base under a foam comfort layer, with no coils and no springs anywhere in the construction.
Ships compressed, no assembly
Because there is no coil unit to unpack, the mattress arrives compressed in a box and needs no tools or setup, just unroll it onto the frame.
Quiet under a restless sleeper
An all foam interior has nothing to creak or shift, so a kid who tosses and turns will not wake themselves up with mattress noise.
Gentle contouring for a lighter body
The foam responds to a child's lighter weight with a softer give than the same foam would offer under an adult, without losing support underneath.
Built for bunks, lofts, and trundles
The compact, coil free build is easier to carry up a staircase or lift into a bunk or loft frame than a traditional innerspring mattress the same size.
Soft, quilted fabric cover
A quilted fabric surface wraps the whole mattress, finished with the age range label sewn into each long side.
Twin and Full sizing
Available in Twin for a first big kid bed and Full for a room that needs to fit a bit more or host a sleepover.
One mattress, two stages of a growing kid
The Nectar Foam Kids Mattress, Ashley model M117, keeps its construction simple on purpose: a foam comfort layer over a supportive foam base, wrapped in a quilted fabric cover, at an 8 inch total profile. There are no coils or springs anywhere inside, which is what lets the whole mattress compress for shipping and skip assembly entirely.
The detail that sets this one apart is stitched right into the cover. One long side reads Nectar Kids 3 to 7, the other reads Nectar Kids 8 to 12, and the two sides are built to different support needs for those stages. Flip the mattress over as your child grows instead of replacing it, and you get years of use out of one purchase rather than two.
Twin and Full share the same build, the difference is footprint, not feel. Both fit standard bed frames, bunks, lofts, and trundles without a box spring.
See the full Sierra Sleep lineup →Matched to a kid's stage, not just their size
Ages 3 to 7: the labeled 3 to 7 side is built for a lighter, still growing body, offering gentle contouring without the mattress swallowing a small child.
Ages 8 to 12: flip to the 8 to 12 side as your child gets bigger and heavier, for a support level built around a kid who has outgrown the first stage.
Bunk and loft sleepers: the coil free, compressible build is noticeably easier to carry up a ladder or into a loft frame than a traditional spring mattress the same size.
Restless or active sleepers: an all foam interior has nothing to creak or shift, so a kid who moves around at night is less likely to wake themselves up.
Guest room and grandparents' house beds: a Twin or Full that only sees occasional use from visiting kids, without paying for features a full time bed needs.
Probably not for: a teenager who has already grown past the 8 to 12 side, or a family that specifically wants the bounce of a coil based innerspring feel.

Frequently asked questions
Is the Nectar Foam Kids Mattress memory foam or a hybrid?
All foam, no coils and no springs. A foam comfort layer sits over a supportive foam base at an 8 inch total profile, which is also what allows it to ship compressed and skip assembly.
What does the 3 to 7 and 8 to 12 label on the cover mean?
The cover is built with two sides for two stages: one long side is labeled Nectar Kids 3 to 7, the other Nectar Kids 8 to 12. As your child moves from one age range into the next, you flip the mattress instead of replacing it.
Do I need a box spring or foundation?
No. The all foam build works on a standard bed frame, platform, bunk, loft, or trundle without a box spring underneath.
Is this mattress noisy?
No. With no coils inside, there is nothing to creak or shift, so a restless kid will not wake themselves up with mattress noise the way an old spring mattress can.
What sizes does it come in?
Twin and Full. Twin suits a first big kid bed, bunk, or loft frame, and Full gives a bit more room or works well for sleepovers.
Does Mattress Overstock offer an at-home trial on this mattress?
No. Sierra Sleep beds like this one do not include an at-home trial period. The honest way to know if the feel is right for your child is to visit one of our Kentucky showrooms and try it in person before you buy.
Can I see this mattress in person near me?
Yes, and with a kids 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. Bring your child in to feel both sides of the cover before you choose a size.
