What's inside
Bamboo quilting - a deep, plush surface that sleeps cool and helps wick away moisture. *can be spot cleaned, but we do recommend a waterproof protector.
Copper Foam™ - naturally antimicrobial, draws the body heat away. Plush and contour without the memory foam, sink in or overheating. This is the same eco-friendly material found in our upper level Havens.
808 zoned pocket coils - Like a premium adult mattress, the Junior is zoned firmer under the hips, gentler at the shoulders. This aids in proper spine alignment. ideal to support growing bodies.
Updated yarn with more LYCRA™ — a cover that stretches and recovers instead of bunching.
Is Junior right for my child?
Junior is designed for roughly ages 5 to 16, for kids who've outgrown their first bed and are heading into growth spurts. It's 8.5" and hybrid, with real coils underneath. For toddlers, top bunks and trundles, Haven also makes a lower 6" all-foam mattress, Haven Kids.
Specs & compatible frames
Height 8.5". Works on platforms, slats, adjustable bases and box spring foundations. Bunk-safe where the guard rail sits above the mattress surface. Check frame manufactures for details.
Twin 39" × 75" · Twin XL 39" × 80" · Double/Full 54" × 75". Ships compressed and boxed.
01 — Three details you can feel
Softer on top. Serious underneath.
Press a hand into it and you'll feel it before you read a word.
Detail 02 · Comfort layer
Copper Foam™
Copper is naturally antimicrobial and conducts heat away from the body. Built into the foam, so it never washes out.
Detail 03 · Cover
Cooling yarn with more LYCRA™
A stretch-knit cover flexes with the foam and the sleeper, then snaps back. No bunching, no sagging fabric: it holds its shape through years. We do not condone "monkeys jumping on the bed".
02 — Zoned for a body that keeps changing
808 coils. Three jobs.
Over 40% of a sleeper's weight sits at the hips. Junior's coil system is firmer there and gentler at the shoulders, so the spine stays level whether your kid is 45 lb or 145. Hover or tap a zone.

Zone 1 — Shoulders
Room to sink, a little
Softer coils let the shoulder settle into the quilt instead of propping it up. It's the difference between a side sleeper who wakes rested and one who wakes with a numb arm.
Zone 2 — Hips & lower back
Where the weight lands
Firmer, denser coils stop the hips from dropping, which is what keeps a growing spine straight through the night. It's the part of a kid's bed that gives out first, and the part Junior reinforces most.
Zone 3 — Legs
Easy on the knees
Gentler coils under the legs reduce pressure behind the knees and ankles. Because every coil is individually wrapped, a 2 a.m. roll-over doesn't travel across a sleepover.

03 — Why copper, in a kid's bed
Spilled juice. Sweaty Julys. The dog. A surface that fights back.
Copper is one of the oldest antimicrobial materials we know; it's why hospitals use it on bed rails and door handles. In Junior's Copper Foam™ it does two quiet jobs every night: it helps resist the bacteria, mould and odour that build up in a kid's mattress, and it pulls heat away from a sleeper who runs hot.
Naturally antimicrobial
Helps limit bacteria, mould and mildew growth inside the mattress, so it stays fresher between sheet changes.
Conducts heat away
Copper is highly thermally conductive. It moves body heat out of the foam instead of storing it.
Never washes out
The copper is part of the foam itself, not a spray or a treatment, so it lasts the life of the bed.

04 — The years it's built for
Ten years is a long time in a kid's life.
The warranty is ten years. So is the stretch of childhood Junior was designed to cover.
-
Age 6
The "real bed" night
Out of the toddler bed and into something that feels like yours. Softer surface, easy to climb into.
-
Age 9
Sleepover HQ
Two kids, one bed, a lot of whispering. Pocket coils keep one roll-over from waking the other.
-
Age 12
The growth spurt
Four inches in a year, growing pains at night. The zoned hips hold alignment while everything else is changing.
-
Age 16
Still theirs
Homework, headphones, a basketball by the bed. Copper keeps it fresh, and the coils haven't softened into a hammock.
05 — Fits the room they have
A real mattress. Still built for kids' furniture.
At 8.5", Junior sits like a proper mattress on a standard frame without swallowing a small room, and it still fits most of the furniture a kid's bedroom already has.
Platforms, slats & adjustables. Every standard frame, box spring foundation included.
Most bunks and lofts. Check the guard rail clears the surface by 5". If it doesn't, our lower 6" Haven Kids is the safer pick up top.
Daybeds & captain's beds. Twin and Twin XL drop straight into most drawer frames.
Standard sheets fit. Any regular-depth Twin, Twin XL or Double sheet set. No deep-pocket hunting.

What age is Junior for?
Roughly 6 to 16, from the first "real bed" through high school. For children under six, top bunks or trundles, Haven also makes a lower 6" all-foam kids' mattress. If your child is in between, choose Junior: it's the one they won't outgrow.
Is copper safe for my child to sleep on?
Yes. Copper is a naturally occurring mineral, and in Junior it's bound into a CertiPUR-US® certified foam layer beneath the quilted cover, not a coating your child touches. It's the same reason copper is used on hospital surfaces and in water pipes.
Is "softer" still supportive enough for a growing spine?
The softness is in the quilted surface, the top inch or so. Underneath, 808 pocket coils do the supporting, and they're zoned firmer through the hips where most of the body's weight sits. Comfort on top, alignment below.
Can it go on a bunk bed?
On the bottom bunk, always. On top, measure first: the guard rail should sit at least 5" above the mattress surface. Most bunks rated for mattresses up to 9" are fine; if yours isn't, Haven Kids at 6" is the safer choice.
Do I still need a protector if the foam is antimicrobial?
Yes. Copper helps with what builds up inside the mattress over time; a waterproof protector handles what gets spilled on it tonight. It also keeps the 10-year warranty intact, and it's included in the Complete Sleep Bundle.
How soon can they sleep on it?
The same night. It ships compressed, unrolls in minutes and reaches full height within hours. Ultra low-VOC materials mean there's no chemical smell to air out first.
