The Ambrose is our basic “kid bed” in the BackSense line. It’s a thinner mattress with simple comfort foams over a real innerspring, so kids and lighter sleepers get proper support without a lot of extra height or cost. We use it most often on bunk beds, trundles, RV’s and starter beds where you want something better than a cheap promo mattress, but you’re not trying to build a high-end adult sleep setup.

Overview / description
The BackSense Ambrose is our entry-level mattress, and we mainly treat it as a kid bed or light-use option. It has a thinner profile and a straightforward construction: basic quilt foams on top, a firm insulator, and a traditional innerspring core for support. It’s a clear step up from the “mattress-in-a-box for $99” type products, but it’s not meant to compete with the thicker, more cushioned models in the rest of our lineup. If you need something decent for a child’s room, bunk, trundle, RV or occasional guest space and don’t want to overspend, this is where we start.
Best for
Kids and younger teens who don’t need a thick, heavy-duty mattress yet
Bunk beds, trundle beds, daybeds, and tight spaces where height matters
Occasional-use guest rooms, lake cabins, or spare rooms on a budget
Not our first choice as an every-night mattress for larger or heavier adults
Key features
Simple, kid-friendly build: basic comfort foams over a supportive innerspring
Thinner profile that fits safely in many bunk and loft-bed rails
Feels “firm with a bit of cushion” rather than super soft or squishy
A good starting point if you want a real mattress without jumping into mid-range prices
Construction & specs
Comfort & quilt layers
Quilted stretch-knit cover with a thin layer of soft fiber for a smoother surface
Modest amount of polyurethane quilt foam for a bit of cushion without making the bed thick or mushy
Transition / upholstery
Simple polyurethane upholstery pad over the springs to even out the feel
Firm insulator layer to help protect the foams from the coils underneath
Support system
Pocketed innerspring unit
Built to feel stable for kids and lighter sleepers without a lot of motion transfer for the size/price

Common kid and guest sizes: Twin, Twin XL, Full, Queen
Foundation & compatibility
Works on standard rigid foundations, bunkie boards, or slatted bunk frames with proper spacing

Mattresses to help you sleep well and live better.
