Englander firm: classic spinal support, modern build quality.
The Englander Amesbury Firm Mattress is a firm innerspring mattress built for back and stomach sleepers, and plus-size sleepers. It pairs a quality comfort system with a responsive support core for nightly support that doesn't pack down. At 14.5", it sits in the premium profile range — generous enough for adjustable bases yet still easy to sheet.
- Back and stomach sleepers
- Plus-size sleepers needing lift
- Sleepers with chronic lower-back pain
- Hot sleepers (less foam to trap heat)
- Side sleepers under 150 lb (shoulder pressure)

A foam-encased perimeter lets you use the full sleep surface — and sit on the edge to dress.
A reinforced center third keeps the spine aligned across every position.
A tall comfort and support stack means more contour up top and stronger lumbar push-back below.

About this mattress
Englander Amesbury Firm 14.5" Mattress
The Amesbury Firm is the entry point to the Englander lineup, delivering firm innerspring support at an accessible $1,199 Queen. Englander has been building mattresses since 1894 — over 130 years of continuous American manufacturing. The Amesbury carries that heritage in a straightforward, no-frills firm mattress that does its job without pretending to be something it is not.
What Makes the Amesbury Firm Different
The Amesbury Firm uses a traditional innerspring coil system with a firm comfort foam surface. At 14.5 inches, it provides a substantial profile without the complexity of hybrid or memory foam construction. The firm comfort level sits at approximately 7-8 on a 10-point scale, making it one of the more supportive options in the Englander entry-level range. The coil system provides responsive bounce and natural airflow through the mattress core — advantages that all-foam mattresses cannot match at this price point. CertiPUR-US certified foams ensure the comfort materials meet strict standards for content, emissions, and durability. The mattress is adjustable base compatible, so you can pair it with an adjustable frame without voiding the warranty.
Construction
- Premium Fabric Cover — A breathable, durable cover with quality stitching
- Firm Comfort Foam — A thin, firm foam layer provides surface comfort without sacrificing support. CertiPUR-US certified.
- Transition Foam — Progressive support layer bridges comfort foam with the coil system below
- Innerspring Coil System — Traditional coil support with responsive bounce, natural airflow, and consistent support across the full surface
- Edge Support — Foam-encased perimeter provides edge-to-edge stability and a firm seating edge
Who the Amesbury Firm Is Best For
Back sleepers get the flat, firm surface needed for neutral spinal alignment. The innerspring system prevents hip sinking that causes lower back strain. Stomach sleepers benefit from the firm surface that keeps the midsection from dropping below alignment. Budget-conscious buyers who want genuine Englander heritage quality without moving up to the Cambridge or Everest price tier will find the Amesbury Firm delivers real value. It is also an excellent choice for guest bedrooms where you want quality without overspending.
