Mattress Online

About Mattress Online

Mattress Online was founded in 2003 by Steve Adams and Steve Kelly, two of the earliest pioneers of selling mattresses and beds online at a time when almost no one else was doing it. From a first website carrying just five products, the business has grown into one of the UK's leading mattress retailers, based in Rotherham, South Yorkshire, and built on a reputation for fast, reliable delivery and genuine sleep expertise.

Over two decades the brand has delivered more than one million mattresses and earned a strong following, reflected in over 65,000 Trustpilot reviews with an average rating of 4.8 out of 5. Mattress Online has been named the National Bed Federation's Online Bed Retailer of the Year four times, and works to high industry standards across its product range, with the majority of its wider catalogue approved by the National Bed Federation.

The Mattress Online own-brand range available at Rackhams reflects that experience, covering memory foam, pocket spring and orthopaedic mattresses in firmness levels from medium through to extra firm, and sizes from single to super king. Beyond the products themselves, Mattress Online is known for its sleep-focused ethos and its charity work, including long-standing partnerships with The Sleep Charity and Zarach, an organisation dedicated to ending child bed poverty.

Frequently Asked Questions about Mattress Online

What types of Mattress Online mattresses are available at Rackhams?

The Mattress Online range at Rackhams includes memory foam, pocket spring and foam mattresses across the Classic Gold, Memory Zone and Rock Hard collections. Options span orthopaedic and firm support designs, with the Memory Zone range offering 1000, 2000 and 3000 pocket spring counts and the Rock Hard range offering super firm, mega firm and ultra firm support.

What is the difference between pocket spring and memory foam mattresses?

Pocket spring mattresses use individual springs that move independently, adapting to the body and offering targeted support with good airflow. Memory foam mattresses mould to the body's shape, relieving pressure points and minimising movement transfer, which is useful when sharing a bed. The Mattress Online Memory Zone range combines pocket springs with a memory foam comfort layer to offer both.

What is an orthopaedic mattress?

An orthopaedic mattress is designed to provide firmer, more structured support, particularly for the back and joints. The Mattress Online Classic Gold Ortho and Rock Hard ranges at Rackhams fall into this category, offering firm to extra firm support suited to those who prefer a harder sleep surface or need additional support.

What firmness should I choose?

Firmness is a matter of personal preference and sleeping position. Firmer mattresses such as the Rock Hard range suit those who prefer minimal give or sleep on their back or front, while medium options offer a balance of support and cushioning. Side sleepers often prefer a little more give to cushion the shoulders and hips. Check individual product listings for the firmness rating of each mattress.

Mattress Online mattresses at Rackhams are available in standard UK sizes including single, small double, double, king and super king. Available sizes are listed on each individual product page.
