Assessed from Mattress Online's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
This is a straightforward, low-cost foam mattress that suits landlords, guest rooms and anyone furnishing on a tight budget. The BS7177: 2008 Source 5 fire certification means it meets the standard required for commercial premises, so it's a practical pick for rental properties and B&Bs. The Ecofoam base is made from 100% recycled foam, a small environmental plus at this price. Yes, at 14cm it's noticeably slimmer than a typical everyday mattress, but the resilient Ecofoam core and Reflex comfort layer give it a firmer, supportive feel that holds its shape. A 100-night trial and 10-year guarantee are generous backing for a mattress starting at £125.00.
Key Features & what's inside
- Ecofoam. A 10cm base layer of Ecofoam made from 100% recycled foam, which means firm, deep-down support from a resilient structure. It's the backbone of the mattress and the reason for its solid feel.
- Reflex Foam. A 4cm top layer of Reflex foam that adds pressure relief, so your hips and shoulders get a little cushioning against the firm base. It also helps the mattress keep its shape over time.

Who's it NOT for?
At 14cm deep, this isn't the mattress for heavier adults or anyone wanting a plush, cradling feel for everyday use. Lightweight side sleepers may also find the Medium to Firm feel slightly too solid on the shoulder. If you want deep contouring or a taller profile, look elsewhere.
Mattress Online Contract Comfort Pro Mattress
How firm is the Mattress Online Contract Comfort Pro?
Mattress Online describes it as Medium to Firm. In practice that means a supportive, fairly solid feel with a little surface cushioning from the 4cm Reflex foam layer, rather than a soft sink-in sensation. Back and stomach sleepers tend to get on best with this kind of feel.
Is the Contract Comfort Pro suitable for rental properties?
Yes, that's arguably its strongest use case. It conforms to BS7177: 2008 Source 5, the fire resistance standard for commercial premises, which makes it appropriate for rentals, guest houses and similar settings where domestic-only certification won't do.
Does the Contract Comfort Pro come with a trial and guarantee?
Bought from Mattress Online's own site, it comes with a 100-night trial and a 10-year guarantee, which is reassuring backing for a mattress priced from £125.00.
How is the Contract Comfort Pro delivered?
Mattress Online lists delivery within 2 to 3 weeks. Delivery to your front door is free, delivery to a room of your choice costs £20, and old mattress recycling is £35.
What sizes does the Contract Comfort Pro come in?
It's available in UK Single, UK Double and UK King, with prices ranging from £125 to £169 depending on size.
