All Foam Eco Mattress

Quick answer

Choose the All Foam Eco Mattress when you want an economically priced foam mattress with a clear, uncomplicated specification. It combines a Coolmax cover with 9 inches of premium medium-firm foam, a double-sided design and a 3-year warranty, with the Single starting below £100.

The Eco Mattress is intentionally different from the deeper premium memory foam mattress range. It uses one straightforward foam construction rather than separate memory foam and support layers. That makes it easier to compare if your priority is an affordable foam mattress rather than a deeper layered build.

What Makes the Eco Mattress an Economically Priced Foam Mattress?

Quick answer

The Eco Mattress keeps the construction straightforward: one 9-inch premium medium-firm foam core, a Coolmax cover, a double-sided design and a 3-year warranty. It starts at £98.99 for a Single, so you can compare the actual specification rather than relying only on labels such as budget mattress, cheap foam mattress or value mattress.

I couldn’t be happier with the memory foam mattress I bought from All Foam! The quality is excellent, and you can really tell they have 40+ years of experience in foam solutions. It’s supportive, comfortable, and clearly built to last, plus it’s reassuring to know it complies with UK fire safety regulations. Ordering online was quick and easy, and delivery was fast. Highly recommend All Foam for anyone after a great quality mattress!

Buying guide

How to Choose a Budget Foam Mattress Without Buying on Price Alone

Quick answer

Compare the foam depth, firmness, exact dimensions, cover, warranty, double-sided design and bed base before ordering. A lower price can be useful, but those specifications tell you far more about whether an affordable foam mattress matches what you actually need.

Check the mattress depth

The Eco Mattress uses a 9-inch foam construction. Check the finished bed height you want and make sure a 9-inch mattress is suitable for the frame and bedding you plan to use.

Choose the correct standard size

Measure the inside of the bed frame or the top of the divan base before ordering. The Eco Mattress can currently be ordered in Single 90cm × 190cm, Double 135cm × 190cm and King Size 150cm × 198cm. Super King 180cm × 198cm is currently unavailable.

Understand the medium-firm feel

Medium-firm describes the general feel of the Eco Mattress, but the same mattress can feel different depending on body weight, sleeping position and the support provided by the bed base. Compare the construction rather than choosing from the firmness label alone.

Compare the specification, not just the words “cheap” or “budget”

Searches for a cheap foam mattress, budget mattress or affordable mattress can return very different constructions. Check whether the mattress is standard foam or memory foam, how deep it is, what cover is supplied, the firmness description and the warranty. The Eco Mattress lists those details directly so you can compare like for like.

Use the double-sided design

The Eco Mattress is designed so either side can be used as the sleeping surface. This makes it different from mattresses with a one-sided layered comfort construction. Flip and rotate the mattress as part of normal care so day-to-day use is shared across both sides.

Check the bed base

A foam mattress should sit on a level, supportive base. A damaged, bowed or uneven base can affect how the mattress feels and supports the sleeper, regardless of the price of the mattress.

Budget Foam Mattress FAQs

These answers cover budget foam mattress pricing, the 9-inch construction, Coolmax cover, medium-firm feel, double-sided design, sizes, warranty and how the Eco Mattress compares with memory foam.

Ask the All Foam Team
What is the All Foam Eco Mattress?

The All Foam Eco Mattress is an economically priced, double-sided foam mattress built with 9 inches of premium medium-firm foam and supplied with a Coolmax cover. Its two-sided design allows either side to be used while keeping the construction straightforward and lower priced than the layered premium memory foam mattress range.

Can the All Foam Eco Mattress be used on either side?

Yes. The All Foam Eco Mattress has a double-sided design, so either side can be used as the sleeping surface. Turning the mattress over as part of normal mattress care can help spread everyday use across both sides.

How thick is the All Foam Eco Mattress?

The mattress uses a 9-inch foam construction. Its overall depth sits within the range of the premium All Foam mattresses, but the Eco Mattress uses a simpler single-foam construction rather than separate memory foam comfort and support layers.

What firmness is the All Foam Eco Mattress?

The All Foam Eco Mattress uses premium medium-firm foam. Firmness is a guide to the general feel and can be experienced differently depending on body weight, sleeping position and the bed base underneath.

What cover does the All Foam Eco Mattress have?

The All Foam Eco Mattress is supplied with a Coolmax cover. The product card identifies the cover separately from the 9-inch foam construction so you can see exactly what is included.

What sizes are available?

The All Foam Eco Mattress can currently be ordered in Single, Double and King Size. Super King at 180cm × 198cm is currently unavailable.

How much does the All Foam Eco Mattress cost?

For one mattress, Single is £98.99 and Double is £161.99 because each sits below the £170 promotion threshold. King Size is £273.37 after the current 10% checkout offer, reduced from £303.74. Super King is currently unavailable.

What warranty does the All Foam Eco Mattress include?

The All Foam Eco Mattress includes a 3-year warranty, subject to the published warranty terms. This warranty is specific to the Eco Mattress and is separate from the 6-year warranty offered on the premium All Foam mattress range.

How is the Eco Mattress different from the premium memory foam mattresses?

The Eco Mattress uses a simpler 9-inch medium-firm foam construction and has a 3-year warranty. The premium mattress range uses layered constructions with memory foam comfort layers and carries a 6-year warranty.

Is the All Foam Eco Mattress a memory foam mattress?

No. The Eco Mattress uses a single 9-inch premium medium-firm foam construction rather than a separate memory foam comfort layer. If you specifically want memory foam, compare the premium All Foam memory foam mattress range.

Is a 9-inch foam mattress thick enough?

Whether a 9-inch mattress suits you depends on factors including body weight, sleeping position, the bed base and the feel you prefer. The Eco Mattress uses a straightforward medium-firm foam construction, while the premium All Foam range uses separate comfort and support layers, so compare the complete constructions before ordering.

Can I buy a single foam mattress for under £100?

Yes. The standard Single All Foam Eco Mattress price is £98.99. It includes the 9-inch medium-firm foam construction, Coolmax cover, double-sided design and 3-year warranty shown on this page.

Is a budget foam mattress the same as a cheap foam mattress?

People often use budget foam mattress, affordable foam mattress and cheap foam mattress to describe lower-priced options. Price alone does not tell you the construction, so compare the foam depth, firmness, cover, warranty, available sizes and whether the mattress is one-sided or designed to be used on either side.

What should I compare when choosing an affordable foam mattress?

Compare the actual foam depth, firmness, mattress dimensions, cover, warranty, bed-base requirements and whether you want a simple single-piece foam construction or a deeper layered memory foam mattress. These details are more useful than choosing from price wording alone.
