Budget foam mattresses often come with a catch, whether it is a narrow size range or a thin comfort layer that barely qualifies as memory foam. The Foam People‘s Core Range lists supportive and memory foam mattresses from £66.59 while still covering standard UK beds, European sizes, and the awkward dimensions found in caravans and campervans. What follows is a closer look at what sits inside that range and how the depth and material choices compare.
What the Core Range Covers: Materials and Depth Options
The Core Range groups together several mattress types rather than offering a single formula stretched across sizes. Depths across the collection run from 4-inch (10cm) supportive foam builds up to 6-inch (15cm) constructions. Some models lean toward classic memory foam feel, others toward a firmer orthopaedic-style support, and one introduces cooling technology into the mix.
Because the range is built from these distinct products rather than a single mattress resized, the practical difference between models is not just depth but also feel. A 4-inch supportive foam mattress will sit differently under a sleeper than a 6-inch mattress with a dedicated memory foam top layer, even before price is considered. This is the detail worth checking before comparing prices, since two budget foam mattresses at similar cost can still behave very differently once in use.
Westwood Core Memory Foam and Supportive Foam Mattress at £66.59
The Westwood Core Memory Foam and Supportive Foam Mattress from The Foam People is priced from £66.59, discounted from a regular price of £73.99, making it one of the more accessible entries in the Core Range. It measures 4-inch (10cm) deep and is built to combine softness with support, aimed at sleepers who want a balance between the two rather than a mattress that leans firmly one way. A related model, the Westwood Core Supportive Firm 10cm Deep Foam Mattress, is listed separately at £66.99 and is designed for a firmer, more orthopaedic-style feel rather than the blended comfort of the standard Westwood Core.
Core Bubble Memory 6-inch Deep Mattress and Medium-Firm Comfort
The Core Bubble Memory 6-inch (15cm) Deep Mattress is priced from £88.19, down from £97.99, and sits deeper in the range than the Westwood models. Its construction pairs a 2-inch (5cm) memory foam comfort layer with a 4-inch (10cm) supportive foam base, combining a firmer core with a softer feel that is attributed to the cover and the Comfort Bubble surface rather than the core itself, placing it among the deeper builds in the range alongside the CoolMax model at the same 6-inch (15cm) overall depth. The overall feel is pitched as medium to medium-firm, offering structured support underneath a surface that is noticeably softer to the touch.
Core CoolMax Memory Foam Mattress: Cooling Technology Under £93
The Core CoolMax Memory Foam Mattress is listed from £92.99 and is built to a 6-inch (15cm) depth, putting it in similar territory to the Core Bubble model in terms of construction. What separates it is the CoolMax element, described on the brand’s own site as advanced cooling technology paired with the same memory foam comfort found elsewhere in the range. For anyone specifically weighing up cheap memory foam mattresses that also address heat retention, this is the model within the Core Range built around that feature, still priced under £100.
Custom Sizing for Caravans and Campervans Without Premium Cost
Standard bed sizes are only part of what the Core Range addresses. The Foam People also lists a Core Caravan 6-inch Deep Memory Mattress, priced from £89.99 down from £99.99, described as letting the buyer choose the size to suit static caravans and camper van conversions with narrower or unusual bed dimensions. This sits alongside the standard-size Core mattresses rather than replacing them, giving caravan and campervan owners a route to a fitted mattress without moving into the higher-priced Comfort or Superior collections.
The wider site also lists custom-size caravan and campervan mattresses and toppers as separate categories, alongside static caravan mattresses in deeper builds such as the Comfort Premium 8-inch and Superior Diamond Luxury 10-inch options, both priced above the Core Range. Those alternatives sit outside the £100 threshold this article is concerned with, but their existence shows that the made-to-measure approach used in the Core Caravan mattress is not a one-off but part of how The Foam People handles non-standard bed sizes across its whole catalogue.
Free Delivery and Payment Flexibility Across All Price Points
Every product across the site, including the entire Core Range, ships with free UK delivery, and mattresses are rolled and boxed for transport. Klarna is listed as an available payment method, giving buyers a way to spread the cost of even the lower-priced Core mattresses if preferred. A on orders over £400 is also listed on the Core Range collection page, which is more relevant to bulk or multi-item orders than to a single budget purchase but is worth noting for anyone furnishing more than one bed.
- The Westwood Core Memory Foam and Supportive Foam Mattress is 4-inch (10cm) deep and priced from £66.59.
- The Westwood Core Supportive Firm 10cm Deep Foam Mattress offers a firmer alternative at the same depth for £66.99.
- The Core Bubble Memory 6-inch (15cm) Deep Mattress combines a 2-inch memory foam layer with a 4-inch supportive base, priced from £88.19.
- The Core CoolMax Memory Foam Mattress matches the 6-inch depth of the Core Bubble model while adding cooling technology, priced from £92.99.
- The Core Caravan 6-inch Deep Memory Mattress is available in custom sizes for static caravans and campervans, priced from £89.99.
Taken together, the Core Range gives a fairly clear map for matching mattress type to bed type without stepping outside a budget ceiling. Shoppers weighing up budget foam mattresses for a spare room, a static caravan, or a campervan conversion have a specific model to point to in each case, rather than a single generic product stretched to fit every use.
