The Super Reflex Foam Firm Mattress is a reflex foam mattress with a firm feel. Those terms describe this model’s listed construction and comfort rating, making comparison with the other mattresses in the range straightforward.

Available configurations

  • Size: Single 3FT, Small Double 4FT, Double 4FT6, King 5FT and Super King 6FT.

Product details

It is offered in Single 3FT, Small Double 4FT, Double 4FT6, King 5FT and Super King 6FT. Select the size that matches your bed frame; the mattress is sold as the selected size only, and a bed frame or headboard is not part of this product. The firmness label is a useful comparison point, although comfort remains personal and can feel different according to body weight and sleep position.

Use the size selector to review the precise choice and current price before adding it to your basket. The configuration page also presents optional mattress-related services separately; those services are not part of the mattress itself unless deliberately selected.

For ongoing care, use a compatible supportive base, follow the care instructions supplied with the mattress and rotate it only where the product guidance recommends doing so. Measure the intended frame and access route ahead of checkout, particularly for larger UK sizes.

Choosing this configuration

The shown starting price belongs to the default configuration. Size, headboard height, upholstery, button treatment and storage can alter the total where those selectors appear. The updated amount beside the chosen configuration is the relevant price for comparison and checkout.

Treat the option names as distinct specifications, not interchangeable labels. A no-storage base does not include a concealed compartment, while a drawer or gas-lift choice changes the configured product. Read the selected line item in the basket before payment and keep a copy with your order.

Before ordering

Review every chosen option in the basket, as changing size, upholstery, headboard height, button finish or storage can change the final price and availability. Product photography represents the design, while fabric appearance can vary with lighting and screen settings. Dimensions should be checked against the room and delivery route. Only the configuration and any services explicitly selected at checkout form part of the order.
