Spring King Mattress Review
Spring King® is a UK-based mattress manufacturer that produces pocket-sprung mattresses designed with comfort and support in mind. Their mattresses combine pocket springs with pressure relieving memory foam, and natural fillings such as wool and silk in selected models, aiming to deliver a restful night’s sleep at an affordable price point.
But how do Spring King mattresses perform in real life?
In this detailed review, we’ll examine its construction, comfort, support, and overall value to help you decide if it’s the right choice for you.
1. Construction and Materials
The Spring King® mattress range uses individually pocketed springs that respond independently to your body shape, contouring to provide personalised support and reducing pressure points.
Depending on the model, comfort layers may include natural fillings such as wool, silk, memory foam, or a stitched pillow top for added cushioning, allowing you to choose a feel that best suits your sleeping preferences.
The Spring King® Sanctuary Spa 2000 Pillow Top Mattress is 29cm deep and features a 2000-spring base and a soft pillow top that blends comfort with structural support. The stitched pillow top includes memory foam-like comfort layers that help distribute weight evenly and enhance the overall feel. The mattress is be hypoallergenic, making the suitable for allergy-sensitive sleepers.

2. Comfort and Support
Spring King mattresses are available in a wide range of firmness options, including soft, medium, medium firm, firm, and extra firm, making them suitable for different sleeping preferences and body types.
The medium firm, firm, and extra firm models are designed to offer orthopaedic support, providing a firmer sleep surface that helps support the back and joints.
These models focus on maintaining proper spinal alignment and reducing pressure in key areas, which can be particularly beneficial for back sleepers or those who prefer a more supportive feel.
Across the range, the individually pocketed springs respond independently to movement and body weight, helping to contour the mattress to your shape while minimising pressure points.
Depending on the model, comfort layers may include foam fillings, natural materials, or cushioned tops, offering varying levels of softness while maintaining consistent support.
3. Quality and Durability
Spring King mattresses are handmade in the UK with attention to longevity and robust build quality. The combination of traditional spring units with natural fillings (wool, cotton, silk, and cashmere in some models) provides durability and resilience over time.
Customers often note that while the mattress feels supportive from day one, it may firm up slightly as it settles, which can be typical for pocket-sprung constructions of this depth.
4. Temperature Regulation
Spring King mattresses are designed to promote good temperature regulation, largely due to the natural airflow created by their pocket spring cores. The space between the springs allows heat to circulate more freely compared to dense foam-only mattresses, helping to prevent heat build-up during the night.
Depending on the model, Spring King mattresses may also include natural fillings such as wool, which is known for its temperature-regulating and moisture-wicking properties. These materials help keep the sleeping surface warm in cooler conditions and cooler when temperatures rise, contributing to a more balanced and comfortable sleep environment.
5. Motion Isolation
Pocket springs are generally good at reducing motion transfer compared with traditional open springs, and the extra comfort layers on this mattress help cushion movement. This means you’re less likely to be disturbed by a partner’s movements at night, making it a solid option for couples.
6. Trial Period, Delivery and Warranty
Spring King mattresses typically include free next-day delivery options and a 100-night sleep trial. This allows you to test the mattress at home for up to 100 nights and decide whether the firmness and comfort level suit your needs before fully committing.
Delivery is usually straightforward, and the mattress arrives ready to use — simply place it on your bed base and allow it to settle. As it’s a single-sided mattress, there’s no need to flip it, though rotating it every few months is recommended to maintain even wear.
7. Spring King Mattress Customer Reviews
Customer feedback for Spring King mattresses is largely positive, with many reviewers highlighting the high level of comfort and support offered, often noting noticeable improvements in overall sleep quality. The mattresses are frequently described as well made, thick, and luxurious, with build quality and materials receiving consistent praise, especially considering the price point.
Several customers mention that the mattresses feel firmer than expected, particularly for those with specific comfort preferences, though many view this as a positive feature due to the enhanced spinal and back support it provides. A smaller number of reviews reference delivery-related issues, though the product itself continues to receive strong approval.
