Deep Sleep Mattress Review: Honest Thoughts from a UK Retailer
When it comes to affordable, great value mattresses, Deep Sleep is a brand that consistently flies under the radar, yet continues to impress in our showroom and online store. Known for their wide range of Bonnell and Pocket Sprung mattresses, Deep Sleep focuses on delivering comfort, durability, and solid support without overspending.
We’re proud to offer Deep Sleep products because we believe they play a key role in the market: affordable mattresses with real comfort. But, just like any brand, they’re not perfect. So here’s our honest take to help you decide whether a Deep Sleep mattress might be right for you.
A Quick Look at Deep Sleep
Deep Sleep is a Family run, Yorkshire based manufacturer that is nbf approved. They have a reputation for speedy production, good value pricing, and a strong commitment to traditional mattress construction. While they may not use the high tech or implement huge marketing campaigns of bigger names, they consistently deliver well-built, supportive mattresses across a variety of firmness levels, especially in the medium, medium-firm and firm range.
What Makes Deep Sleep Stand Out
1. Excellent Value for Money
One of Deep Sleep’s biggest strengths is their pricing. Whether you're improving a guest room, shopping for your first mattress, or replacing one on a tight budget, Deep Sleep offers incredible value at lower and mid-range price points. They also offer divan sets & bed package deals, ottoman bases, and bed frames that match in great value and good quality.
2. Wide Range of Quality Sprung Mattresses
While some brands lean heavily into foam or hybrid mattresses, Deep Sleep stays committed to classical spring-based designs and they do them very well. You’ll find a range of open coil and pocket sprung options, many with deep layers of fillings and thoughtful features like the Flexi-Edge system, which helps reinforce the sides for better edge support and durability.
3. Lots of Deep and Firm Options
If you’re after a mattress with extra depth and support, Deep Sleep delivers. Many of their models are on the thicker side, and their firm feel options are some of the best-value choices on the market for those who need that additional support, particularly popular with back and stomach sleepers.
4. Fast Turnaround Times
Unlike some major brands with long lead times, Deep Sleep has a quick manufacturing process that allows for faster delivery, making them a great choice for customers purchasing a mattress made to order, that is comfortable and without the long wait.
Things to Keep in Mind
1. 1-Year Guarantee Only
Compared to brands like Nectar offering up to a lifetime warranty, Deep Sleep’s 1-year guarantee is fairly low. It’s a trade-off for the lower price, but it does mean you’re getting less long-term peace of mind. That being said, most companies do not offer longer guarantees/warranties for open coil mattresses and lower priced pocket sprung models.
2. Not Many Soft Options
Deep Sleep caters best to those who prefer all- rounder tension mattresses or those on the firmer side. If you’re after something plush and ultra-soft, the selection may feel a bit limited. Side sleepers who love that “sink-in” feeling might be better served by a foam-heavy or deep natural model from another brand.
3. Lacks High Spring Count Models
If you're seeking a high spring count pocket mattress (e.g. 3000+ pocket sprung mattresses for extra responsiveness), Deep Sleep doesn’t currently offer those at all. Their models are solid, but not ultra-premium in terms of spring density.
4. Limited Use of High-Tech Materials
Deep Sleep mostly sticks to traditional fillings, memory foam, reflex foam and natural fillings. They do have a soft/medium gel model, featuring a Bonnell spring unit which (in Deep Sleep fashion) gives people an option of having low cost gel mattress. Other than this their focus isn't on high tech materials, unlike their sister brand Giltedge Beds.
Final Thoughts: Is Deep Sleep Right for You?
Deep Sleep is a smart choice if you’re looking for a budget-friendly, spring-based mattress with solid construction, plenty of comfort layers, and good support. Their mattresses are reliable and built with quality in mind, even if they don’t come with the extra spec.
We’ve seen Deep Sleep work especially well for:
• Back and stomach sleepers wanting firm support
• Budget shoppers wanting more mattress for their money
• Buyers furnishing a full room with bed bases, ottomans, or divans included
However, if you need something with a softer, plusher feel, a premium warranty, or advanced materials like latex or cooling gel, you might want to explore their alternate brand with the same focus on incredible value but with higher spec models: Giltedge Beds.
