Rank #2 in Best Double Mattress 2026: 10 Ranked, and Where the Spec Sheets Disagree
Resspry 12 Inch Hybrid Pocket Spring Mattress, Double
Price and rating as shown on Amazon when we collected them. Both change.
The Resspry Navyx is a 12-inch hybrid double mattress — pocketed coils with a memory foam comfort layer — selling at £161.49 and sitting second in this guide. It is the thickest mattress in the list, at a listed 30 cm, and also the heaviest at 27.6 kg. That fits the pattern running through this category: the other mattresses here are listed at 25 cm and weigh between 23.9 kg and 28.5 kg, so thicker means heavier almost everywhere except in one listing. The size fields on this one also agree with each other, which is not something every mattress in this guide manages.
Where this listing gets slippery is its own labels and its own counts. The firmness field says Medium Firm, while the Material Type field in the same listing says Medium. The headline rating of 4.6 comes from 439 ratings, but the star breakdown shown covers only 100 of them: 83 five-star, 9 four-star, 4 three-star, 1 two-star and 3 one-star. Every figure on this page is taken from the Amazon listing for this mattress — we have not tested it ourselves.

What buyers actually say
Quoted from customer reviews on Amazon
Verified purchase“I'm really happy with this mattress. It was easy to set up and expanded to its full size within a short time. The medium-firm support is just right—comfortable while still providing good support for my back. I've been sleeping much better since I started using it. The mattress also feels breathable and doesn't get too warm during the night. For the price, the quality exceeded my expectations. I would definitely recommend it to anyone looking for a comfortable and affordable king-size mattress.”
Verified purchase“I've been using it regularly and have been really pleased with how comfortable it feels at night. The firmness is well balanced, so it provides good support without feeling uncomfortable or overly hard. I like the way the mattress supports my body while still having enough cushioning on top. The 12-inch profile also makes the bed feel much more substantial. Overall, it has been a noticeable improvement compared with my previous mattress, and I'm very happy with the quality and comfort.”

Questions people ask
How thick is the Resspry Navyx mattress?
The listing gives 30 cm in three separate places: the size field (135 x 190 x 30 cm), the item thickness and the item depth. The style name calls it 12 inch, which is roughly 30.5 cm, so the two agree closely here.
Is it medium or medium firm?
The listing uses both words. The firmness field says Medium Firm, the product name says Medium Double Bed, and the Material Type field says Medium. The reviews describe the support as medium-firm.
How many springs does it have?
The listing does not state a spring count. It says the Navyx uses a VAJRA spring induction system with pocketed coils across four layers, and cites 30,000 pressure tests behind the anti-interference claim.
How heavy is it?
The item weight is listed as 27.6 kg. For comparison, the other mattresses in this guide are listed between 23.9 kg and 28.5 kg.
How long does it take to expand?
The bullet says the vacuum-packed mattress expands fully within 72 hours once opened. One reviewer reports it reaching full size within a short time instead.
Can I roll it back up?
No. The listing says that once opened it cannot be re-rolled, and adds that the handle is for decoration only.
