Absolutely Brilliant Mattress – support, comfort & great sleep!
I’m so impressed with this mattress! From the moment I unboxed it, I could tell it was well made and of great quality. The hybrid pocket sprung and memory foam design gives the perfect balance of support and comfort, and the 7-zone support system really helps reduce pressure on my back and shoulders — I wake up feeling refreshed, not stiff. The mattress feels medium-firm which is ideal for me — not too soft but comfortably cushioned. It’s thick (approximately 12 inches) and feels very stable and durable. Breathability is excellent too; I stay cool through the night thanks to the airflow design. I also love the value for money — honestly, this mattress feels like a premium product at a very reasonable price. Delivery was quick, and although it’s a sturdy, heavy mattress, it was easy enough to set up. Overall, I’m sleeping so much better and would highly recommend this mattress to anyone looking for comfort, support, and great quality sleep.

Very comfortable and great quality.
I am extremely happy with this mattress.It expanded quickly right out of the box and reached full size within a few hours. The comfort level is perfect -supportive yet soft enough to relieve pressure points. I've been waking up with less back pain, which is a huge improvement. The quality feels excellent, and its a great value for the price.Highly recommended!

Surprisingly comfy & helps me get to & stay asleep
Having read some of the reviews I took a gamble buying this as I suffer with chronic pain throughout my body especially in my lower back & in my neck (cervical spondylosis which also effects my arms & shoulders), trapped nerves & twinges like electric jolts, add in a sprinkle of sciatica & a very large dollop of Fibromyalgia causing serious fatigue & chronic body wide pain head to toe 24/7 non stop on top of all of it, Unpacked it & used it that night, didn’t bother waiting 2 or 3 days nonsense, yet after my immediate 1st nights sleep on this I actually woke not feeling like any worse for wear like I’d been trampled on by a herd of elephants 10 times over, this mattress does not aggravated my conditions, or ramp the pain dial up worse than what I suffer with, it provides me with decent support surprisingly, helps even when side sleeping, I normally do not sleep well on my back at all, laying flat out straight on my back normally is a no go for me, with this mattress I can & it does give me support I'm not used to in the right areas, which is nice, the springs adjust in right places, side sleeping also has good support, the side edges of the mattress are firm too, so near enough no dipping/sinking off when you sit on the edges, the springs don't poke through into my back although you can feel them through the vertical sides around it when putting on a fitted sheet as you run hands down along tucking stuff in, nothing bad, nothing protruding out, the topper or top part of the mattress is ok, soft enough, but you can always add a memory foam topper for extra softness if needed, as it goes for me personally it’s fine as is, better support than my old memory foam only mattress which was providing the wrong support/no support in areas needed, I’m happy with this mattress & waking up without any additional pain on top of my conditions is a small blessing, that said we’re all different with our health conditions, for my problems it’s not making things worse, very happy with this product for what it does for me. If you decide to buy this coming from memory foam only then be aware this is a lot firmer/more rigid, the springs are not super soft bouncy, but enough you can bounce on it if you want too, the instructions say to bounce on it to help it shape/break in, oh aye 🤣 Decent product as described.

Slily Double Mattress
I purchased this Slily double mattress after having looked at dozens of others on various websites. I had never heard of the brand before and was in two minds about buying it, however the majority of reviews were positive, so based on that, and the good discount, I decided to take the risk and buy it; and I'm so glad I did. The mattress is firm, but very comfortable, which is what I was looking for due to having arthritis of multiple joints. The height of the matress is definitely touching 12 inches with a good solid spring support 'base' topped with comfortable memory foam. I had to get my son-in-law to lift the box/matress up the stairs as it is a heavy item, so keep that in mind, and I was actually able to sleep on it that night. Also, take care when taking the mattress out of the box as it does spring open. There's also a nifty wee tool for cutting through the mattress wrapper. All in, I would say I that I would buy this matress again with no hesitation. I have given a four star rating for now, for no other reason than only having slept on the matress for eight nights so far so I have no idea how the firmness and comfort of the matress will be in the future.... but I am genuinely very happy with my purchase at the moment. If anything changes though, I will, update my review in the future.

Amazing top quality mattress.
I ordered the mattress for my son and he really loves it. It is very comfortable and relaxing, as compared to the old one we had. This one is less in price and is best in quality. He sleeps well at night.

Highly recommended 5 star mattress.
I purchased this mattress about 2 months ago and it is the most comfy supportive mattress I’ve ever slept on. No nasty smells when I first opened it, and I slept on it the same night I opened it around 4 to 5 hours later. Doesnt dip when you sleep on it, however when you sit on the side of the bed it does dip slightly but goes straight back when you get up. The sides are supportive,it’s not a bouncy mattress it’s firm and comfortable. Perfect for any sleeper,I’m a front sleeper and it supports my whole body so I don’t wake with a bad back like I did on my old more expensive Matress. Highly recommend this mattress.will post a picture when I change my bedding.

Ich bin wirklich positiv überrascht! Die Matratze in der Größe 140×200 cm ist sehr bequem und bietet eine perfekte Balance aus weich und stützend. Seit ich darauf schlafe, wache ich morgens viel erholter auf und habe keine Rückenschmerzen mehr. Die Verarbeitung wirkt hochwertig, der Bezug fühlt sich angenehm an und die Matratze hat sich nach dem Auspacken schnell entfaltet – ohne starken Geruch. Auch die Liegefläche bleibt stabil und hängt nicht durch. Für diesen Preis bekommt man wirklich tolle Qualität. Ich würde sie jederzeit wieder kaufen und kann sie definitiv weiterempfehlen!

J’aime vraiment ce matelas à ressorts. Avant, j’avais acheté un matelas en mousse pour 70 euros, et quand on appuyait dessus avec la main, il semblait dur, mais en réalité, une fois couché dessus, il était très mou et manquait de soutien. En voyant ce matelas à ressorts ensachés, je me suis dit que vu le souci du détail, il devait offrir un bon soutien, et en effet, une fois couché dessus, il est très confortable et ne s’affaisse pas !

⭐⭐⭐⭐☆ (4 von 5 Sternen) Ich habe mir eine harte Matratze in Kombination mit einem harten Topper gekauft, nachdem ich zuvor jahrelang auf einer sehr weichen Schaumstoffmatratze geschlafen habe. Der Unterschied war – ehrlich gesagt – anfangs richtig ungewohnt. Es hat ein paar Tage gedauert, bis sich mein Körper an das neue Liegegefühl gewöhnt hat. Die Liegefläche ist sehr fest – wer dieses typische "Reinsinken" oder ein leichtes Nachgeben gewohnt ist (wie bei Schaumstoff), wird das hier definitiv nicht finden. Auch dieses leicht „schaukelnde“ Gefühl, das ich beim Bewegen auf weicherem Material hatte, fehlt mir etwas. Es ist einfach nur stabil – da bewegt sich nichts mit. Aber: Das hat auch seine Vorteile. ✅ Was ich jetzt als positiv empfinde: Ich habe viel mehr Halt beim Liegen. Besonders beim Aufstehen merke ich, dass es mir jetzt leichter fällt, weil ich nicht mehr "aus einem weichen Loch" hochkommen muss. Der Topper verrutscht kaum, weil er Spannbänder an den Ecken hat – das ist super praktisch und funktioniert sehr gut. ❌ Kleiner Nachteil: Die Matratze und der Topper waren wirklich schwer – ich habe sie alleine getragen bzw. geschoben und hatte danach leider Rückenschmerzen, die noch ein bisschen anhalten. Wer empfindlich ist oder keine Hilfe beim Aufbauen hat, sollte das einplanen. 📌 Insgesamt finde ich die Kombination aus Topper & Matratze jetzt in Ordnung bis gut. Der Liegekomfort ist stabil, aber eben sehr fest – Geschmackssache. Ich vermisse ein bisschen die weiche „Ein-Kuschel-Zone“, aber merke, dass mein Rücken inzwischen mit der festeren Unterlage besser zurechtkommt. 🌟 Fazit: Ideal für alle, die sehr fest liegen wollen und Probleme mit zu weichen Matratzen hatten. Wer aber dieses weiche, schwingende Gefühl beim Hinlegen liebt, sollte sich das genau überlegen. Ein Stern Abzug wegen der anfänglichen Umgewöhnung und dem wirklich schweren Handling. Personen unter 150kg würde ich empfehlen sie sollen eine weichere Matratze nehmen außer sie mögen es so hart😉 → 4 von 5 Sternen – insgesamt stabil, rutschfest, hochwertig, aber mit einer kurzen Eingewöhnungsphase.
