Review: 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.
Review: 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.
