We've got a Millbrook Smooth Tech Luxury 5000 Pocket Mattress on the cards today and what a fantastic offering from the popular and prestigious manufacturer. For those not in the know, Millbrook Beds are well established in the arena, selling primarily higher quality products in the mid-tier price point. They represent a great opportunity for those that are looking for a more premium nights sleep and the Smooth Tech 5000 Pocket takes that and dials it all the way up to 100. Let's jump into what this one is all about.
First, the support layer; 5000 premium pocketed springs that are housed in their own individual fabric pockets, all ready to contour to your each and every movement. Available in a soft-medium tension, these springs will best suit side sleepers and will allow you to fully sink your hips and shoulders into the depths of the mattress while you sleep. Back sleepers may be satisfied with this degree of tension also, though should consider something firmer if they are heavier than standard as the sinkage may otherwise be suitable.
Onto the comfort layer which sits at the top of the mattress and you get natural fillings of wool and cotton, available in a deep layer that proves to be both breathable and luxurious. This type of mix works well for many people that get too hot at night and require something more ‘all-season' that will allow them to sleep deeper and longer. It has been an industry trick for decades to not be specific about the exact GSM of the fillings in mattresses, to help create a bubble of uncertainty. This isn't changing with the Smooth Tech Luxury 5000 unfortunately, but, just look at the size of the thing, you can see the sheer volume of fillings from a mile away and it is clear that the quality and structure of the mattress will keep you comfortable for years to come.
You get a 10-year warranty, plus Mattress Online's 100-Night Comfort Trial if you buy their protector with the mattress. The trial lets you exchange the mattress rather than get a refund if the comfort isn't right.
Owners mostly describe it as comfortable, and several mention the support. One wrote "Great mattress very comfy but with plenty of support", and another praised the "Good solid construction, great medium firmness". One owner did find it a "bit firmer than expected". Another blamed the handle placement after they "had a really difficult time trying to turn it".
