The Sleepeezee Perfectly British Strand 1400 Pocket Mattress is part of the Perfectly British collection from Sleepeezee. It sits right in that ‘proper British’ pocket sprung bracket that a lot of people ask me about. On paper it’s a medium to firm, not a rock, but definitely not soft either, and one owner sums it up as ‘Firm enough with just enough give’. Not everyone agrees, a few found it softer than the label says, so don’t buy it expecting a board. The 1400 individual pocket springs that make up the mattress give a medium to firm feel. Each spring sits in its own pocket and reacts individually when you shift about, which is what you want from a pocket sprung build, rather than the whole surface moving as one.
The hand tufting ensures a comfortable surface and keeps the mattress looking beautiful for years to come. The woven Damask cover and woollen tufts give it a more ‘made’ finish than a lot of flat-top mattresses, though tufts are something you can feel: one owner put a wool topper on because ‘you can slightly feel the buttons on mattress’, and another wanted a thick protector for the same reason. A medium to firm pocket unit under wool and cotton should hold you nicely through the hips and lower back if you sleep on your back, without letting you sink in too far, which I like. On your side though, I’d expect a bit more pressure around the shoulder than I’d want, because wool and cotton over springs doesn’t give the way foam does, so if you’re a lighter side sleeper this firmness could come up a touch too firm. The Wool and Cotton comfort layer paired with the Damask cover work well to offer supreme comfort without compromise, but it’s still a fairly traditional feel, so don’t expect that slow-melting memory foam hug.
One thing I always check is the edge, and a couple of owners flag it here: one pair found the mattress a little softer at the sides than they thought it would be, and another calls it ‘Very soft on edges’, too soft to sit on the end. Not awful, but it’s not the strongest edge support at this sort of price point. The pocket springs give the mattress enough bounce-back qualities to ensure you will get a good night's sleep, but if you’re sharing with a wriggler, you’ll still notice some movement through the mattress, it’s better than open coil, but it’s not ‘dead’ either. Also worth saying, wool can sleep a bit warmer for some people, so if you run hot at night you might want to pair it with a cooler mattress protector and breathable bedding.
The mattress is manufactured in the UK and comes complete with a 10 year guarantee and an impressive 100-night comfort trial from Mattress Online (exchange only) with free delivery within the UK. For me personally, it’s a solid choice if you want that supportive, traditional pocket sprung feel, but I wouldn’t be pushing it at dedicated side sleepers who need more give through the shoulder.
