The Sealy Nelson Luxury is a handmade-to-order soft mattress made exclusively for Land of Beds, built around Sealy's patented AlignSupport™ Coil spring system. Twice heat-treated for an initial response and deep-down support, the coils work alongside a double layer of InfiniLux™ Comfort Layer and Sealy Medium Softness Foam to deliver sumptuous pressure relief from the moment you climb into bed. The SmarTex™ Fibre Cover draws moisture away to help regulate your temperature, while the ProShield® treatment keeps allergens at bay for a cooler, more hygienic night's sleep - a genuine NBF Bed Product of the Year winner, proudly made in Cumbria, Great Britain.
A soft mattress built around Sealy's patented AlignSupport™ Coil spring system, best suited to sleepers who want a plush, pressure-relieving feel, effective moisture management and an allergen-resistant sleep surface, made exclusively for Land of Beds.
Soft Feel - 1/6: Our softest tension, designed for maximum comfort and pressure relief. Ideal for side sleepers, this feel allows shoulders and hips to gently sink into the mattress for a cushioned, cosy night's sleep.

Vs firmer mattresses: The Nelson Luxury's soft feel and double comfort layers give noticeably more pressure relief at the shoulders and hips than a firmer mattress. If you sleep on your side or want a plush, sink-in feel, this is the better choice. Firmer mattresses suit heavier sleepers or those who want a more rigid, supportive surface.
Vs softer mattresses: Within the soft category, the AlignSupport™ Coil and BasePlank foundation give this mattress more structural support underneath its plush comfort layers than many soft mattresses offer, helping it maintain its shape over time.
Vs premium and luxury mattresses: This mattress shares the same patented AlignSupport™ Coil technology and handmade-to-order construction found in higher-priced Sealy ranges. The difference is typically in the depth and number of comfort layers, rather than any compromise in spring quality or craftsmanship.
The Nelson Luxury is backed by Sealy's 7-year manufacturer's guarantee against defects in materials and workmanship. Given the patented AlignSupport™ Coil construction and handmade-to-order build, this is a mattress designed to last - the guarantee reflects that.
NBF Winner - Bed Product of the Year Award 2025-2026 - Recognised by the National Bed Federation as one of the best bed products of the year, reflecting excellence in design, comfort and manufacturing quality.
ProShield® Treatment - Endorsed by Allergy UK - Independently endorsed by Allergy UK, confirming the anti-allergen treatment meets recognised standards for reducing allergen exposure.
The Nelson Luxury delivers a genuinely plush, pressure-relieving feel backed by Sealy's patented AlignSupport™ Coil technology and an award-winning build quality. If you're a side sleeper looking for a soft, sumptuous mattress with effective cooling and allergen protection, this is well worth a closer look.
Choosing a mattress online takes trust. That's why the Nelson Luxury comes with a 100 night comfort guarantee - if it doesn't feel right, we'll exchange it. View the full mattress trial policy.
