Every detail has been thoughtfully designed, rigorously tested and expertly crafted to deliver long-lasting performance for every type of sleeper.
At its core is PostureTech™ 2.0, Sealy’s new smart spring technology. This is no ordinary spring. The unique geometry of the PostureTech 2.0 spring responds to your individual body shape to provide deep-down support. Delivering consistent support right across the sleep surface, it is designed to distribute weight evenly and help maintain a natural shape and healthy posture. PostureTech 2.0 uses a higher gauge wire for greater stability and performance resilience over time. Twice tempered and rigorously tested by Sealy Scientists, it delivers enduring quality making lumpy and uneven mattresses a thing of the past.
EdgeGuard pushes the boundaries to maximise the sleeping area of your bed. This unique innovation surrounds the spring system, reinforcing both the sides and edges of the mattress, stabilising every inch and extending the usable sleep surface. Whether you prefer sleeping right to the edge or simply need somewhere to sit while putting on your socks, EdgeGuard makes the most of your mattress.
Enhancing the support system is the smart comfort architecture a double layer of OptiForm™ medium foam, gently cushions and adapts to your body. The result is a perfectly balanced feel that delivers support without compromising on resilience.
Designed with responsibility in mind. From TCPP-free foams to a glue free construction that improves recyclability, every layer has been thoughtfully considered delivering sustainable progress without compromising comfort or durability.

I’ve got a problem, how do I make a claim?
To make a claim you will need to have your proof of purchase or delivery.
Any claim made under this guarantee must be made through the retailer from whom the bed was purchased. Please ensure you retain your receipt as proof of purchase. Any claim must be made no later than 5 years, or 7 years for Elevate and Elevate Ultra mattresses, from the date of purchase.

Your legal rights as a consumer are not affected by this guarantee.
Terms and Conditions of your Full Manufacturer’s Guarantee.
This guarantee does not affect your consumer rights.
Our mattresses should not be rolled or bent – this could distort the spring system which in turn may affect the upholstery layers. This applies on delivery and if you need to move the mattress from room to room or house to house.
Please do not attempt to modify alter or adapt your mattress, bed or headboard as this will invalidate your guarantee.
All Sealy products must have been used in accordance with the care instructions, including being turned and rotated ‘head-to-toe’ if double sided or rotated ‘head-to-toe’ if single sided, to help with settling the cushioning layers.
Single sided mattresses should only ever be used on the sleeping surface intended. Under no circumstance should the underside of the mattress be used as a sleeping surface.
Sealy reserves the right to substitute products or materials should the original no longer be available and cannot undertake to match items not under complaint. This does not affect the purchaser’s statutory rights.
The mattress should not be used without bed linen and we recommend that you use a breathable mattress protector from new to maintain your mattress.
The mattress must be used with a suitable base – one which will provide suitable adequate support e.g. with slatted bed frames the slat widths should be 10cm and the gap between them no more than 7.5 cm.
The weight tolerance of 7kg on the small drawers, 15kg on the standard drawer and 40kg on ottoman beds has not been exceeded.
We will be unable to accept a claim if the product has been subjected to unfair wear and tear.
We are unable to accept items that are soiled or unhygienic.
This guarantee does not cover accidental damage and only covers defects in manufacture, materials or workmanship.
We may choose to instruct an independent third party specialist to carry out an in home assessment of your product and claim to assist in our decision making.
This guarantee only applies to Sealy products that have been purchased from an authorised retailer in the UK and Republic of Ireland.
This guarantee only applies to domestic products that have been purchased and used in a domestic setting. This guarantee does not apply to commercial products or premises.
This guarantee applies only to the original purchaser and can’t be transferred to anyone else if you decide to sell your Sealy product within the guarantee period.
This guarantee is a manufacturer’s guarantee and as such we are unable to offer any refunds.
This guarantee is a manufacturer’s guarantee and is limited to repair or replacement at our discretion. You may have additional rights under the Consumer Rights Act 2015 with your retailer.
