The Chapman Extra Firm offers a feel that’s robust and reassuringly supportive, crafted for those who love an extra firm feel comfort without compromising on support.
At its core is the patented AlignSupport® coil, which senses your shape and responds with deep, consistent support. Its intelligent two stage design first conforms to your body before providing dependable, long lasting stability. Every spring is twice tempered for exceptional durability.
Surrounding the spring system, UniCased® technology reinforces the mattress edge to expand the usable sleep surface and help prevent roll off, while interlocking keys minimise lateral movement. Beneath it, the BasePlank adds structural integrity and works in harmony with AlignSupport® to create a stable, reliable foundation.
Comfort is layered with purpose. Sealy Foam adapts to your body for responsive cushioning, enhanced by a ComfortCore® zone in the centre third for targeted pressure relief. Supported by an additional double layer of Sealy Firm & Extra Firm Foam to complete the architecture.
The sleep surface is finished with SmarTex® to draw away moisture and regulate temperature, and ProShield® to help keep allergens at bay for a cleaner, fresher night’s sleep. A quilted tight top and premium fabrics complete the refined, luxury aesthetic, with vertical handles added for easier manoeuvring.
Handmade in Britain and backed by a 7 year guarantee, the Chapman Extra Firm is built to last, a mattress that feels robust and supportive from the moment you lie down. Crafted with advanced support and luxurious comfort for an elevated sleep experience.

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.
