Best for
Not ideal for
4000 Pocket Spring Double Layer System
What it is: A double layer pocket spring construction totalling 4000 individually wrapped springs, each moving independently to respond to your body's shape and weight.
How it helps you sleep: Each spring settles back into place as you move, keeping support consistent across the whole mattress and reducing motion passed on to your partner.
Handcrafted Pillow Top
What it is: An additional layer of cushioning built into the top of the mattress, sitting above the supportive spring system.
How it helps you sleep: Delivers a sumptuously soft, body-hugging surface on entry while the layers beneath maintain support through the night.
Cashmere & British Wool Blended Layer
What it is: A blended layer of cashmere and British wool fibres, combining cashmere's ultra-soft texture with wool's strength and durability.
How it helps you sleep: Cashmere adapts to your body temperature, keeping you cosy in winter and cool in summer, while the wool fibres add structural support and resilience beneath the softness.
British Wool Layer
What it is: A soft, insulating layer of Red Tractor Assured British wool used as an upholstery layer within the mattress.
How it helps you sleep: Wool is a natural insulator, keeping you cool in summer and warm in winter, and its hygroscopic properties help draw moisture away from the body.
Eco Support Layer
What it is: A supportive fibre layer made from recycled materials, chosen for its rebound properties.
How it helps you sleep: Reinforces the mattress structure beneath the softer layers, helping the mattress keep its shape and supportive feel for longer.
4 Rows of Hand Side Stitching
What it is: Traditional hand side stitching, carried out by senior upholsterers, securing the outer springs to the border along the top and bottom of the mattress.
How it helps you sleep: Strengthens the borders and edges, preventing the springs from distorting and extending the usable sleeping area right to the edge of the mattress.
Pure Damask Cover
What it is: A soft-to-the-touch damask cover in 100% Viscose.
How it helps you sleep: Provides a soft, fresh and hygienic sleeping surface.
Hand-Tufted with Woollen Tufts
What it is: A traditional upholstery method where fillings are secured by hand with woollen tufts from top to bottom of the mattress.
How it helps you sleep: Keeps all loose fillings secured in place, maintaining the mattress's shape and finish over time.
Flag-Stitched Handles
What it is: Handles fitted to both sides of the mattress.
How it helps you sleep: Makes it easier to position and rotate the mattress when needed.
Chrome Air Vents
What it is: Chrome-finished vents built into the mattress sides.
How it helps you sleep: Allow air to circulate through the mattress, helping regulate temperature and keep it fresh.

Vs firmer mattresses: The Pillow Top and cashmere comfort layers give noticeably more cushioning at the shoulders and hips than a firmer alternative. If you sleep on your side and want a plush, body-hugging feel, this is likely the better choice. Firmer mattresses suit heavier sleepers or those who want a more rigid, supportive surface.
Vs medium mattresses: This mattress sits at the softer end of our range, giving side sleepers more cushioning and pressure relief than a medium-feel mattress, while the double layer spring system still provides a little extra stability compared to our softest options.
Vs synthetic-filled mattresses: This mattress is entirely foam-free, built instead from natural cashmere, British wool and a recycled Eco Support Layer. These materials are naturally breathable and better at regulating temperature than synthetic foam fillings.
The Heritage 4000 is backed by Sleepeezee's 10-year manufacturer's guarantee against defects in materials and workmanship. Given the quality of the natural fillings and hand-finished construction, this is a mattress built to last - the guarantee reflects that.
National Bed Federation (NBF) Approved - Independently verified to meet strict UK standards for quality, safety and responsible manufacturing.
Sleepeezee Royal Warrant Holder - Sleepeezee is a proud supplier to the Royal Households, a standard of craftsmanship that has to be earned and maintained.
The Heritage 4000 delivers a rare combination: genuine luxury feel, natural foam-free materials and plush, body-hugging comfort - all handcrafted in Britain and backed by a 10-year guarantee. If you're a side sleeper who wants a mattress built from natural, breathable fillings, this is one to consider.
Choosing a mattress online takes trust. That's why the Heritage 4000 comes with a 60 night comfort guarantee - if it doesn't feel right, we'll exchange it. View the full mattress trial policy.
