Product Description

This listing is for a King 150cm x 200cm J Marshall No. 4 Mattress (new stock). Please allow approximately 7 days delivery, sometimes quicker. 

With 1,600 pocket springs and a further 1,500 micro springs, the No.4 standard single offers quality and comfort that's hard to beat. Each pocket spring moves independently to adapt to your body shape, distribute the weight of your body across the mattress, and relieve pressure point build-up.

The many pocket springs enable you to change position without the whole mattress responding: the result is perfect spinal alignment to leave you refreshed and at your best, without disturbing your partner.

The No. 4 is hand-filled with pure new wool and cotton and wrapped in viscose and cotton Belgian Damask ticking. These breathable natural materials wick away moisture to keep your mattress at its optimum over the long-term. 

The luxurious extra Pillow Top layer is fixed to the mattress for a plush finish. Its filling is made up of the finest natural materials – pashmina, soft bamboo, alpaca, and cashmere. 

Hand made in the UK, No. 4 is hand-tufted using time-tested craftsmanship that holds the layers in place for added durability. It comes in one single tension that's suitable for all body weights. A top-quality mattress that's made to last, it comes with a 10-year guarantee. 

Every J. Marshall bed can easily be broken down and recycled. From the springs to the natural fillings, unlike some foam mattresses. 

We understand that for an optimal night's sleep, a mattress needs to be tailor-fitted to your needs, and we're committed to helping you sleep well. Contact us if you'd like a consultation on whether this mattress would be right for you.

Our delivery and assembly service

We provide a 2-man delivery service to the room of choice, as standard, on all large items to customers nationwide, using our in-house team or one of our specialist Delivery Partners. 

We will contact you ahead of the planned delivery to agree a mutually convenient delivery date, most commonly between Monday and Friday although weekends are sometimes possible. The day before the delivery you will receive a 3-hour timed slot, so you know when to stay in to receive your delivery.  On the day of delivery, our delivery team will also endeavour to keep you updated should they run into a traffic jam or get delayed by any unforeseen event. 

Our experienced delivery teams will carry your order to the room of choice (up two flights of stairs - please do let us know if it is any further), where they will unpack the order and remove and recycle any packaging, leaving you free to enjoy your new bed or mattress. For those of you who select our assembly service, the team will also install your bed or headboard so you don’t have to lift a finger.

At the time of placing the order, please do let us know if you have any planned holidays around the delivery period (we can only hold orders for 2 weeks once made, after this storage charges may apply), parking restrictions or difficult access (either inside the property or approaching the property), so we can look into the best solution for you.

Recycling your old bed or mattress

Should you no longer have a need for your old mattress or bed, we can remove and recycle this item for you (on a like-for-like basis) when delivering your new order. There will be a charge of £45 per mattress or £60 per bed for this service.


Please ensure when placing the order that the item will fit into your home and there is sufficient access to your room, for example around a tight bend in your staircase or through a narrow doorway. If you are unsure, then our showroom will be more than happy to discuss the access with you. This way we can do all that we can to ensure the item fits in. We always try our hardest to find a solution.

Small Item delivery via Courier (Bedding & Bed Linen):


For smaller items such as bedding and bed linen, we charge a flat rate of £6.00 using a Next Working Day delivery service for all mainland UK addresses excluding the most remote parts of the Scottish highlands which will carry a small surcharge.  For customers who spend over £100 on Brinkhaus bedding we offer FREE delivery.

For Northern Ireland and most other UK islands we charge a flat rate of £12. For the most remote postcodes and International addresses, we will display a message for you to contact us so that we can provide a quotation.


Parcels will be delivered by a reputable, national courier and will require a signature on delivery, unless you request for the item to be left in a safe place or with a neighbour. In most instances, you will receive a text/email message on the day of the delivery (direct from the courier company) with a 1-hour timed slot. If that time slot is not convenient there will be various options on the message to leave in a safe place, deliver on a different day or leave with a neighbour, simply follow the instructions provided.

Frequently Asked Questions


Does spring count matter in a mattress?

Yes, to a certain extent.  First and foremost is the quality of the pocket spring.  You want a high quality pocket spring providing progressive support - this is the engine of your mattress.  Once you have this, you can compare spring count, and so long as the springs are comparable in quality, as a general rule of thumb the higher the number of pocket springs in the mattress, the more supportive the mattress.  Some manufacturers will try to inflate spring count by using thousands of mini springs, however these do not provide the same level of support as a full size spring, so whilst there may appear to be more pocket springs, the level of support will not be as good.

What does mattress spring tension mean?

The tension refers to the thickness of the wire that is used in the spring and the amount of support this offers. The thicker the wire the firmer the resistance and more weight would need to be applied. Therefore for a heavier person a firmer mattress tension will offer a higher level of support, for a lighter person a softer mattress tension will be more beneficial. If you are too light for a spring tension, you will find you do not get the best level of support as you are not able to engage the springs and get the full benefit, instead you would just be resting on top of the springs.

What’s the benefit of a mattress with pocket springs?

Pocket sprung mattresses are made up of thousands of individually wrapped springs that can react and move independently based on when and where pressure is applied. This means that the springs can closely contour to the body’s weight and shape to provide the optimum level of support.

How do I know which will be the best mattress for me?

Choosing the right mattress is a very personal experience that is different for everyone. Many factors should be considered when purchasing a new mattress, such as: body height, body weight, the number of people using the mattress, who the mattress will be used by etc. For guidance and help with your choice use our helpful buying guides and ensure you find the right mattress for you. Alternatively, speak to a member of our friendly team who are very experienced and have specialist knowledge, or visit our large Hampshire showroom.

Do you offer custom/bespoke sizes?

Yes. As all our luxury mattresses and divan bases are made to order, so our manufacturers can make bespoke sizes. If this is of interest to you, please contact a member of our team who can provide you with more details. 

Is it better for my mattress to have natural upholstery fillings?

Natural upholstery fillings do prove to be a higher quality filling than those such as foam as they allow your mattress to breathe, regulate body temperature and wick away moisture from the body. However, some manmade fillings, such as Solotex and recycled eOlus, do also offer qualities like this, therefore these can also be beneficial to a mattress. Our manufacturers pride themselves in offering traceable, sustainable and recyclable upholstery fillings in each of their mattress models.
