Frequently Asked Questions
Is a 12 inch memory foam mattress suitable for my 4ft6 double bed?
It is made in the 4ft6 double size of 135 x 190cm, so it suits standard UK double frames. Twelve inches is roughly 30cm, so check that your headboard and side rails leave enough height before you order.
Who would enjoy a 12 inch deep double foam mattress?
It suits couples and solo sleepers who love a deep, cushioned bed. If you like to sink into a mattress rather than lie on top, a thick memory foam mattress UK shoppers often choose for comfort is worth a look.
How does a deep memory foam mattress support my body?
A deeper foam build gives the material more room to compress around your shoulders and hips, spreading your weight across the surface. This gives the hugging, cushioned feel that memory foam is known for.
Is a 12 inch memory foam mattress soft or firm?
Depth alone does not set firmness, and this listing does not state a firmness grade. Expect the typical cushioned, moulding feel of memory foam. For a firmer surface, look at our medium firm and orthopaedic memory foam mattresses.
Will a 12 inch foam mattress make me overheat?
Thick memory foam can hold more body heat than a thinner or sprung mattress, and this one is not sold as cooling. Choose breathable bedding, keep the bedroom ventilated and avoid heavy duvets if you run warm.
What is 12 inches in centimetres, and is it deep for a mattress?
Twelve inches is about 30cm, which is a deep mattress by UK standards. It looks and feels generous, but you will need deep-fit sheets and a frame that is not too tall, so the bed stays easy to get into.
Which sheets and duvet suit a thick 4ft6 double mattress?
Choose standard double bedding, with a fitted sheet that has a pocket depth of at least 30cm. A double duvet cover will fit as normal. Shallow sheets are the most common cause of corners slipping on deep mattresses.
How do I unbox a double foam mattress and let it recover?
Place the box in the bedroom, cut the wrapping and let the mattress unroll on its base. Allow 24 hours or longer for the foam to expand fully. A thick mattress can take a little longer, so be patient.
What upkeep does a thick foam mattress need?
Turn it head to foot every few months, keep the base ventilated and get help when moving it as it can be heavy. Spot clean spills with a lightly damp cloth and let the surface dry fully before making the bed.
How does thick foam compare with a hybrid mattress for a double?
A thick foam mattress is cushioned and quiet, while a hybrid adds springs for a bouncier, more airy feel. If you prefer a close, hugging sensation, foam suits you. If you want more lift, a hybrid is worth trying.
