What is the difference between a small double and a double mattress?

6in (15cm) of width. A double is 4ft 6in (135cm) wide, a small double is 4ft (120cm). Both are 6ft 3in (190cm) long.

Is a 3/4 mattress the same as a small double?

In current use, yes: both mean 4ft x 6ft 3in. Older three quarter frames predate the modern standard sizes, so measure the frame if it is an antique or secondhand piece.

Can two adults sleep on a small double?

Comfortably as an occasional guest bed, and it suits couples who sleep close. At 120cm it gives each person 60cm, which is less than a single bed gives one person, so as an everyday bed for two it feels narrow to most people.

Does a small double take double bedding?

Fitted sheets need to be small double specifically, since a double fitted sheet is too wide and will not stay tucked. A double duvet works well on a small double and many people prefer the extra overhang.

Will a small double mattress fit a double bed frame?

No. It would leave a 6in gap across the width of the frame. The mattress and the frame have to be the same size.

Q: What size is a small double mattress?

4ft x 6ft 3in, or 120 x 190cm. The length is the same as a double; only the width differs.

Small double mattress size

A small double, also called a 4ft mattress, measures 120 x 190cm in the UK and Ireland. That's 30cm wider than a single and 15cm narrower than a standard double, with the same 190cm length. Measure inside the bed frame before ordering, as European sizes differ.

Small double mattresses in the range

The range here is small. The Serenity Sleep Aloe Vera small double has a knitted cover and foam construction with what the supplier calls a moderate firmness. The Victoria Bellini Lusso 3000 is wrapped in a soft-touch, breathable fabric. Check each product page for the full specification.

Is a small double big enough for two?

It works for two people occasionally, such as guests, but most couples find a double or king size more comfortable every night.

Choosing firmness

Side sleepers often prefer a softer or medium feel; back and front sleepers often prefer medium to firm. For a guest room, a medium mattress suits most people.

Looking after a small double mattress

Rotate the mattress head to foot every few months so it wears evenly, and use a mattress protector to keep it clean. A double-sided mattress can also be turned over; a one-sided or pillow top mattress should only be rotated. A new mattress can smell of its fillings for a few days, so let it air with the bedding off.

Delivery

Mattresses are delivered in 2 to 3 weeks unless the product page says otherwise. Our own team delivers across Northern Ireland and the Republic of Ireland and carries the mattress into the room you choose, rather than leaving it at the door.
