Frequently Asked Questions

How big are Ecosa super king sofa beds?

Ecosa super king sofa beds are 3.5 seaters (however, please note that our 3.5-seater sofas with in-built storage convert into double beds). Sofa bed dimensions vary, so please check the individual product pages for specific details.

What other sizes do Ecosa sofa beds come in?

As well as our super king bed size sofa bed, Ecosa sofa beds come in long single or king single (for our 1.5-seater armchair sofa beds), double and queen-sized options.

What size sheet can you use on a super king sofa bed?

A super king sofa bed from Ecosa takes standard super king-sized sheets.

How can you make a sofa bed more comfortable?

To make a sofa bed more comfortable, add breathable bedding, a lightweight quilt or blanket and a high-quality pillow like the Ecosa Pillow. Recommended by CHOICE, our contoured, memory foam pillow delivers dreamy neck support for all sleep positions and is height-adjustable for custom comfort.

If the sofa bed is old or the mattress doesn’t suit your guests’ firmness preference, a mattress topper can add support and make it softer or firmer.

How do you convert a sofa into a bed?

Brands use a variety of mechanisms in their sofa beds, but we’ve kept things simple. To convert your Ecosa sofa into a bed, remove any decorative cushions and pull/fold out your mattress from the top. Voilà – a comfy bed in seconds!
