London UK, London Ontario? If Ontario we got a great one from Sears. You can get a free upgrade on the mattress if you ask for it. We went with a queen size for the comfort of any guests that use it.

I would recommend two options.....different price points and perhaps availability limitations:

1. American Leather about $2500+ for a queen size. Not so long when opened as the mattress starts close to the back of sofa. Has foam mattress with replaceable sections if damaged. Very comfortable for two adults

2. ikea karlstad for about $850 and opens into a queen bed. We bought this for various reasons:
A, price, (includes slip cover and mattress pads
B. comes in sections ready for assembly. Easy & Not so heavy
C. Replaceable slip cushions to address spills or change color ($100 for a washable fabric in the fabric we chose. Others may be higher). These are in stock in their stores.
D. Has some storage under the bed for sheets, blanket,etc.
E. You sleep"sideways, so it also has a smaller footprint than traditional sleeps
F. It's comfortable-- very firm, no bar and comes with mattress pads for both a single or queen sleep (I.e., whether you open or just sleep on the sofa w/o the back pillows.
G. The only cushions you need to store are the two back cushions. The seat cushion fold out and is supported by a pull out tray (storage compartment)
H. Fits standard queen sheets
B. inexpensive, replaceable slip cover -$100 that come in

Thank you for you suggestions. We are empty nesters now so down sizing. LIving in London UK. Will check out the IKEA option.

You are welcome. There are other Ikea options, but we selected the Karlstad. Sofabeds .are usually firmer than normal sofas, so definitely sit/lounge on it b4 you decide.

Have fun!
