Wanted a thicker mattress for my sofa bed. Not able to fold this into the bed but not to bothered as can stand t he mattress behind the sofa. Mattress is light and quite easy to manoeuvre.  It was delivered within afew days of ordering, which was great way before it's given delivery date. That gave me time to "air" the mattress as it does have the kinda chemical/damp sort of smell. I left out in the garden, unwrapped to get the smell out and it worked. It only had a very slight smell afterwards but after being used it is now fine. Did the job, fold out bed now much more comfortable. No complaints. BRILL!!!
