This base is great. We sadly had to purchase a flat-pack base because we couldn't get our divan up the stairs of our new house. I ummed and ahhed about this for a while but so glad I bought it. It took about 20 minutes to put together by myself (30-something female) and is very strong. I have a very heavy Harrison Spinks mattress and so far, so good. Very comfy base and plenty of storage underneath. Five stars!
