The Halkyn is an excellent quality guest bed finished is a very stylish White & Oak. Both beds are standard 3ft single size and come with optional Reflex Foam mattresses. You can add the mattresses via the drop down box above. They are vacuum packed with a medium to firm feel and have a removable cover for washing. The mattresses are 15 cm in depth so the mattress for the under-bed will be well within the depth restriction of 18 cm. The beds are finished with solid slatted bases.
